Rating of septic tanks for a private home - which septic tank is better in 2020-2021?

The best volatile septic tanks

Treatment stations whose biological filters are populated with aerobic microorganisms are the most technically advanced version of septic tanks. They output water that is 98% purified - it can be used for irrigation, other technical needs, or discharged directly into the ground. Cleaning the tanks of sludge is necessary once every couple of years, and the organic sediment itself is an excellent fertilizer for plants on the site. Since the wastewater does not require additional ground filtration, the structure takes up minimal space.

The main disadvantage of such systems is the need for electricity. The aerobic system always includes an aerator-compressor, which saturates the liquid with oxygen necessary for the life of bacteria. It is this fact that explains the higher cost of volatile stations - both during purchase and installation, and during operation.

Septon

Septic tank "Septon" - new for 2022! Serves 3-15 people. The station provides deep wastewater treatment thanks to bacteria contained in a separate block of the station for up to three months without the entry of organic matter. The model range of septic tanks without pumping is attractive with a variety of options with different capacities, volume of volley discharges, and insertion depth of the supply pipe. The “Smart” module (crushed stone-free drainage system) is optional.

Technological solutions for the best septic tank in 2022

The Septon septic tank is made of homogeneous integrally foamed copolymer (polypropylene + ethylene) and can withstand operating temperatures of +40...-40˚С. The body is represented by a self-supporting cylindrical vessel equipped with a rectangular lid. The neck and lid are painted green. The round shape, one weld seam ensures long-term operation of the septic tank - 25 years. The product has minimal dimensions, occupying 2 m2 of area.

The wastewater is treated biologically using suspended activated sludge. Air is supplied by a membrane tubular polymer aerator. Nitrogen compounds are best removed during general biological treatment. Forced drainage systems are equipped with a built-in storage tank with a drainage pump. The liquid is disinfected with a built-in ultraviolet disinfectant. The GSM system (sold separately) notifies about changes in the operation of the septic tank and simplifies management.

The septic tank operates without noise, odor, and does not require pumping. The degree of wastewater recycling reaches 98%. Conversion of a gravity structure into a forced one is allowed. The absence of fragile parts prevents mechanical breakdowns.

Principle of aerobic biological action

Septon Smart septic tanks for private homes can withstand uneven flow of wastewater, operate effectively at low loads, and support the vital activity of bacteria during large burst discharges, eliminating the washout of microflora. Biological treatment, accompanied by oxidation with oxygen, reduces the BOD and allows clean water to be discharged without filtration fields.

Aerobic-anoxic wastewater processing allows activated sludge to absorb organic and chemical compounds in the presence or absence of dissolved oxygen. The sludge mass, incubated from bacterial strains supplied along with organic waste, forms colonies of bacteria in the form of flakes that are easily separated from clean water. Airlifts, which circulate the liquid with compressed air bubbles, help prevent the destruction of activated sludge flakes.

Contents of delivery

Basic modifications of Septon septic tanks without pumping include a housing, a compressor, a technical passport, and a 110x15° outlet pipe.

Forced drainage systems are additionally equipped with a storage tank, a good drainage pump with a float switch, a reinforced PVC hose, fittings and connectors.

Greenloose Aqua 5

★ Wide selection of modifications Country: Russia Average price: 86,500 rub. Rating (2021): 4.9

Greenlos Aqua 5 septic tanks are designed for constant maintenance of houses inhabited by up to 5 people. Structurally, this model is a sealed housing with 4 internal chambers, in which biological decomposition of wastewater sequentially occurs. Purified water is drained by gravity or forcibly, using the pump equipped with the “Pr” modification. In case of difficult conditions on the site, for example, with a high groundwater level, the manufacturer offers the “Aqua 5 Low body” model. With the same initial characteristics (300 liters salvo discharge, productivity 1 cubic meter/day), it has a body reduced in height and allows the pipe to be installed at a depth of only 600 mm. Unlike most manufacturers, in Grinlos stations the electrical panel is located outside the housing, which protects electrical equipment from moisture, and also preserves the equipment in case of emergency overflow of the station.

