rating of septic tanks for a country house 2018 (TOP -10)

And then the moment came when the relief of the site was planned, the dream house was built from reliable material, it remains to complete only a couple of moments related to convenience and nature ... competent solution of this issue. Namely, the choice of an autonomous sewage system or a septic tank, which will allow you to purify wastewater and preserve the environment. Therefore, the only way out is to install a septic tank, which decomposes sewage and fecal matter into almost pure water and harmless sludge. Is it better to choose a Los or a septic tank for a country house? But what's the best septic tank or salmon? What is suitable for me for temporary or (all-season) permanent residence? What does the rating of volatile or non-volatile septic tanks look like? This is probably one of the most difficult questions when building a house. We strive to always get the best in our life, as this guarantees us peace of mind and reliability. Everyone asked such a question, building their dream home, choosing a plot or materials that are the most reliable and of the highest quality on the market. I would like to compare in order to understand the rating. Choose the best septic tank for yourself. Understand what quality septic tank has a great guarantee.

The history of the septic tank

Long gone are the days when a "birdhouse" on the street was arranged for everyone in a private house. The modern standard of a comfortable life, even in the country, presupposes the presence of a normal toilet and, at least, a shower. And in the house there is often more than one bathroom, and in addition, a lot of household appliances. To ensure the required level of comfort, the sewage system for a private house must be done correctly and its basis is the choice of a method for processing wastewater. Since the correct selection and subsequent disposal of wastewater will ensure a comfortable stay on the site.

The best article /

What will we get from this article? - MAXIMUM in order to choose a septic tank / Los. We will also pay attention to the definitions, principles of operation of various treatment plants, the most popular and effective models. We will determine how to choose the best septic tank for your home or summer cottage. And what characteristics must be considered when choosing the best septic tank or VOC for a country house. It is important not to be mistaken in choosing the best sewage solution for yourself.

Variations of the Best Septic Tank or in 2018

Today is already 2018 and in our modern world there is very strong competition and it is very difficult for any consumer to make the right choice in favor of reliability, quality and peace of mind. Plunging completely into this very interesting topic, you understand how many of them, variations, materials, pros and cons. Septic tanks, VOCs and storage tanks - we fully define what is what? Since many people confuse the name of a septic tank with an autonomous sewage system.

For temporary residence

For permanent residence

DESCRIPTION: Storage tank, or.

We suggest that you familiarize yourself with the general definition of what systems are and what they are intended for. Below is a block of information for understanding the principle and operation of wastewater treatment and storage systems. Therefore, the best septic tank for home and summer cottages will be your own. We will start with the simplest - definitions and explanations of what is what.

A storage tank is a reservoir, from the word (fr. Réserve from lat. Reservare - to preserve), intended for the accumulation of household waste water from the sewerage system. The main purpose is the accumulation and storage of sewage, household waste, etc. The purpose of the storage tank, in the case of wastewater collection, is to exclude direct emissions into the environment (ditch, soil, water). This technological solution allows you to preserve the ecological environment in your and neighboring area. The storage tank does not process or purify waste water from the sewerage system.

• The wastewater comes into a storage tank, from where it is periodically pumped out by a sewage machine.

A septic tank is a complex structure consisting of a reservoir and a system of perforated drainage pipes, designed for the treatment of domestic wastewater from the sewerage system. As mentioned earlier, this structure consists of two parts:

• The first part of the septic tank is a reservoir, or receiving chamber, where wastewater from the house is supplied.
• The second part of the septic tank is a structure (field filtration or soil post-treatment) of perforated pipes laid on a layer of rubble.

The first part of the septic tank, or the receiving chamber, can be made of many materials, but we will talk about this in the next article. He will also tell you about all the pros and cons of these solutions with a septic tank.

VOC is a local treatment plant designed for mechanical and biological treatment of domestic wastewater from the sewage system. This structure is a multi-chamber closed system in which all steps and cycles of wastewater treatment take place. The whole complex of measures in VOCs allows to ensure complete and reliable treatment with a degree of 98%, which allows reuse of treated wastewater from VOCs. It can be used for watering plants, washing a car, or simply dumping into a ditch, storage tank or absorption well. True, it meets these criteria only after the installation reaches the operating mode (when the bacterial colony multiplies in sufficient quantity). This can take up to 2-3 weeks.

Since everyone has different situations and conditions on the site, first you need to know the following:

• GWL - groundwater level. GWL is the first underground aquifer from the earth's surface. It lies above the first waterproof layer, which does not allow water to pass through and does not allow it to penetrate deeper). But it should also be borne in mind that GWL is a constant phenomenon. First of all, it depends on the time of year. For example, in spring, snow melts at which the GWL increases, while in winter it decreases.
• The presence of water protection facilities / zones - a limited regime for the implementation of any activity is established on them. Which are aimed at preventing contamination and clogging.
• The area for a septic tank / moss is the size of the plot that you are ready to give for the organization of wastewater treatment.

IMPORTANT: Bacteria for the treatment of effluents in and

Why are they and why are we writing about them? Bacteria - bacteria they are everywhere and everywhere, but even here you cannot do without them. Let's take a closer look at what and how bacteria are formed in a septic tank or VOC for (all-season) permanent residence. It is important to understand not only the external structure, but also the internal processes. Correct operation and conditions for bacteria will ensure reliable operation of the VOC and septic tank for permanent residence. They play the most important role in the cleaning stages. Let's get to know them better ...

Anaerobic bacteria for and

Waste enters the septic tank, a reaction of their decomposition and the formation of bacteria occurs. They are formed and require a minimum concentration of air or an oxygen-free environment. It is recommended to choose septic tanks that are sealed and durable. It is advisable to look at the warranty and production method. The cleaning process with these bacteria is quite slow. It is also called anaerobic treatment or simply wastewater clarification.

As a result, after anaerobic treatment, wastewater is not allowed to be discharged into the ground or ditch, since it is not sufficiently treated and is not industrial water. To dispose of it, a storage tank is used, and in the case of additional cleaning, aeration fields are used / equipped.

Aerobic bacteria for

In they are formed in the aeration tank chamber. This is a special tank or structure located after the preliminary settling tank, in which anaerobic bacteria are formed. Pre-treated wastewater with activated sludge flows or is pumped into the aeration tank chamber, where deep biological treatment takes place. This process occurs due to the forced saturation of the effluents with oxygen. For the vital activity and reproduction of aerobic bacteria, a favorable environment is needed - oxygen-enriched water. This process consists in the separation of natural waste into components. This type of bacteria is the most effective because it quickly affects biological substances.

• For normal life, activated sludge organisms require small amounts of dissolved oxygen. The critical concentration is considered to be 0.2 mg / dm³, quite satisfactory - 0.5 mg / dm³ of dissolved oxygen.
• The maximum cleaning percentage for anaerobic bacteria is 60%.
• The maximum cleaning percentage for aerobic bacteria is 98%.

PRINCIPLE OF WORK or how it works:, or.

Since the process and principle of operation of the storage tank is already clear, let's take a closer look at how the processes and work occur in the septic tank and /. Wastewater through a pipeline or sewer enters a septic tank or. The principle of operation of all cleaning systems consists of several stages. The partial stage cannot provide the required cleaning quality and is not recommended by law and regulations for dumping into the ground. First of all, we will analyze the information about the septic tank ...

The septic tank is a "beta" version of the local sewage treatment plant. To begin with, how does the cleaning process take place in a septic tank.

• After the effluent enters the septic tank (tank), primary settling occurs with a minimum amount of oxygen. This stage is necessary to perform preliminary wastewater treatment. First of all, settling, fermentation and reproduction of anaerobic bacteria occur. As a result of the first stage, the heavy fractions settle to the bottom, the fat floats up and the effluents are clarified. After preliminary settling and all biological processes, the degree of purification is 60%.
• After the first stage, the degree of purification is not sufficient to safely discharge wastewater into the ground. It is not technical and does not comply with standards and regulations. The water needs additional treatment, for this event it is necessary to release the settled effluent to the soil additional treatment (filtration field). At this stage, wastewater gets the opportunity to form aerobic bacteria, passing through the soil and being cleaned of possible impurities. This event provides cleaning with a degree of 90%.

These cycles consist of several cleaning steps, which is why the container consists of several parts / compartments. The effluent from the sewage system ends up in VOCs, which mainly consist of 3 parts.

• First compartment or preliminary settling tank. It uses a mechanical / anaerobic cleaning method. Bacteria arise as a result of sedimentation and fermentation of wastewater in a septic tank and autonomous sewage system. Likewise - like the first stage in a septic tank. The effluent flows into the second compartment through a system of airlifts or by gravity.
• Second compartment or aerotank. A biological / aerobic cleaning method takes place in it. Aerobic bacteria arise and continue their vital activity as a result of the forced saturation of wastewater with oxygen, as a result of which biological decomposition of organic matter occurs. Pumps or compressors are used to form beneficial microorganisms. The effluent flows into the third compartment through a system of airlifts or by gravity.
• Third compartment or secondary sump. Here, the last stage of cleaning takes place - the remains of organic matter turn into silt and settle to the bottom. Industrial water with a degree of 98% purification comes out of the secondary chamber. This water is suitable for watering a vegetable garden or discharging into a river. Some septic tanks consist of only two chambers, so the degree of wastewater treatment in them is lower.

• Septic tank - purification degree 90%
• VOC - purification rate 98%

TO WHOM WHAT? how to choose OR OR

Let's take a closer look at the technical features and purposes for consumers. Most likely, after reading this block, you will understand exactly what you need for temporary residence, and what for (all-season) permanent residence. And the most important thing is that you will choose the best septic tank for your dacha and home, and maybe VOC.