However, in the arsenal of the manufacturer Greenlos you can find stations for individual cottages or mini-villages with a number of residents from 2 to 25 people. This range allows users to select the most efficient equipment. In the reviews, users note that they are very satisfied with Greenlos septic tanks. The systems are made of high-quality Czech polypropylene and work properly. However, it is better to entrust the installation to a specialized company, since due to incorrect installation, the system for some do-it-yourself users worked intermittently and had to be reinstalled again.

The best autonomous septic tanks

Autonomous septic tanks that do not require connection to the electrical network are the best option for a summer cottage or a country house in a remote area where there are problems with electricity. Their design does not contain moving mechanical parts, so they are simple, reliable and will perform their functions in any case.

Of course, there are also disadvantages - lower productivity, worse level of wastewater clarification. The best models provide no more than 85% purification, and, therefore, the water requires additional filtration. There are several methods - drainage fields, infiltrators, filtration wells - and all of them mean additional monetary costs and reduce the usable area of ​​the site. However, for houses with periodic residence, such structures may be more preferable, since they do not consume electricity and can be easily mothballed if necessary.

Essence of the device

A septic tank is an element of a cleaning or sewer system in the form of a container, or more precisely, a sealed well for collecting and treating wastewater. It is installed in the absence of a centralized sewerage system and is intended to serve dachas, private houses, utility buildings and other low-rise buildings. This device must comply with applicable regulations. In particular, during design and operation it is necessary to comply with SNiP 2.04.03-85 and SP 32.13330-2012.

Snip for placing a septic tank on a residential plot

To ensure functions, the following requirements are put forward to septic tanks:

• sufficient mechanical strength to withstand liquid inside and soil exposure outside;
• tightness, preventing soil contamination by runoff;
• water resistance and resistance to various components of soil and sewage, excluding rotting, corrosion and other chemical reactions;
• ease of installation;
• durability and environmental friendliness.

The septic tank must be sealed so that water does not seep into the ground and pollute it

The tightness of the container must prevent the release of released gases into the air.

Wastewater treatment plant performance

To ensure trouble-free operation of the septic tank and prevent overcrowding of the tanks, it is important to select the correct performance of the model. This parameter, in turn, is related to the volume of chambers and their number

It was already indicated above that the average daily volume of fluid consumption is about 200 liters per person. A septic tank, according to accepted norms and rules, must accommodate the amount of wastewater for three days, so this figure should be tripled and multiplied by the number of residents. The result obtained will be the required productivity of the recycler, but experts do not recommend choosing “the minimum”; you should make a small reserve - 10-15% of the calculated volume, which is a kind of insurance and a way to reduce the risk of overfilling the tanks.

Having decided on the volume of the product, you can decide on the number of cameras.

• Single-chamber models are suitable for a minimum amount of waste (the average daily volume is less than a cubic meter).
• If the daily volume of wastewater is no more than ten cubic meters, a two-chamber septic tank would be the best option.
• Three-chamber models will ensure trouble-free waste disposal, even if a family of 4 people permanently lives in the house; they are designed to process wastewater in a volume of more than 10 cubic meters per day.

Ecopan

The Ecopan T series septic tank was specially designed for use on problematic heaving soils and with a high clay content. The destructive effect of soil on containers is compensated by a two-layer design with many internal partitions between the surface polymer layers. For light soils, Ecopan L series is used, in which resistance to mechanical damage is ensured by a wall thickness of up to 8 mm.

Six sections of the septic tank carry out a step-by-step process of cleaning the sewer. In the first compartment, light and heavy suspensions are deposited, which are pumped out as they accumulate through the hatch provided by the manufacturers. Next, the aerobic process takes place inside the next compartment. Brush loading ensures the high-quality development of bacteria, which in turn decompose organic compounds. Additionally, in the next chamber (aeration tank), oxygen is supplied by a compressor to deepen the process of decomposition and oxidation.

Calming of the mixture and sedimentation of suspensions occurs in the next compartment, from where the sediment is pumped into the first chamber for further removal. To purify wastewater to the required values, the penultimate compartment is used, where colonies of organisms on a brush load complete the process of decomposition of biomaterials, and limestone ensures a normal pH of the environment. From the last chamber, purified water is removed from the system by means of a pump or by gravity.

Unilos

The combination of two types of treatment (biological and mechanical) makes it possible to remove contaminants from sewage and maintain the environmental safety of a suburban area. Unilos continues a series of septic tanks that implement the principle of water passing through several compartments. Firstly, it is the removal of mechanical impurities that settle to the bottom and are removed as they accumulate. Secondly, biological treatment using anaerobic technology. In the chamber, organic contaminants from the liquid phase pass into a solid insoluble form, which is convenient for removing them from water through filters. At the last stage, the final sedimentation of suspensions and the removal of 95-98% pure water occurs.

The process of equipment operation involves interruptions in the power supply. The estimated service life is more than 50 years. The strength of the case is ensured by the manufacture of walls made of polypropylene with a thickness of 20 mm. You can read more in our review.

Rating of domestic offers

Despite the fact that the production of treatment facilities for local sewage systems in Russia began recently, some of the companies have already established themselves as reliable manufacturers. Their quality is in no way inferior to European standards. In addition, domestic models are cheaper than imported ones. According to consumer surveys, several companies are recognized as the best manufacturers of treatment facilities on the Russian market.

Eurobion

Thanks to the introduction of membrane technology into septic tanks of its own production, the Yubas production association has earned a worthy place in the ranking of domestic manufacturers. Their systems are considered reliable and work properly even after long periods of inactivity.

Eurobion cross-section, work diagram

Poplar

These septic tanks are produced by the Eco-Grand brand. Their models are famous for their high level of sewage treatment (99%). The manufacturer uses a non-standard scheme in the production of its products. Namely, open access to the primary sections simplifies maintenance of the treatment system. Garbage can be removed from them on your own, without the involvement of sludge extraction equipment.

Types of septic tanks Poplar

Aster

Specializes in the production of septic tanks. The products are offered under the Unilos brand. Guarantees a high degree of wastewater purification (about 75%). It produces several types of treatment facilities depending on the degree of complexity. The stations are complemented by special compressors responsible for the quality of cleaning. The purification process is carried out in several stages.

Septic tank Astra

Tank

The Russian one is responsible for the quality of this line of septic tanks. This company produces septic tanks with varying degrees of productivity:

1. Compact in size with the ability to process up to 600 liters per day.
2. High-performance models capable of cleaning about 1200 liters per day. The parameters of their products are similar to classic recycling stations operating using multi-stage technology.

Range of treatment facilities Tank

Triton

Products from the same company. They have several configurations and cleaning methods. They can process from 450 liters per day (“Mini”) to 750 liters per day.

Topas

All models under this brand consume little electricity. The structures consist of 4 wells. All stages of purification, including anaerobic, are carried out in them. The degree of wastewater purification is 98%.

Topas - top view

Tver

These septic tanks are manufactured by the Engineering Equipment trading house. The peculiarity of these structures is that sewage treatment can be carried out both chemically and biologically. Each station is equipped with a 4-level water clarification technology. It can, depending on the model, process 750-1500 cubic meters of wastewater in 1 day.

Tver in section

Rostock and Leader companies have also proven themselves well in the domestic market.

Which of the septic tanks listed above is the best is up to each individual to decide. There are no clear parameters or standards here. The main thing is that it satisfies all user requests, is easy to maintain/use, is inexpensive, and lasts a long time.

Criterias of choice

It should be noted that the quality of cleaning demonstrated by systems with a septic tank and aeration equipment, installed taking into account all requirements, complies with current standards. However, it is worth assessing the objective parameters, since choosing the right septic tank for a country house is possible only by taking into account all the characteristics.