Storage capacity

A storage tank is an ideal option for a small country house in which 2-3 people live, and even then not in all cases, since they do not process wastewater. First of all, this option is suitable for those who plan to live in a house or summer cottage seasonally: 2-3 months a year (summer). This option is the simplest of all solutions for the drainage of sewage. Taking into account the direct purpose of the storage tank, you need to select the most optimal volume of the tank.

Service

The service of storage tanks is only one and quite simple. To carry it out, it is necessary to call the waste water ossification machine and pump out the waste water from the storage tank when it is full.

First of all, a septic tank for a home with a filtration field is used on well-permeable soil. It does not require electricity and is popular for temporary and seasonal stays. If everything is properly organized and taken into account, it is an ideal option for summer cottages (all-season) for permanent residence. Of course, if it is possible to organize and install a septic tank with soil treatment (filtration field), taking into account the laws and regulations. As well as the Low level of groundwater, is the main factor in the choice of existing options for the disposal of treated wastewater. Minimum water table (min. 1.5 m from drainage pipes).

Filtration field

The main visual differences between the storage tank and the septic tank are the additional construction of the second stage of treatment.
The filtration field is an underground system of drainpipes located on a layer of gravel on which wastewater treatment takes place. The receiver of the treated wastewater is the soil. In the case of a high level of groundwater, a pumping station should be installed and the entire treatment facility should be placed higher and installed in an embankment.

At the moment, it is an ideal, practical and correct solution for a house, summer cottage or cottage for permanent and temporary residence. First of all, the installation of a deep biological treatment station requires a rather small amount of space compared to a septic tank or a storage tank. All biological treatment processes take place in one tank, there is no need to organize filtration fields and other technical solutions. You just need to divert the treated wastewater into the ground, ditch or water body.

Purification degree

VOC is a modern wastewater treatment plant with a high degree of purification of 98%. Thanks to all the processes and new technologies, MBBR can be applied and will be suitable for any area - size and condition. It is clear that there are situations when it is impossible to organize the discharge of treated wastewater. Filtration fields in the embankment are then applied. But these are unique cases that make it possible to organize the absorption of treated wastewater into the soil.

Facilities

Manufacturers immediately indicate the number of users in order to perfectly match the los to your needs. But it is necessary to correctly understand the processes inside the station, since some deep biological treatment stations require a constant flow of wastewater. Therefore, in VOC Delfin everything is realized by gravity.

For permanent or temporary residence - DIFFERENCES:, or.

All systems are designed to purify wastewater after a home or summer cottage, but it is necessary to understand not only the positive side, but also the negative in order to make the right decision. Below is a table that contains reviews, facts and technical features of the use of a particular cleaning system. A septic tank for permanent residence, according to its parameters, must fully cope with the estimated volume of flow, therefore, when buying, it is necessary to take into account how many people will live in the household. It is also worth noting that for temporary residence, you should pay attention to not expensive stations that require minimal financial costs. When it comes to a septic tank for a permanent stay, we recommend taking a deep cleaning station.

RATING: Description of top-end IMPORT (Finnish, Polish) and domestic Russian / for permanent residence

In this article, there will be a general comparison of existing autonomous sewers / VOCs on the territory of the Russian Federation. We will try to highlight the most popular autonomous sewerage systems produced in Russia or in Europe. Despite the fact that many different septic tanks are currently on the market, not all of them are of high quality and reliable. When choosing, it is also necessary to build on not only the characteristics, but also from the manufacturer's company. Comparing septic tanks for the house with each other, it is impossible to say definitely which one is the best, since each type has its own advantages and disadvantages. But in general, you can ...

Since there are currently many varieties of septic tanks on the construction market, which differ not only in varieties, technical characteristics, but also in prices, it is quite difficult to choose them. Therefore, it is worthwhile to clearly analyze all the nuances and choose it according to its technical characteristics, the quality of the cleaning device and parameters, as well as depending on its manufacturer.

Delfin

Deep biological cleaning process in autonomous sewage system DELFIN PRO / LOS occurs by gravity through all 3 chambers (preliminary settling tank, aeration tank, secondary settling tank) without stopping the recirculation. This ensures reliable performance in the event of a power outage of the VOC. European Reliable Autonomous Sewerage PRO continues to work on the principle of a three-chamber septic tank.

• VOC No flooding
• Stable work of effluents
• No unscheduled maintenance

Topas and Principle of operation

Is a sewage treatment plant built according to a four-chamber scheme. The transfer of purified water from one chamber to another does not occur by gravity, but with the help of an airlift, therefore the operation of the entire system depends on electricity. The power outage blocks the operation of the septic tank, which is a very significant drawback, outweighing the very deep wastewater treatment (almost 98%). The compressor ensures the operation of the septic tank, therefore the installation requires connection to the power supply. Therefore, it is worth planning the installation of such a septic tank only where the electricity supply is stable. If the compressor stops, the station will not be able to function.

Receiving chamber

Wastewater flows into the receiving chamber. In contrast to the "classical installations" in Topas, the receiving chamber is equipped with an aerator for mixing the effluent and saturating it with air oxygen. Aeration in the receiving chamber is switched on when the runoff level in it decreases to the operating minimum. Thanks to this, instead of sedimentation and decay of the sediment, the effluent in the receiving chamber is averaged in composition, and the purification processes begin - the decomposition of molecules of organic compounds occurs under the action of enzymes secreted by bacteria. Coarse filter The fine particles of contaminants mixed in the effluent passed through a filter with cells of 10 mm in diameter enter the main pump. Large particles of dirt and debris remain in the receiving chamber. The main pump is an airlift, in which the air supplied by the compressor (9) lifts the waste water through the pipe and pumps it to the aeration tank-reactor. The pumping takes place evenly with a low capacity and, unlike other types of pumps, without high consumption of electricity and voltage surges caused by starting the pump. Float switch To switch Topas operating modes, a float switch is installed in the receiving chamber. In the first phase, when the receiving chamber is filled with waste water, the float rises and the first compressor is turned on. It supplies compressed air to:

When the drain level in the receiving chamber drops to the operating minimum, the float is lowered and the second compressor is turned on. The air supply switches to:

• aeration of the receiving chamber,
• airlift for pumping sludge from the aeration tank to the stabilizing sump,
• airlift to remove the grease film in the secondary clarifier,
• aeration in the secondary sedimentation tank.

Aeration tank reactor

The chamber in which the main wastewater treatment with activated sludge microorganisms takes place. Due to aeration, the waste stream is kept in suspension and saturated with atmospheric oxygen. In the settling phase, the sludge begins to settle to the bottom and the sludge particles are combined into flakes. Due to a decrease in the amount of oxygen in the effluent, bacteria begin to use dissolved nitrogen compounds - nitrates for respiration, reducing them to nitrites and then to molecular nitrogen. Denitrification takes place - removal of nitrates and nitrites.

Secondary settling tank

A chamber in the form of a truncated inverted pyramid and located in an aerotank-reactor. Sludge settles in the sump, which returns to the aeration tank through the opening at the bottom. Additionally, the mixture of water and sludge is fed from the aeration tank-reactor into the secondary settler from above, using a recirculation airlift (6). This speeds up the process of sludge settling and water clarification. The film of light fractions (fats, oils) is stirred up by a bubbler in the upper layer of water and removed to the aerotank by an airlift built into the pyramid. Treated waste water is discharged outside by gravity through an outlet in the unit's casing or is collected in a forced discharge tank with a pump installed in it. Dying sludge settles most quickly on the bottom of the aeration tank-reactor, which, in the settling phase in the aeration tank, is pumped by means of an airlift (8) into the sludge stabilizing tank (D). This is the smallest chamber in which the accumulation and mineralization of sludge occurs. Through the existing opening in the upper part, the clarified sludge water flows back into the receiving chamber, thus closing the internal circulation process. A standard airlift pump for sludge pumping is installed in the stabilizer sump. This pump is muffled and the air supplied to it stirs up the sludge mass, preventing it from settling and compacting at the bottom. As part of self-service, a standard pump is used to pump out sludge; in order to avoid sludge compaction in the stabilizer, pumping must be done once a quarter. It is possible to pump out sludge 1-2 times a year (as part of maintenance) with a drainage (fecal) pump for contaminated water.

The principle of operation of the autonomous sewerage Alta Bio

At the heart of each autonomous sewage system for a summer residence is a septic tank, which is designed to purify water from harmful impurities. Most organic waste is decomposed in it. Today there are a large number of various autonomous sewers. Alta Group offers a more advanced design, which is a complete water purification system from waste.

Two stages of water purification in the autonomous sewage system Alta Bio:

The first stage of wastewater treatment is the sedimentation of suspended particles in a three-chamber sedimentation tank. The settling tank (the lower part of the Station) consists of 3 separate sections with overflows through which the wastewater from the domestic sewage system flows. Overflows are located so that wastewater flows at the lowest speed, due to which coarse suspended particles settle to the bottom in each chamber. The volume of the first section is 50%, and the second and third - 25% of the total volume of the settling tank. The total volume of the settling tank is designed for two-day waste processing.

Second stage of wastewater treatment

Post-treatment in a biofilter. From the third chamber of the settling tank, clarified wastewater is pumped into the upper part of the station by means of a drainage pump controlled by an electronic unit and through a rotating sprayer is evenly sprayed over the entire area of ​​the biofuel (biofilter). The filter is a habitat for microorganisms. At the moment of spraying, the waste water is saturated with oxygen and filtered through the feed material.

Autonomous sewerage for a private house Alta bio uses electricity in its work. However, even if it is turned off, the station will continue to operate normally, but already as a conventional septic tank. And when the power supply is resumed, the station will go into operation.

Brief description and scope of Alta Bio septic tank

The treatment plant in question is intended for use in private homes or public places with a small number of visitors. It can be used to equip the sewerage system in summer cottages, cottages or other types of suburban structures. Often, septic tanks are installed in country cafes, restaurants or snack bars.

The design and principle of operation of the septic tank Tver

The container is delimited by internal partitions, which form the following chambers:

• septic. Wastewaters get here in the first place, and it is here that the main processes of settling of insoluble suspensions take place. Over time, some of them pass into the soluble phase and are sent to the next purification stage;
• anaerobic bioreactor. The next chamber on the way of the sewage is the aeration tank. At the bottom of the aeration tank, an aerator is installed, through which air is supplied from a compressor installed in the house through a pipeline. Burnt expanded clay is poured onto the aerator, which does not float. A biofilm of microorganisms is formed on the expanded clay loading, which, together with activated sludge, absorb and oxidize pollution. In this chamber, the components of the effluents are mechanically destroyed during the passage through the structural elements of the chamber (ruffs) and are partially hydrolyzed due to the vital activity of anaerobic microorganisms (yeast) - the process takes place here fermentation of effluents;
• aerotank. In this chamber there is an aerator, due to the work of which the wastewater is saturated with oxygen. This, in turn, contributes to the intensification of the reproduction of aerobic microorganisms, which are always found in domestic wastewater as a natural microflora. The oxygenated liquid goes for further processing;
• sump. Before entering the aerobic bioreactor, the wastewater passes through the settling chamber, which retains heavy suspensions, which favorably affects the subsequent processes of biological decomposition of organic matter;
• aerobic bioreactor. In this chamber, two processes take place simultaneously: aerobic microbes actively multiply and absorb organic inclusions that make up the wastewater, and the limestone at the bottom of the section gradually dissolves in water and binds to phosphorus and nitrogen compounds, which are distinguished by high toxicity rates. In the aerobic bioreactor, as well as in the second chamber, there is a brush loading. The biofilm layer on the feed collects and oxidizes organic impurities remaining after deep cleaning. At the bottom of the bioreactor, a layer of crushed dolomite is placed, which gradually dissolves in waste water, which helps to remove phosvates from it due to their binding with calcium and magnesium ions. The final chamber is a tertiary sedimentation tank, where dead biofilm is retained, then wastewater is drained by gravity to the discharge point.
• sedimentation tank. In this chamber, the liquid is additionally clarified by natural precipitation of heavier inclusions, and only after that 95-98% purified water leaves the Tver septic tank. Additionally, floats with chlorine-containing reagents are installed in this chamber, which are responsible for water disinfection.

The septic tank has a small weight and rather thin walls, this cannot be attributed to the pros or cons. These factors allow for easy installation, and the thin walls are made of high quality polypropylene. Under the influence of heavy loads, they can bend, but will not collapse.

FINNISH SEPTIC UPONOR (Uponor)

WehoPuts local wastewater treatment plant is a biochemical type wastewater treatment plant for use throughout the year as a wastewater treatment system.

A local treatment plant for a country house or summer cottage WehoPuts 5 and WehoPuts 10 are designed to treat wastewater from one household. The model number means the number of people living. For the calculation, a daily water consumption of at least 150 liters per person is used. Both systems are designed for year-round use.

The range of Finnish local treatment facilities (septic tanks) Uponor Bio is represented by products of complete biochemical treatment of domestic wastewater. Those. after passing through such installations, the liquid can be drained without subsequent soil cleaning. The stations are volatile, moreover, for their normal functioning, it is necessary to use special floating (precipitating) additives. The principle of operation of such stations is as follows:

• wastewater flows by gravity into the receiving chamber (sump), where the bulk of light and heavy inclusions are retained. There are several sedimentation tanks, which allows you to get rid of obvious contamination as completely as possible;
• then the effluents enter the technological tank equipped with an aerator, in which the potential of activated sludge is used (microbiological processes are actively proceeding). Part of the sludge is periodically pumped out into the receiving chamber;
• at the next stage, a special reagent is dosed into the wastewater in portions, which promotes the precipitation of fine suspensions. He is also responsible for the binding of phosphorus compounds;
• after the entire cleaning cycle, the liquid can be discharged into the ground

Advantages of this system: wastewaters are processed in batches, which allows achieving the same treatment quality indicators; containers are strong and durable; the products are accompanied by all the necessary documents and are easy to operate. The disadvantages are the overpriced Uponor Bio septic tanks (compare, at least, with the cost of Tver or Topas septic tanks), the need to use additional reagents.

LOS Uponor BioClin is one of the innovative solutions from the Finnish manufacturer: compact, durable, easy to use, both in private houses and in summer cottages. Meets all sanitary requirements. Consists of a one-piece container in which the following processes take place:

• preliminary processes of rough wastewater treatment are taking place in the sump;
• in the next tank, the drains are aerated, inclusions are actively processed by aerobic microbes;
• then a floating reagent is added to the effluent (the process is the same as in Uponor Bio);
• excess activated sludge is pumped into the receiving chamber;
• treated wastewater is pumped into a sampling well

Astra Unilos. This is a well-known sewage treatment plant for cleaning the sewerage of a cottage, a private house or a whole group of houses. Given the relatively high cost of this model, consumers often discount the purchase of one powerful unit, which is mounted with the expectation of several families. Among the advantages: reliability of operation, high cleaning efficiency. Among the disadvantages: relatively slow operation, high price. The body of the septic tank is divided into four sections: a receiving compartment, an aeration tank, a sedimentation section and a system for discharging treated water into the external environment. Pumps and ventilation systems are attached to the septic tank, which are required for transferring water from one section to another and for aerating wastewater.

Receiving chamber or surge tank

Untreated wastewater through the sewer main (1,2) enters the receiving chamber (A) of the installation, where they are prepared - grinding and partial oxidation due to aeration - forced saturation of wastewater with oxygen from the air generated during the operation of the air installed in a special compartment (I) compressor. Then, uniformly mixed wastewater through a filter of coarse fractions, which prevents large mechanical and non-decomposable impurities from passing further, is pumped by the main pump into the aeration tank chamber (B).

Aeration tank

It should be noted that all pumps that pump between chambers in Unilos are made according to the principle of an airlift (or mamut pump), where pumping is due to the supply of air into a tube lowered into the pumped liquid. consisting of different types of microorganisms, which in the process of life decompose the substances that make up wastewater. The condition for the formation of activated sludge is the aeration process in the aeration tank chamber, which occurs in the direct (first) phase of operation.

Secondary settling tank

After the aeration tank, a mixture of treated effluents and activated sludge enters the next chamber - a secondary clarifier (C), where the sludge settles to the bottom under the action of gravity, and clarified purified wastewater, which is technically pure water, enters the outlet of the station (3). A grease trap (grease trap) is installed between the chambers of the aeration tank and the secondary sedimentation tank, which removes possible fat accumulations from the secondary sedimentation tank back to the aeration tank for further processing.

Sludge stabilizer

Sludge settled on the common bottom of the aeration tank and secondary clarifier chambers is pumped out into the sludge stabilizer (D), where it also settles to the bottom, gradually accumulating until it is removed. To maintain a high degree of purification, a level sensor (float switch) is installed in the receiving chamber, which regulates the switching of aeration modes in the aeration tank and the receiving chamber, depending on the level of effluents in the latter.

How Eurobion works

The operation of the Eurobion station is based on the biochemical method of wastewater treatment, which consists in the ability of microorganisms, in the presence or temporary absence of dissolved oxygen, to use wastewater pollutants as food. Below is the flow chart of the Eurobion deep biological treatment station.

Receiving aeration tank

The effluent flows through the inlet sewer pipe (1) into the receiving aeration tank (2) in which, with the help of the POLYATR aeration element (3) and the operation of the compressor (19), the process of saturation of wastewater with atmospheric oxygen takes place - aeration. In the presence of dissolved oxygen, effluents are mixed with activated sludge - the biomass of microorganisms that process pollutants.

Primary aerobic sump

Partially treated wastewater passes through two openings in the intermediate bottom (4) and enters the upper zone of the primary aerobic clarifier (5). This zone is characterized by a high concentration of activated sludge and a minimum level of dissolved oxygen. Under these conditions, the denitrification process is intense, which is the destruction of nitric acid salts (nitrates) to molecular nitrogen. Further, the wastewater as it moves downward falls into the zone of aerobic sludge, where the processes of self-oxidation and decomposition of difficult-to-process contaminants take place. Part of the activated sludge through the overflow (6) enters the lower part of the secondary clarifier (10).

Secondary settling tank

The sludge settles to the bottom of the secondary clarifier and returns to the aeration zone with a recirculation pump (9), i.e. to the beginning of the technological chain. The process is repeated until the effect of deep biological cleaning is achieved. The biofilm that forms during the purification process in the secondary clarifier enters the biofilm degasser (14) and under the action of bubbling is destroyed in the vertical pipe of the degasser (11). Clarified effluents enter a tertiary settling tank installed directly in front of the AEROSLIV outlet dispenser (12), the task of which is to regulate the flow rate of the treated effluent to the outlet of the unit. Treated wastewater to the level of technically pure water is discharged by gravity through the pipe (13) outside the installation, or it enters the storage tank and is already pumped out from there by a drainage pump, in case of compulsory execution of the station.

AU BIOTANK

This series has established itself as absolutely unpretentious in operation and practically maintenance-free deep biological wastewater treatment plant. Does not require additional treatment in the ground. The advantages of this system: no additional treatment fields, no complex electronics, no operational problems, quick access to the mode, not afraid of a temporary power outage, the output is clean, odorless water.