• Waste disposal. In addition to wastewater treatment, it is also necessary to ensure their disposal. Even if you have almost completely removed all the contaminants, you still need to drain cubic meters of water somewhere. In the case of autonomous septic tanks, the disposal process, together with post-treatment, takes place in natural soil. For this purpose, filtration fields or other drainage systems are installed.
• When using aeration treatment equipment, there is no need to carry out additional wastewater treatment, but volumes of purified water still have to be drained. In the absence of natural reservoirs, drainage systems (trenches, wells, filtration fields) are used for this purpose. If wastewater after treatment is discharged into natural pools, then the treatment equipment must be equipped with a biofilter.
• The first thing you should think about before purchasing a purification system is how and where the wastewater will be discharged. Several important parameters are taken into account here: the volume of purified liquid, the level of soil moisture capacity, the location of groundwater, and the total area of ​​the land plot. Also, do not forget about the nearest storm drain or any place where water constantly accumulates.
• Have you wondered how much wastewater you produce every day? On average, each family member spends at least 150 liters. In order for your septic tank to function properly, its volume must be nearly three times the amount of daily wastewater flow. In an ordinary family (parents and one child), a septic tank should be installed with a volume of about 1200-1300 liters. At the same time, we exclude the possibility of unforeseen situations or the appearance of relatives who decide to stay.
• High quality installation. You may have heard that some wastewater treatment systems are used only during the summer season, while others are used all year round. However, the main parameter here is not the weather, but the correct installation of equipment. Both aeration and anaerobic plants work great at any time.
• To extend the life of biological stations and ensure their uninterrupted operation, it is important to completely eliminate the possibility of drainage freezing. The liquid should go quietly into the ground. Also remember that the storage and filtration tank itself cannot be frozen. This threatens not only the transformation of the internal contents into ice, but also the destruction of bacteria responsible for cleaning wastewater. Place the drainage system, septic tank and other equipment well below the soil freezing level. In the spring, when the summer season is just beginning, we recommend purchasing a special bioaccelerator for the cleaning station. The substance will help to quickly activate biological processes inside the installation.
• Energy dependence or autonomy. Septic tanks are divided into two broad categories. Some do not require a power source, while others require an electrical connection. They are also called aeration tanks. The kit includes a compressor to increase the pressure and a pump that requires power. If power outages are common in your area, this could cost the lives of all the bacteria within the system. As for non-volatile septic tanks, they are not afraid of problems with power supply, since there is no such equipment.
• The need for maintenance. The work does not end when the VOC is installed. Next, it is necessary to periodically carry out maintenance of the system. Regardless of the type of equipment, sediment accumulates inside during operation. If we talk about the frequency of cleaning, aeration-type stations require more care and attention: removing sludge, checking the functioning of parts. The septic tank is completely cleaned of insoluble substances. This can be done every six months. If you use a special drug - a bioaccelerator, servicing will be needed even less often. Active microbiological processes begin to occur inside the septic tank.
• Compliance with sanitary standards. Russian legislation establishes standards for wastewater treatment and disposal. They establish rules on the distance between treatment plants and residential buildings. So the buyer should pay attention not only to the characteristics of the equipment, but also to the legality of its placement. The following parameters have been determined: the distance from a residential property to the aeration system cannot be less than 50 m, to the septic tank - only 5 m.

Types of septic tanks

• Storage type septic tanks. A primitive local structure that is easy to install. This septic tank is a reservoir in which various wastewater accumulates. The system is used in the country. Can be constructed from various materials. The capacity of the structure may vary depending on the number of people. On average, the capacity of the container reaches 10 m3 of waste. You can install storage sewer not only in the ground. Some users prefer to leave it on the ground. In simple terms, a septic tank is an improved septic tank. As soon as the container is full, it is necessary to call a team of sewers to clean the drains. The main disadvantage of installing a storage septic tank is the need for periodic pumping. Unfortunately, this cannot be done on your own. You have to pay for the services of a sewer truck. Most often, the local device is installed by those owners of dachas and country houses who live on the territory temporarily. If you want to resort to pumping out wastewater as little as possible and not spend money on it, waste must be reduced as much as possible. This option can be considered if you need to choose a septic tank for a summer residence with non-permanent residence. The cheapest solution is a plastic container, which is perfect for seasonal and short-term use.
• Septic tanks of purification type. Unlike storage systems, cleaning systems are more complex. They are worth purchasing if it is important to choose a septic tank for a private home with permanent residence. The structure allows not only to accumulate, but also to clean waste. Prices vary depending on several criteria:
• cleaning methods;
• system volumes;
• wastewater filtration results;
• other functions.