The most modern deep biological treatment plant BIOTANK, developed by Triton Plastic, is produced in four modifications.

Firstly, the separation of septic tanks is according to the shape of the body, vertical and horizontal... Vertical BIOTANK is intended for installation in small areas, because it requires a narrow but deep pit. Accordingly, the horizontal BIOTANK, consisting of universal buildings, which allows you to build a septic tank for any volume and capacity, is installed where there is no restriction on the area of ​​the pit.

For each of the two cases, modifications are also provided. with gravity discharge of water, and with forced reset to the relief using a pump. These series are marked as - MYSELF and NS.

For the manufacture of the case, a modern polymer material is used. Inside, a polypropylene insert made by molding is used to divide the container into compartments. Tasks of each of the compartments: The first, as in other septic tanks, serves as a receiver and settler for separating undissolved inclusions. The second compartment is equipped with an aerobic nitrifier with a floating load covered with biofilm. In this compartment, the main cleaning process takes place, that is, the processes of oxidation of organic impurities and ammonium nitrogen. To ensure the flow of chemical reactions, air is supplied to the chamber. The next chamber serves as an additional sedimentation tank, in which the medium is separated, the water is freed from the residues that formed during the cleaning process. The last compartment is a biofilter chamber that functions like a separator. Pure water (98% purified) is supplied to the outlet.

ATTENTION THERE ARE SUCH AUTONOMOUS SEWERS in 2018

• Requiring an accurate calculation of station performance. There is a risk of a decrease in the degree of purification if there are more or less users, but not all autonomous sewers are accurately calculated.
• In the event of a power outage, most stations, due to their design features, lose the ability to continue treatment and the degree of general wastewater treatment tends to 0%.
• The design of many autonomous sewerage systems requires frequent and periodic maintenance, repair and replacement of station components.
• A long break in the use of the station is not allowed if it is not equipped with automatic circulation of waste water and activated sludge.
• The dimensions of the receiving chambers in some autonomous sewers are not designed for large household waste. Also, a volley discharge (drainage of the bath and the simultaneous use of the entire sewage system) can disrupt the processes in the preliminary sedimentation tank, which will lead to a decrease in the degree of wastewater treatment. volume poorly copes with large household waste and salvo discharge.

Basic parameters when choosing

Since all residential stations are designed and built to provide wastewater treatment, we need the dry facts to make the best possible comparison and provide you with a winner. It won't be so easy, as each station has its own flavor. And how much it has a positive effect, we will tell you a little later. We compare the parameters and properties of deep biological treatment plants so that you get the result you expect. Facts and logic will be our guides in comparing all autonomous sewers. A high-quality septic tank or salmon with a big guarantee is a guarantee of quality and your peace of mind.

not susceptible to chemicals, hair and small debris

Oddly enough, there are also such stations at which there is a direct restriction on discharge into the autonomous sewage system. It is clear that the station is not a trash can, but we will take into account how these problems were solved. In some, they are completely excluded in order to maximally compare with the central sewage system, but in others, unfortunately, having design limitations, this problem has not been solved. Below is a brief comparison and description of how the problem was resolved.

location of the controller

The stable operation of electrical appliances depends on many environmental factors. Ambient temperature, sharp changes in it, humidity create a dew point, which can be critical. They affect the service life of electrical equipment, worsen their working conditions, cause accidents, damage and even destruction of the entire installation. The electrical properties of insulating materials are especially dependent on environmental conditions, without which no electrical device can do. Under the influence of climate and even weather changes, these materials can quickly and significantly change, and under critical circumstances, lose their electrical insulating properties. The influence of unfavorable environmental factors on electrical equipment must be taken into account in the design, installation and operation of electrical installations.

The energy consumption of an autonomous sewage system depends on

• Working hours
• Power of devices and equipment

guarantee

When buying a product or receiving any services, we always want to be sure that we will not be left alone with the purchased product. Care must be taken not to be mistaken in marketing moves, such as a service life of more than 1000 years, when the official warranty is only 1 year. Therefore, in this heading, we would like to simply rank the companies in descending order of the guarantee they can provide to their client. This is necessary: ​​to make repairs and replacement of parts free of charge. This parameter guarantees you peace of mind and reliability for many years, during which you can contact the seller in case of a malfunction or loss of product quality, such as:

• breaking
• poor quality material
• defective parts, etc.

Regarding autonomous sewerage, some manufacturers offer pumps, 2 compressors, controllers, ruffs, etc. Others use the laws of physics and gravity.

Living in a dacha allows you not only to take a break from the bustle of the city, but also to enjoy nature, clean air, and find peace. But so that nothing interferes with a good rest, you have to take care of the arrangement of the benefits of civilization - water supply, electricity and sewerage, isn't it?

Are you trying to figure out how to choose a septic tank for a summer residence, so as not to overpay and not miscalculate? We will help you in this matter - our article discusses the types of septic tanks, their structural and functional differences. Indeed, in order to choose the optimal utilizer, it is advisable to get acquainted with the existing options.

Sewerage equipment manufacturers offer a variety of options designed to facilitate suburban life.

Among the equipment options there are both simple and inexpensive models, and rather complex biological wastewater treatment plants.

It is rather difficult to choose one thing, especially if the owner of the cottage is faced with this issue for the first time.

Image gallery

It is enough to look at any catalog of an online store that offers septic tanks for a country house or summer cottage, and you have to face the difficult task of choosing. In fact, along with dealers in this area, there are enterprises that have only recently entered the market, or successful manufacturers that have been working for a long time and have won success, but decided to develop a new direction of their activities. Therefore, we suggest that you familiarize yourself with what septic tanks are for summer cottages and give a comparison so that you can decide which is better.

Septic tanks for summer cottages: which is better? What to consider when choosing them?

The model line of septic tanks is quite wide, which allows you to choose the best septic tank for a summer residence, which will meet individual requirements. When choosing such a cleaning system for a country house, cottage or summer cottage, you need to consider the following factors:

• The number of permanently residing people (also include possible guests).
• The number of plumbing points (showers, toilets, jacuzzis, baths, sinks) and household appliances (dishwashers and washing machines), the volume of their drains.
• Depth of groundwater.
• The type of soil on the site.
• The option of discharging treated water (gravity or forced).

How is the installation of a septic tank in the country going:

• Preparation of the pit.

• Arrangement of supply trenches for pipes and wires.

• Installing a septic tank in the pit and sprinkling with sand around.

• Filling the chambers of the septic tank with water.

• The pipe is cut, the power supply is connected.

• Commissioning works are in progress.

• The outer part of the septic tank is being prepared, taking into account the peculiarities of landscape design on the territory.

The principle of operation of septic tanks

A septic tank is a facility that is used to treat wastewater. The scheme of its device implies the presence of a multi-chamber system. Wastewater is piped from the house to the first tank (sump). Bacterial decomposition of effluents takes place in it. In some devices, usually of industrial production, structures are installed here that are responsible for filtering polluted water.

The decomposition of effluents occurs under the influence of anaerobic or anoxic bacteria. They convert the liquid entering the sump into clarified water, gas and mineral insoluble sludge or sludge.

The gas formed as a result of the decomposition of wastewater is discharged through the ventilation pipe, and the water goes into the overflow hole in the second tank. In this case, the anaerobic bacteria do not stop cleaning the effluent. Then the clarified water enters the next container or is fed to the filtration fields. After soil filtration, the liquid is absorbed into the soil. This structure belongs to the systems of the anaerobic type or non-volatile septic tanks.

There is also a variety of devices that require electricity to operate. These are aerobic septic tanks with biological treatment. In such devices, wastewater treatment is carried out by aerobic microorganisms, which simply cannot exist without oxygen. For this reason, the compressor automatically turns on after a certain time, supplies air to the tanks. The effluent decomposition process in these plants is very fast. The level of purification of polluted waters is 98%.

The principle of operation of an aerobic septic tank requires a constant flow of oxygen, since the bacteria contained in the activated sludge die and the cleaning stops.

Among the most common structures is a storage septic tank. It is a single-chamber sealed device used to accumulate wastewater as a result of being pumped out by a sewer truck. Additionally, the tank is equipped with a fill level sensor. This option is the best for those who often appear in a country house, and for various reasons it is impossible to equip an effective wastewater treatment site.

Septic tanks for summer cottages: which is better?

1. Non-volatile septic tanks.

Models that work without electricity and are not tied to the presence of power grids are suitable for small country houses. In remote areas and garden partnerships, there is a possibility of a power outage for a sufficiently long period, so it is worthwhile to decide in advance on the equipment for small country houses. In remote areas and garden partnerships, there is a risk of power deviation for a sufficiently long period, so it is worth choosing equipment for sewage in advance.

Of course, users have a question whether a septic tank is needed at all in the country, if it is possible to equip a cesspool. We will not overpersuade the owners of summer cottages, but simply remind them of aesthetics, sanitary requirements and basic amenities. We suggest that you familiarize yourself with the best non-volatile septic tanks.

• "Tank".

The septic tank "Tank" is made of high-strength plastic with a thickness of 10 to 17 mm with stiffening ribs. The design itself provides for resistance to high loads that are formed under soil pressure in summer and winter. The estimated service life of the product is at least five to ten years, subject to the operating conditions. A conventional septic tank works on the principle of wastewater treatment by sedimentation or further biological decomposition of the material with a biofilter, which has a high performance. The infiltrator is responsible for the distribution of treated water that enters the ground.

The unique shape of the body protects the structure of the septic tank from being squeezed out by the soil, and the possibility of equipping with a high neck allows them to be placed at the required depth. A special design, including block-modules, allows you to collect almost any volume of a septic tank, and overflow pipes act as connections.

The operating conditions of the septic tank imply its periodic cleaning from the accumulated solid residue. With proper operation of the equipment and the use of bacterial colonies, the container is cleaned every four to five years. But it is recommended to do this at least once a year. In the case of periodic use of a septic tank, for the winter, when it is not supposed to purify wastewater for sewage, about a third of the water is removed from the tank.

Table of characteristics of the septic tank "Tank"

The price of a septic tank "Tank"

It is worth noting that the price of this septic tank is more than affordable for many private home owners. This is one of the main advantages that arouses great interest in the product. The price largely depends on its volume and therefore increases with the increase in capacity.

Reviews about the septic tank "Tank" for giving

Alexander

“The septic tank filters perfectly, there are no comments. There were no problems with its installation, since everything is detailed in the instructions. Convenient, environmentally friendly, economical. I leave your positive feedback. "

"I studied many reviews, the opinions of buyers differ, but, as a rule, negative emotions arise only due to improper installation and operation of this septic tank."

"The septic tank does not consume electricity and works completely autonomously, but I would not take a very large volume, as unfavorable conditions for the development of bacteria can form."

“Two years ago, a septic tank“ Tank-1 ”was installed, from which we use water to irrigate the garden. It is very convenient, since there is no water source on our site, including technical one. "

• "Triton".

Three chambers, which are responsible for the implementation of the process of removing various suspensions from contaminated water, anaerobic decomposition of biological material, as well as supplying treated effluents to a special filtration platform. This septic tank is produced in several versions, which makes it possible to choose between models having a volume of 2 to 40 m 3.

Once a year, or in the case of intensive use twice a year, it is worth cleaning the container from the accumulated solid sediment. The service life of the plastic container is approximately 50 years. When installing the equipment, it is necessary to provide for an "anchor", a monolithic concrete surface or a concrete slab, which ensures good retention of the septic tank at the required level.

For small baths and country houses, it is better to use the Triton-mini models, which are compact septic tanks for the summer, designed to receive small volumes of wastewater.

Table of characteristics of the septic tank "Triton"

The price of the septic tank "Triton"

Despite the low cost, treatment plants are popular both for small summer cottages and for country cottages for permanent residence. The septic tank provides the required level of wastewater treatment.

“Last summer I installed a septic tank“ Triton N- “1 at my dacha. Works perfectly well, fully copes with the declared function. "

Easy installation, low cost, simple maintenance. The quality and cost are fully justified. My parents installed such a septic tank last summer and were very happy. The first cleaning was quick, without unpleasant odors. "

“I installed this septic tank for my parents at their dacha in the village. They have been using it for three years, the father is happy. An excellent option for a summer residence, where there is a small amount of drainage water. "

“If installed correctly, the Triton septic tank is not afraid of severe frosts or other typical problems. Already two years have passed since the installation of the septic tank, everyone is happy. The guests who came to our dacha also seriously thought about installing such a septic tank. "

• "Aqua-bio".

The septic tank is intended for a summer cottage, where you can create a filtration field or other type of soil purification of water discharged from the tank. A simple septic tank system consists of passing contaminated water through 5 chambers. Initially, solid suspensions are deposited in 3 compartments of the tank, then in the remaining 2 chambers, the processes of anaerobic decomposition of organic matter take place due to the development of anaerobic colonies on the surface of a special load.

The main advantages of this septic tank are a large number of chambers, which increases the efficiency of wastewater treatment. As a result, you will not need to reconstruct the filtration fields, which will be clean for a long time, which means you will not face additional costs during the operation of the septic tank. The tightness of the robust plastic housing eliminates the possibility of contaminated wastewater entering the soil.

The performance of different models can vary from 600 to 1300 liters per day. It is on this indicator that the price of a septic tank for a summer residence depends. A simple calculation allows you to determine the most suitable model, but do not forget that such a septic tank is not suitable for an area where there is a high level of groundwater.

The models of the septic tank "Aqua-bio" differ from each other in performance and volumes. Today, containers are produced with a volume of 3600, 3000, 2500, 2000 liters. Accordingly, with a capacity of l / day: 1300, 1100, 900, 700.

Prices for septic tank "Aqua-bio"

If we talk about the cost of the septic tank "Aqua", then, in comparison with similar solutions, such structures cannot be classified as budgetary. You can be convinced of this by carefully studying the table below.

Reviews about the septic tank "Aqua-bio"

“I am not disappointed, it works reliably and stably. In severe frost, I once "caught" three centimeters of ice. I had to resort to insulating the covers. "

“I ordered, installed and operated for several years now. Everything is fine, I can say with confidence that he is not afraid of even severe frosts. "

"I have done a thorough installation, we had a good winter, I leave a positive review and recommend this septic tank for a summer residence."

1. Volatile septic tanks.

They need a constant connection to electricity, they can work on the principle of forced oxygen supply to the batteries, namely, aerobic wastewater treatment. Such models of a septic tank are a real deep cleaning station that allows you to bring it to the required level, when the drain can be directed to storm sewers, reservoirs and ditches without any risk of disrupting the ecological balance. Among domestic septic tanks, it is worth highlighting the five most common models.

• "Tver".

Such a septic tank belongs to the local treatment facilities, where wastewater treatment takes place in an integrated manner. The device uses several different technologies at the same time, which are combined into a single system and provide excellent results when using a small area of ​​land.

It should be noted right away that such a solution is volatile and adapted for use in homes intended for permanent residence. But it is also great for giving, if simple conservation rules are followed.

The equipment contains a multi-chamber container and high-quality plastic. The first chamber acts as a settling tank that retains most of the sparingly soluble impurities. Some of them will sink to the bottom, while the rest will float on the surface. Anaerobic decomposition processes take place here, continuing in the second chamber on biofolters. Then comes the aerotank chamber, where the water is saturated with oxygen. This activates aerobic water purification by microorganisms. The liquid is further purified in several chambers, where it flows by gravity. One of them contains a limestone load, where it binds to harmful decomposition products, namely nitrogen and phosphorus compounds.

The addition of chlorine-containing reagents increases the efficiency of water disinfection.

The installation of models is carried out on different types of soil, even if the cottage is located in former peat mines, which are characterized by an increased aggressive environment. Durable plastic does not corrode, and an additional "anchor" pre-installed in the pit will not allow the container to "float".

The main distinguishing feature of the Tver septic tank is the intake of a large volume of waste water. Therefore, if you need to drain the bath, then he will cope with this task without deteriorating the quality of the outlet water and without the release of untreated wastewater.

Table of characteristics of the septic tank "Tver"

Reviews and price of the septic tank "Tver"

If you look at all the reviews about these products, you can come to a single conclusion: such a treatment plant in most cases fully meets the needs of every modern person. There were no complaints about difficulty during operation or cleaning. It is good news that this septic tank is the development of our specialists. At the same time, the price for it is affordable, of which you will be convinced by studying the information in our table.

• "Leader".

These septic tanks use electricity to remove sediment from sedimentation tanks and to start an aerator that saturates the water with oxygen for the development of aerobic microorganisms that eat organic matter. As you can see, this is a volatile solution. Due to an integrated approach and the presence of six chambers, the process requires the use of special bio-additives, and the system is highly resistant to temporary overloads due to sewage pollution.

Wastewater treatment is carried out on such a principle that the discharge can be carried out in a convenient place: ditches, a reservoir or a drain well. As you can see, there are no violations of the norms for the discharge of pollutants, there is full consistency with the ecology of the surrounding nature.

Local wastewater treatment is carried out according to the principle of passing through all stages of the tank with pumping out of the activated sludge that has accumulated. The first chamber is used for the mechanical treatment stage - primary clarification of water and sedimentation of suspended particles. The manufacturer indicates that the efficiency of this chamber is 2/3 of mineral impurities.

As for the second stage, a bioreactor is used here, in which anaerobic bacteria initiate fermentation (conversion of substances that are difficult to oxidize into substances that are easy for the oxidation process). Moreover, bacteria develop on a polymer line that mimics algae. In the subsequent blocks of the septic tank, namely in the third, fourth and fifth, wastewater is purified by aerobic bacteria. All the conditions for life are provided for them, which are created with the help of two aeration tanks with aerators.

The bacteria themselves multiply on the porous material, form entire colonies, turning into activated sludge. As a result of the victorious battle with the drains, the last stage of the septic tank emerges. Here, phosphates are neutralized in an alkaline environment.

Price for septic tank Leader

The cost of a septic tank with turnkey installation directly depends on its size, power, weight, as well as connection to the sewage system. Also, septic tanks differ in price, which depends on the selected model of the purification device.

Nowadays, the price of a septic tank "Leader" may differ, so below we will understand not just the price category, but also in different models of the septic tank.

• "Poplar".

The design of this septic tank allows it to be used in the following temperature range - from -30 to +40 0С. It works on the principle of the passage of sewage water through four compartments (two of them are equipped with aerators). Regular supply of oxygen to the contents has a positive effect on the development of bacteria, which are responsible for the decomposition of biomaterial. The required oxygen pressure is provided by compressors, and the process of fluid circulation between different compartments is carried out by airlifts.

When human waste is decomposed by bacteria, wastewater flows into a sump, where activated sludge settles, and the liquid is sent through a filter to a collection system. All pumps are located in a sealed compartment, as a result of which the ingress of moisture on the contacts is completely excluded and reliable equipment protection is provided.