Based on the power of the system, the quality of waste treatment can reach from 50 to 98%. For example, a sump allows you to filter the water that enters the purification device up to 75%, which is sometimes a sufficient indicator. To discharge purified liquid into groundwater, its disinfection level must be at least 95%. More complex equipment – ​​a biological treatment station – can handle this. Do not think that its installation and maintenance are difficult. Modern devices are characterized by simplicity and compactness. A conventional biotreatment station is a three-chamber tank in which dirty wastewater goes through all stages of mechanical and biological purification. As a result, you get a liquid in which hazardous substances are 98% removed. As a result, the water can be completely safely used for discharging into the soil and watering garden vegetation.

Types by degree of autonomy

• Energy-dependent – ​​convenient, efficient treatment facilities. Virtually no additional maintenance is required. The wastewater entering the septic tank undergoes a full filtration cycle and can be discharged into the ground or ditch. If there is no power source, the quality of cleaning the system drops significantly, turning the structure into a regular septic tank. Therefore, the main disadvantage of these devices is not only their cost, but also their dependence on the energy source.
• Non-volatile, or autonomous, storage tanks in which human waste is collected. They are serviced by sewer trucks, since it is not possible to pump out the wastewater yourself. Since in such septic tanks there is a minimum of filtration, it is necessary to carry out additional water purification. This requires a vacant plot of land. The advantages of non-volatile septic tanks: low cost, no power supply.

Leader

Leader septic tanks use electricity to remove sediment from sedimentation tanks (air lift) and to run the aerator, which oxidizes organic matter. However, it can be characterized as non-volatile, since the estimated period of operation without electricity and while maintaining the quality of waste water is at least two weeks. Four-stage cleaning does not require the use of special biological additives and is resistant to temporary overloads of sewage pollution.

Wastewater treatment is carried out in such a way that it can be discharged into a place convenient for you: a reservoir, ditches or a drainage well. There are no violations of the environment or standards for the discharge of pollutants, complete consistency with the surrounding nature. The advantages of a septic tank include the absence of the need to make a concrete base and preserve the equipment during long-term downtime.

Local wastewater treatment is carried out according to the principle of passing through all stages of the tank without pumping out the accumulated mass. The first chamber is intended for the mechanical stage of purification - sedimentation of suspended particles and primary clarification of water. The manufacturer indicates that the effectiveness of the first chamber reaches the deposition of 2/3 of mineral contaminants. The second stage is a bioreactor, where anaerobic bacteria initiate fermentation, a process that converts difficult-to-oxidize substances into easier ones for the oxidation process. Bacteria develop on a special polymer line that imitates algae. In the third block of the septic tank, wastewater is purified with oxygen through aeration. Bacteria multiply on porous material and in activated sludge. And the result in this victorious battle with sewage is the fourth stage of the septic tank. It is here that deep biopurification and neutralization of phosphates is carried out in the alkaline environment of dissolved limestone.

The operation of the installation is subject to a rather complex algorithm, which, nevertheless, is implemented with maximum technical simplicity. Repeating the same processes many times allows you to achieve the maximum degree of water purification from all types of organic contaminants.

The monolithic body of the septic tank does not allow wastewater to penetrate directly into the ground, and its operation allows interruptions in the use of equipment for up to 3 months. The use of treatment equipment control processors was also an innovative solution. It is enough for the owners of a septic tank to carry out timely cleaning of the sedimentation chamber of mechanical suspensions, and the rest of the work is done by automation.