The body of the septic tank is made of polymers that do not corrode, and the average life of the septic tank is approximately 50 years. As for the deposits, they are removed independently or with the help of a sewage machine.

Table of characteristics of the septic tank "Topol"

Septic tank "Topol": reviews and prices

If the installation work is carried out in strict accordance with all the requirements, then no questions will arise during the operation of the Topol septic tank. We got acquainted with the numerous reviews on the operation of this treatment plant, which we could find on the Internet, and came to the following conclusion: the reviews are mostly positive, without harsh criticism of the septic tank and its characteristics. The main thing is to choose an installation that is appropriate in terms of performance and carry out its correct installation.

If we talk about prices, then they are competitive, neither cheaper nor more expensive than other options. Of course, they grow as capacity and capacity increase. In the table below, you can get acquainted with the average cost of the installation "Topol" of various capacities.

• "Topas".

In the septic tank "Topas" sewage water treatment is carried out in several directions: the process of decomposition of organic materials, reduction of salinity of wastewater, as well as cleaning from mechanical impurities. The principle of operation of such a septic tank cannot be considered innovative, but be that as it may, it provides purified water (98%), which you can use for irrigation.

The first stage of cleaning is carried out in the receiving chamber, in which the sedimentation of mechanical impurities takes place. Then the airlift is pumped partially purified water into the aeration tank to resolve organic compounds as a result of the vital activity of bacteria (their colonies are in activated sludge). Sludge suspensions entering with water have a deeper purification, which is deposited in the next compartment. Then completely purified water will be removed from the system, and the sludge is returned for subsequent use.

Service maintenance of the equipment occurs when checking the operation of the compressor and diagnosing the septic tank.

Table of characteristics "Topas"

Can't connect to the central sewerage system? You can solve the problem locally - install a septic tank. To simplify this task, we have prepared a review of 9 reliable septic tank manufacturers. Chances are good that other companies you come across are either copying the products of these 9 or counterfeiting.

We warn you! Hereinafter, by septic tanks, we mean any engineering structures intended for the collection or processing of wastewater, unless otherwise indicated. This includes VOC and SBO - local treatment facilities and biological treatment plants, respectively.

Instructions for the selection and installation of VOCs

Purpose of the article: tell about the most reliable companies that have been producing septic tanks and biological treatment plants for household waste for more than 10 years. Simplify the selection of the right equipment model based on the buyer's needs, site soil conditions and purchase budget.

Types of septic tanks

Before talking about sewage treatment plants, we will conduct a small educational program. Conventionally, all treatment facilities can be divided into 3 groups:

• storage tanks... It doesn't matter what they will be made of, their function is the same - to accumulate wastewater in itself before the arrival of the sewage truck. Relatively cheap, easy to install, maintenance-free. The use is limited by the useful volume of the tank, hence the need for economical use of water and linking to the services of sewers. It is inconvenient and expensive. They are used only when soil and other conditions do not allow the installation of structures from the following two groups;
• sedimentation tanks... Multi-section tanks that do not require an electrical connection for settling waste water and their anaerobic purification. Microbiological cleaning processes proceed slowly in an oxygen-depleted environment. The outlet water has a characteristic odor and is purified by a maximum of 60%, so it must be further purified. For this, fields or filtration wells are used: wastewater seeps through the soil layer, after which it does not pose a threat to the environment. The sedimentation tanks are simple and affordable, but demanding to maintain. They must be periodically cleaned of the accumulated sediment, and the filtration field must be redone every 5 years. This solution is not suitable for a high groundwater table (GWL) and soil with poor flow capacity, for example, clay;
• aeration stations. The most advanced systems for preparing households. drains. In the process of settling, aeration and the use of microorganisms, the drains are cleared by more than 90%, have no odor, they can be drained into roadside ditches. However, such stations require connection to the mains, their efficiency suffers during power outages. Plus, they are expensive and need qualified service.

We figured out the types of treatment facilities. It remains to take 5 steps to choose the one that suits your particular operating conditions.

We hope this table helped you choose the appropriate septic tank option. It remains to decide on the manufacturer. In the table below there are 9 companies and their brief characteristics. All the manufacturers we reviewed offer solutions for both seasonal and permanent residence.

1. "Aqua Hold" - septic tanks Bars

at a price of 54 900 rubles.

2. "Topol-EKO" - treatment facilities Topas

at a price of 89 900 rubles.

The manufacturer's catalog contains both individual treatment plants for private houses and complex and specialized solutions for a group of houses, villages and enterprises. There are also other plastic products: cellars, decorative stones, contact tanks, electroplating baths, etc.

The company produces VOCs, which are in 3 large groups:

• For private houses. Topbio - non-volatile septic tanks for installation in sandy soils. Topas and Topas-S are stations with two or one compressor, respectively. Topaero - treatment facilities with protection against increased volley discharge of wastewater.
• For businesses and villages. Topglobal is a complex of equipment with containers made of reinforced concrete for cleaning households. and industrial effluents. Topaero-M is a collection of VOCs with increased total productivity for the treatment of domestic wastewater. Topaero-M / E is an analogue of the previous version for any type of wastewater.
• Specialized stations. Toplos-FL - for wastewater treatment from organic matter. Cyclone is a system for post-treatment of household waste water. Toplos-KM is a container-type VOC for households. drains. Toppolyum - separator of fats from catering establishments. Toprain - storm water treatment plant.

The presented equipment covers a wide range of performance. The youngest models are designed for 4 people, the oldest - up to 200. The use of active forced aeration guarantees the purification of domestic wastewater by 98%. Therefore, the company positions its SBO as a wastewater treatment plant that does not require a call for a sewer truck.

In most cases, polypropylene sheets with a thickness of 8 to 20 mm are used as the main material. The rigidity of the structure is achieved by using internal partitions and lattice structures as stiffeners.

* you can choose a modification with a built-in pump for forced pumping of treated wastewater. Larger performance models are available with an extended neck for recessed installation of the station when it is far from home, as well as reinforced versions for difficult soils.

Output: The main part of Topol-Eco products, which can be used in a private house or in a summer cottage, are energy-dependent biological treatment plants. They are made according to the most advanced technology to date, which is why they are more expensive than conventional septic tanks with a filtration field. But you also need to take into account that such equipment requires qualified maintenance, does not tolerate prolonged power outages and is designed for constant use.

These are 3-chamber tanks with the possibility of increasing the stages of wastewater treatment by adding additional blocks;
• biological purification systems. Volatile VOCs Biotank (4-10 people) and Eurobion (4-150 people) from HDPE and polypropylene, respectively.

The main material for the manufacture of containers is HDPE. Material thickness ranges from 10 to 15 mm, depending on model and location. For example, it is higher for stiffeners, and less for straight lines or areas of small curvature.

The video below clearly demonstrates the production of models from the HDPE Tank line. The plant is equipped with modern equipment, plastic sheets are supplied from Russian, Czech and German manufacturers.

* This is a model with gravity drainage of treated effluents. There is a modification with an installed pump for forced discharge. There is also a horizontal version.

** The infiltrator looks like an inverted plastic tub, it serves as the boundary of the treated wastewater filtration area.

Conclusions: although this manufacturer has different types of models, it is better known for its sedimentation tanks. The Tank series line is ideal for summer cottages and, in certain cases, can be used for permanent residence. In production, HDPE with a thickness of 10-15 mm is used, which is not always enough to ensure the rigidity of the structure when installed in complex soils.

5. "Multplast" - septic tanks Termit

at a price of 25,000 rubles.

The company "Multplast" specializes in the production of products from polyethylene and fiberglass: septic tanks, caissons, wells, etc. This manufacturer is known for the Termit and Ergobox product lines.

There are also accumulative models with a capacity of up to 5.5 cubic meters;
• biological treatment stations. Produced under the Ergobox brand. They are modifications of the Transformer (PR) models in which the compressor and aerators are installed.

All these products are made by rotational molding from Korean-made HDPE. The result is a strong seamless construction with well-developed stiffening ribs. The wall thickness is 20 mm.

* S - gravity. There is a PR modification with a pump for forced pumping of treated effluents. It costs 6 thousand rubles. more expensive than the gravity version.

Video demonstrating the installation process of the septic tank Termit. From a small video, you will also learn about what diameter the supply pipe should be, whether it can have 90-degree turns, how and where to drain the treated wastewater, etc.

Conclusions: it is easy to notice the similarity of the products from "Multplast" with the products of the Tank type. All the same pronounced stiffening ribs and simple design. Versions with a compressor may be of particular interest - a simple modification gives the design special properties. However, it should be borne in mind that a small number of chambers can lead to a low quality of wastewater treatment and, as a result, the need for a field or filtration well for additional treatment.

Conclusions: TD "Engineering Equipment" does not offer a large selection of systems for country houses. The guys just developed a model that works well and scaled it up. The result is not the most compact water treatment plant at an average price. The main thing is to make it work, isn't it?

Editor's Choice

All the manufacturers presented are good, but we especially want to highlight the following:

• "Aqua Hold". For septic tanks Leopard: a wide range of models of different types, the durable body of which is made of HDPE 25 mm thick. You can choose a treatment plant for any conditions. There are solutions for summer cottages, for permanent residence, for low and high ground level, various types of soil. The prices for the products are average for the market.
The only question is, to what extent their capabilities are implemented in a particular design of a septic tank. For example, there may be a container made of polypropylene, in which the seams are poorly welded, respectively, it will leak after some time.

The rigidity of the structure is influenced by the thickness of the material and the presence of structural elements: stiffeners and internal partitions. Therefore, if the design is unsuccessful or simply does not fit the specific operating conditions, the septic tank can flatten or break with soil. But the point is not in the quality of the material from which it is made, but in the design itself.

I cannot decide on the choice between a non-volatile septic tank and a biological treatment station with aerators. What's better?

If for a summer residence, choose a non-volatile sump, provided that the groundwater level is below 1.5 meters, and the soil itself has good filtering capabilities. For example, it is sand or sandy loam. Once a season, you will have to do dirty work and remove accumulated sludge from the bottom of the tank, but in general, such a solution is the most economically feasible and convenient for seasonal living.

For private houses, it is better to buy a system that ensures the maximum purity of the effluent at the outlet of the treatment plant. You can't do without a station with aerators. From the pros: the drains after it do not smell, they are so clean that they can be drained into roadside ditches. However, such a solution is more expensive, and automation and compressors require an electrical connection.

Summer cottage next to the forest, seasonal accommodation, four people. Advise a septic tank.

If you need cheaper and easier, then consider the Termit Profi 2.0 option. It is very similar to the well-known Tank, but it costs only 39,000 rubles. Also, the manufacturer often has promotions - you can save several thousand.

The filtration field can be set up next to the forest. There you will dispose of wastewater for additional treatment. So you will bring a minimum of inconvenience to yourself and your neighbors.

At the summer cottage there is a well, from where the water is used for food purposes. Which septic tank to choose?

Obviously, a treatment station is required here, after which the effluent can be discharged into a roadside ditch. If there is no ditch, it can be lowered into the ground, provided that the discharge point should be 50 m from the well.

If the soil does not accept water, then in some cases it makes sense to think about installing a storage tank with the subsequent call of the sewers.

Will the drains freeze in winter? Do I need to insulate a septic tank?

If used constantly, they will definitely not freeze - a kind of bioreactor constantly works inside that releases heat. In extreme cases, you can insulate it by sprinkling a layer of straw or leaves on top.

For seasonal use, it is recommended to fill the container 2/3 with drains, additionally insulating it from above. So the container will not float up and will not be crushed by the frozen soil. We recommend that you additionally read the instructions for a particular model, the manufacturer may have a different opinion on this matter.

What will happen to a volatile water treatment plant if the electricity is cut off?

Typically such systems are very sensitive to power outages. The air compressor stops working, and after 6 hours the amount of oxygen in the effluent is significantly reduced. A struggle begins between aerobes and anaerobes. The drains can begin to ferment due to anaerobes, therefore, after turning on the electricity, the return to normal operation occurs within several days.

Is there a strong odor from the septic tank?

After an ordinary sump there is a strong characteristic sewer odor. It can even be felt next to the filtration field, so they are equipped in the most distant place.

After systems with aeration, the water is cleaner and does not smell. Unless the operating mode of the station will be violated: exceeding the permissible peak discharge, power outages, the use of aggressive detergents.

Installed a septic tank with a filtration field without connecting to the power supply. How to serve it?

Every six months it is necessary to open the container and check the amount of sediment. If it is more than 1/5 of the height of the container, you will have to remove it. Use a bucket or fecal pump for this purpose.

Light fractions will accumulate on the surface of the effluent. If they form a thick solid layer with a thickness of more than 5 cm, it is also better to remove it in a timely manner, because later it can significantly complicate the cleaning of the tank.

Not every owner of a private house has the opportunity to connect to the central sewerage system. In this case, people get out of the situation by arranging local wastewater disposal and treatment systems. A septic tank will be a good helper in this matter, and there are quite a few varieties of these structures.

When choosing such products, you should take into account many different important points - there are no trifles here. To get it done right, read our roundup of the best septic tanks of the year. However, before proceeding with a direct analysis of the characteristics of the models available on the market, let's figure out what this design is and what factors will affect the operation of the equipment. This is where our article will begin.

A large number of similar products can be found on sale; an appropriate classification has been developed for them, based on the principle of operation. The simplest version of this equipment is storage capacity. It is made in the form of a sealed plastic reservoir. Wastewater will enter it and accumulate there. From time to time they will have to be pumped out - for this you will have to use the services of a sewer truck. Product with post-treatment function, which is produced in the soil. This option is also pretty straightforward. The equipment includes one or two reservoirs in which the largest particles settle, and they decompose there without the participation of oxygen. The level of purification is not too high, therefore, the waste water must not be discharged into the environment. For this reason, soil post-treatment is placed, due to which harmful residues of contaminants will remain in a special filter.

You can also find full-fledged biological aerobic treatment plants, when wastewater is purified using special organisms with the participation of oxygen. For this, the structure is equipped with a special compressor that will pump the required amount of air into the septic tank chamber. A similar design is installed taking into account the sanitary standards in force in our country.

When choosing a septic tank, a large number of factors should be taken into account - how many people live in the soil, climatic features, type of soil, the ability to connect to the power grid, the amount of money, and so on. It is taken into account that one person per day should have about 200 liters of water. Be sure to pay attention to the depth of the groundwater, since it is strictly forbidden for drains to enter there. Convenient if the soil is sandy, as sand can act as a natural filter.

The depth of soil freezing is a very important point. If you place a septic tank above this level, then the wastewater in winter can freeze, and this will lead to depressurization of the chamber at best, and at worst - to the failure of the device. However, on the market you can find designs that are designed specifically for such operating conditions.

It is also important to take into account the availability of free space on the site, since a septic tank is a fairly large structure in itself, and besides, it needs to equip a sanitary zone where crops, fruit trees and shrubs cannot be planted. The smallest are the vertical models - you will have to spend more effort to place them in the soil, but you will be able to save a lot on free space.

We took into account all of the above points when choosing the models to be included in our ranking of the best septic tanks this year, but we also took into account numerous user reviews and value for money. Accordingly, the most expensive designs were not included in our review. Now let's analyze the useful qualities of each model.

Budget models

4. Septic tank TANK 2

This building has an ideal price-performance ratio. It accumulates, sludge and treats waste water. The structure is internally divided into three large sections, which are connected in series with each other. The last chamber is divided into two more. The latter contains a biological filter, it is used for anaerobic wastewater treatment. At the exit from it there is another filtration system. Thanks to such design features of the unit, multi-stage cleaning takes place, due to which about 80% of pollutants are removed from the water. This is a fairly high figure. After the waters leave the chamber, they pass into the infiltrator, where the cleaning is completed in full, then they are discharged into the underlying soil layers or into the gutter.

If the septic tank is designed for installation on the territory of a summer cottage, the most suitable structure will be represented by one common building. It includes an external casing, inside which there are partitions with overflows, dividing the entire volume into two or three chambers. In addition, a biological filter with floating loading is provided. There are also two branch pipes - one for the inlet and one for the outlet, there are one or two necks, which are tightly closed with special plastic covers. The maximum number of sections depends on how large the septic tank itself is. Small structures are equipped with two chambers, with their help, up to 600 liters of water can be processed during the day, all other devices are divided into three compartments. The product of the largest volume per day can process up to 1200 liters of water, this volume is quite enough for a family of six.

• Incorrect installation will create an unpleasant odor in the house;
• The accumulating sludge must not be used as fertilizer in summer cottages or garden plots.

3. Termite Profi 1.2

This unit accumulates and absorbs any pollution quite efficiently, so it is quite permissible to use purified water for technical needs, including for irrigating flower beds and even beds. The model is domestically produced, manufactured in strict compliance with all construction and sanitary requirements, so the equipment does not cause the slightest harm to the environment. Waste water passes through both mechanical and biological treatment. The model can have two or three compartments, when passing through which the water is clarified and purified. Initially, the effluent enters the collection chamber, where it settles so that all solid particles settle. Then they go to the bacterial filtration compartment, where special microorganisms living on special brushes remove most of the dirt from there. Not all products are equipped with an additional sedimentation tank, in it the drains are once again settled so that all the remaining contaminants settle to the bottom in the form of silt. All elements are connected to each other using special overflow pipes.

On the site, the structure will not take up too much free space, an empty septic tank weighs about 80 kg, so it can be easily installed manually. It is well suited not only for a country house, but also for a separately located bath. The structure is made of high quality plastic with a wall thickness of 20 mm. They are also equipped with stiffening ribs, so the structure can easily withstand even very serious physical exertion. The product is easy to install and does not require additional maintenance.

Advantages:

• Not dependent on power supply;
• Resists pressure and severe temperature fluctuations well;
• Easy to operate;

2. MICROBE 450

The company that manufactures these products has been on the market for over 25 years. During this time, the manufacturer has managed to establish itself as a reliable manufacturer of sewerage equipment. Today the company is one of the leaders in terms of the production of such devices. This small-sized model is perfect for a summer cottage where people live seasonally. The septic tank includes a plastic container, which is made on the basis of HDPE (low pressure plastic), which withstands well the effects of moisture, low temperatures, pressure drops and other mechanical influences. Inside there is a receiving compartment, where wastewater will flow, from which they pass into the second chamber, having previously passed through a special filter. A special ventilation outlet is also provided through which gases arising from the vital activity of filtering bacteria will escape.

Thanks to this device, it is possible to ensure the degree of water purification up to 85%, in order to increase this indicator, experts recommend installing an infiltrator, but it will have to be purchased separately, however, according to users, instead of it, you can assemble a drainage well with your own hands. Solid waste will accumulate at the bottom of the structure, so it will need to be pumped out periodically - once a year is enough. The manufacturer recommends using this design for a country house, since the model is capable of processing no more than 150-200 liters of wastewater per day. The structure weighs a little; its installation can be done alone. The total volume of the structure is 450 liters with overall dimensions of 0.81x4.13 m, its weight is 35 kg. It is one of the cheapest on the market.