Septic tank TANK 2

This building has an ideal price-quality ratio. It accumulates, settles and treats wastewater. The structure is internally divided into three large sections, which are connected in series to each other. The last chamber is divided into two more. The latter contains a biological filter; it is used for anaerobic processing of wastewater. At the outlet there is another filtration system. Thanks to these design features of the unit, multi-stage cleaning occurs, due to which approximately 80% of pollutants are removed from the water. This is a fairly high figure. After the water leaves the chamber, it passes into the infiltrator, where the purification is fully completed, then it is discharged into the underlying soil layers or into the drainage ditch.

If the septic tank is designed for installation on the territory of a summer cottage, the most suitable design will be a design represented by one common building. It includes an outer casing, inside of which there are partitions with overflows, dividing the entire volume into two or three chambers. In addition to them, a biological filter with floating loading is provided. There are also two pipes - one for the inlet and one for the outlet; there are one or two necks that are tightly closed with special plastic caps. 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 largest volume product can process up to 1200 liters of water per day, this volume is quite enough for a family of six people.

Septic tank TANK 2

Termite Pro 1.2

This unit accumulates and absorbs any contaminants quite efficiently, so it is quite acceptable to use purified water for technical needs, including for watering flower beds and even beds. The model is domestically produced and is manufactured in strict compliance with all construction and sanitary requirements, so the equipment does not cause the slightest harm to the environment. Wastewater passes through both mechanical and biological treatment. The model may have two or three compartments, through which the water is clarified and purified. Initially, the wastewater enters a storage chamber, where it settles so that all solid particles settle. Then they move to the bacterial filtration compartment, where special microorganisms living on special brushes remove most of the contaminants from there. Not all products are equipped with an additional settling tank; the wastewater is once again settled in it so that all remaining contaminants settle to the bottom in the form of sludge. 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 installed manually. It is well suited not only for a country house, but also for a separate bathhouse. The structure is made of high-quality plastic, and the wall thickness is 20 mm. They are also equipped with stiffening ribs, so the structure can easily withstand even very severe physical loads. The product is easy to install and does not require additional maintenance.

Advantages:

• Not dependent on power supply;
• Resists pressure and serious temperature changes well;
• Easy to use;
• Durable model;
• The output is almost perfectly pure water.

Flaws:

• Manufacturers do not recommend installing the structure in areas close to the groundwater surface.

MICROB 450

The company producing these products has been on the market for more than 25 years. During this time, the manufacturer managed to establish itself as a reliable manufacturer of sewerage equipment. Today the company is one of the leaders in terms of 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 can withstand moisture, low temperatures, pressure changes and other mechanical influences. Inside there is a receiving compartment where wastewater will flow, from which it passes into the second chamber, after first passing through a special filter. There is also a special ventilation outlet through which gases resulting from the activity of filter bacteria will escape.

Thanks to this device, it is possible to ensure a degree of water purification of up to 85%; to increase this indicator, experts recommend installing an infiltrator, but it will have to be purchased separately; however, according to users, you can instead 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 sufficient. 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 and can be installed 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 on installation;
• Easy to maintain, filters are very easy to change;
• Independent of electricity;
• Decent performance for its overall dimensions;
• High level of strength and durability of the product.

Flaws:

• Do not use too aggressive chemicals;
• Due to its light weight, it can float during spring floods - you have to additionally secure it in the ground.

Rostok Mini

The most popular model in its price category. This design efficiently purifies domestic wastewater. Like most similar models, the unit is designed quite simply. It is a decent-sized tank, which is divided from the inside into two chambers. They are connected to each other using an overflow pipe; one of them has a special filter. The wastewater flows into the septic tank by gravity, without the use of a pump. The inlet pipe is equipped with a damper that prevents sediment accumulated at the bottom from rising. The first chamber is a settling tank and clarifier. Subsequently, the 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 additional treatment procedure. It can be a soil backfill or a special biological filter.