Advantages:

• Small overall dimensions, allowing significant savings in installation costs;
• Ease of maintenance, filters are very easy to change;
• Independent of electricity;
• Decent performance for its overall dimensions;

1. Rostok Mini

The most popular model in its price range. This design effectively cleans domestic wastewater. Like most similar models, the unit is quite simple. It is a decent sized tank, which is internally divided into two chambers. They are connected to each other using an overflow pipe, one of them has a special filter. The drains enter the septic tank by gravity, without using a pump. The inlet pipe is equipped with a damper that prevents the sediment accumulated at the bottom from rising. The first chamber is a settling tank and clarifier. Subsequently, wastewater passes through mesh and sorption filters, which retain large contaminants. The latter is made from a special material - zeolite, and its thickness is 20 cm. After passing through them, no more than 20% of contaminants remain in the water compared to the original state. In this form, they can already go beyond the septic tank and undergo another post-treatment procedure. It can be a soil backfill or a special biological filter.

On sale you can find several types of such products, which differ from each other in volume - from 1000 to 3000 liters. It should be chosen depending on the number of people living in the house. The diameter of the inlet and outlet is 110 mm, which is quite suitable for standard sewer pipes. From the top, the inlet is 80 cm removed, and the outlet - 85 cm. The model is characterized by ease of installation, there is no need to seek help from specialists. The water should be pumped out as needed - usually once or twice a year. The device does not take up too much free space on the site.

Advantages:

• The body of the structure has no seams, which greatly extends its service life;
• There are stiffeners;
• Completely inhibits unpleasant odors;
• The performance is small but stable;
• Maintenance free;

Best fully self-contained designs

3. Uponor Sako

The manufacturer of this septic tank is a well-known Finnish company, which has long been engaged in the production of various equipment for plumbing needs. It produces filtration products and even biological stations. This model does not need to be connected to electricity, there can be from two to four sections inside, the overflow holes are located in the middle. Most of the organic compounds entering this septic tank are decomposed by bacteria, if the particles are insoluble, then they will be removed by pumping. In the second chamber, medium-sized particles settle, the remaining fat floats. The outlet from the septic tank is slightly lower than the inlet, wastewater leaves the device through a tee, leaving the flow distribution well. At this stage, it will already be 55-70% cleared, but the unpleasant odor and turbidity will remain.

After leaving the well, water enters the perforated pipes, which should be located on the drainage from sand and gravel. It is necessary to place special microorganisms in them, which will deal with wastewater treatment. After this pipe, completely purified water either goes into the ground or enters a well equipped with a drainage pump. There are several design options - they differ from each other only in volume.

Advantages:

• High filtration efficiency;
• High-quality body assembly;
• It does not need to be pumped out for a long time.

Disadvantages:

• Rain or drainage runoff can enter the system and the filtering function can be severely impaired.

2. Termite Profi 3.0

This is an original autonomous type sewer system, which is designed for the most efficient wastewater treatment. The device is designed to be installed in areas remote from the central sewerage system. The product absorbs solid particles in a short time, and the water that has passed through the filters can be used for irrigation and other technical needs. These are products of domestic manufacture, during production and during operation, they fully comply with all existing sanitary-epidemiological and construction standards. The principle of operation of the unit is based on mechanical and biological filtration of waste water. The septic tank itself includes two or three tanks. When passing through them, water is not only disinfected and gets rid of contaminants, but also clarified. When using this equipment, it is allowed to use even a washing machine without fear of causing harm to the environment.

The main structural elements here are the storage chamber and the compartment where biological filtration takes place. In some models, there is a secondary tank, where, before leaving, the water will again settle, purifying even more. As a result, pollution is removed from wastewater by 90-95%. The design does not need frequent pumping out - both the manufacturer and direct users recommend doing this once every two to three years. The brushed tank is home to special anaerobic bacteria that need to be renewed from time to time. Maintenance is quite simple, however, coupled with the observance of the operating rules, this allows not only to increase the service life of the product, but also to prevent the formation of a large amount of sludge and activated sludge.

Advantages:

• Acceptable cost;
• Long service life;
• The body is made of reliable materials, there are no seams;
• Easy to install and maintain.

Disadvantages:

• Deep cleaning technology is not provided;
• There is also no filter for cleaning gases formed during the life of bacteria.

1. Triton-ED-3500 Horizontal

The septic tank belongs to the category of two-chamber products. It is used exclusively for the treatment of wastewater, after which they pass into the ground, a purification well, or into an infiltrator. It is made of high-strength polyethylene, the outer casing is equipped with stiffening ribs, it itself is cast, there are no seams. The equipment is allowed to be used in climatic zones where the average temperature during the winter months drops to -30 degrees. The average service life is within 50 years. The product, depending on the need, can be used to create a drainage system in a small country house, where about 3-4 people live. Some people install it as a temporary solution while building a house.

The unit operates on the principle of biological treatment with preliminary water breakdown into light and heavy fractions. In the immediate vicinity of the septic tank, it will be necessary to install an infiltrator or drainage well. At the same time, water is purified in it so well that it can be immediately directed into the ground, especially if it has high absorbent characteristics, for example, sandy soil. According to the manufacturers, the structure needs regular maintenance. In particular, it must be completely pumped out once a year, after which it is filled with clean water. If you do not plan to use the unit in the cold season, then a third of the contents should be removed from there. The kit includes an elongated neck, the diameter of which is 500 mm, so that the septic tank itself can be buried to a considerable depth.

Advantages:

• The device is easy to maintain;
• It is made of polymeric materials that are resistant to decay and stress;
• Long service life without the need for repair work.

Disadvantages:

• Horizontal installation will require a lot of physical effort, and the structure itself will take up a decent amount of space.

The best septic tanks that need power

3. Unilos Astra 8

The device was developed by the domestic company "SBM-group", which is engaged in the manufacture of closed-type systems that independently process the wastewater that has entered them, and remove clean water and sludge that is absolutely safe for the environment. This model is one of the most popular among users. Its main advantage in comparison with foreign analogues is that it practically does not need human intervention during operation. If you install this product correctly, then the owners will have to look there no more than two or three times a year, and then only in order to clean out the accumulated sludge. The body of the model is made of safe and environmentally friendly polypropylene, which perfectly withstands the effects of chemical compounds and is not sensitive to soil pressure. The walls are welded using an original technology, resulting in a one-piece product with a high level of strength. The wall thickness is significant - as much as 2 cm, so the base under the septic tank does not have to be concreted.

There are no mechanical components inside the septic tank, which also has a positive effect on the strength of the equipment. In total, there are four compartments that are connected to each other by airlifts - these are types of overflows, but wastewater is directed there by blowing air. In the first compartment, the waters are clarified and settled, sediment begins to form, bacteria live in the second, and there is no need to replenish their population. It uses modern technology of intermittent aeration, due to which the decomposition of nitrates, if they are contained in the effluent, occurs. The remaining chambers are two more sedimentation tanks, where the waters are completely purified to their original state - the content of pollutants in them does not exceed 2-3% of the original amount.

Advantages:

• Convenient small-sized design;
• High performance;
• Long service life;
• Good cleaning quality.

Disadvantages:

• High price;
• Dependence on energy supply.

2. Eco-Grand 15 (Poplar)

This autonomous sewage system, like most of the others included in our rating of the best septic tanks, does not have metal elements in its design. This approach allows you to prevent the occurrence of oxidative processes, which significantly extends the service life of the equipment. It includes several chambers - a primary sedimentation tank, aeration tank, a secondary sedimentation tank, as well as a sedimentation tank designed to accumulate active sludge. The key scheme for the operation of the equipment is similar to those that were discussed earlier. The design is distinguished by decent overall dimensions, so it has the ability to process significant volumes of wastewater per day. Together with all the additional equipment, it weighs 380 kg, which greatly complicates its installation in a permanent place.

The salvo discharge of wastewater entering the septic tank can reach a volume of 450 liters. The compartment where the controls are located is completely isolated from the drains. It also houses a reliable and rather powerful compressor, due to which the waste water will be pumped from one chamber to another. All control elements do not consume too much electricity - about 2.8 kW are consumed per day.

Advantages:

• Active filtration, all substances are processed very quickly;
• High performance allows the design to be used for large families;
• The working volume is 6 cubic meters.

Disadvantages:

• Expensive.

1. TOPAS 8

In the first place of our review of the best septic tanks of this year, we decided to put this rather productive model, which is capable of passing through itself up to one and a half tons of wastewater during the day. This indicator allows you to use the structure for installation near a large house, where up to 8 people live. The body of the structure is made of reliable plastic, inside it is divided into four chambers, each of which performs specific functions. Wastewater is transported between chambers by means of airlifts, which operate on the basis of a special compressor. The output is fairly clean water - it is quite acceptable to use it for technical needs, including for irrigation of crops or fruit trees. The maximum volume of a salvo discharge for this design is 440 liters. Water is removed by gravity, all electrical parts of this equipment consume up to one and a half kilowatts of electricity per day.

The weight of the product is quite large - as much as 350 kg. The unit can be installed in almost any soil. There is one condition - the groundwater must be as deep as possible, otherwise it will be quite problematic to drain the processed and filtered water. On sale you can find equipment for such a case - they are equipped with a special drainage pump, with the help of which they will go into an irrigation tank or even into an open reservoir, since the drains that have been treated are absolutely harmless to the environment. However, it should be borne in mind that the energy consumption of such a device will be much higher, since the pump is quite powerful.

Advantages:

• Users purchase this design quite often;
• Excellent filtration efficiency;
• High-quality manufacturing of the case;
• Easy to use, does not require complex maintenance.

Disadvantages:

• Not identified.
