Which septic tank is better in a private house? Septic tank for a private house - what the sewerage system looks like

How to choose a septic tank for a private house

In the absence of the possibility of connecting to a centralized sewage line, the owners of country houses have to take care of arranging local wastewater treatment systems. Septic tanks can help with this without affecting the environment. There are many types of such devices. Therefore, those who decide to install local sewerage on your site, the question arises of which device is better to choose.

Types of septic tanks

The main classification of systems for the disposal of wastewater from a private house is based on the principle of operation.

Storage tanks are the easiest option. They are sealed containers. In these containers, sewage enters and accumulates there, which must be pumped out, periodically calling a sewage truck.

Note! It is necessary to choose a place on the site for the placement of septic tanks that carry out aerobic or anaerobic wastewater treatment, taking into account sanitary rules.

There are ready-made versions of various companies on the market, but with certain skills, you can make them yourself, for example, from concrete rings. The material, along with the design and other important parameters, is one of the factors that are taken into account when choosing a septic tank.

What should be considered when choosing a waste disposal device?

Before buying a septic tank, you need to answer a few questions.

1. How many people will live in the house, what sanitary equipment will be installed? These factors determine the performance and volume of the septic tank.
2. What are the features of the soil?
3. What is the planned budget?
4. Is it possible to connect to electricity?
5. Can you make a septic tank yourself or do you prefer to buy a ready-made device?

How many people will live in the house

This setting affects performance. To determine it, you need to multiply the number of inhabitants by 200 liters, because that is how many drains per day, according to the standard, form one person.

Wastewater stays in the treatment plant for about three days. Therefore, productivity must be tripled in order to obtain the required volume of the station. It is also necessary to take into account the possibility of the arrival of guests, as well as decide whether the house will have such sanitary equipment as a bathtub, dishwasher and washing machine.

The number of residents affects the type of building chosen and the design features.

If it is planned to live in a house with a small family only in the summer, then the drive will be enough. To service a year-round home, you should choose a cleaning station.

The number of users determines the number of soil-filtered septic tanks. So, for a house in which 3 people will live, a single-chamber septic tank is enough. If more than 1 but less than 10 m3 of wastewater is generated per day, it is recommended to install a device from two tanks.

Aeration stations do best with large volumes.

Features of natural conditions

The depth of penetration of the primer and the type of soil determine whether it is possible to equip a soil filtration stage that will work effectively only on sandy loams and sands and low GWL.

Occurrence scheme ground water

It is possible to install post-treatment on loam and clay, but these works will require a lot of time, money and physical costs.

The design features of septic tanks depend on the depth of soil freezing. A large neck allows you to deepen the device. Among the finished products there are options for installation in the ground with a deep point of zero temperatures.

Septic tank with sealed chambers

If you need to install a drive on heavily freezing soils, then you should give preference to vertical tanks. But in areas with a nearby primer, it is better to mount horizontal storage tanks.

Scheme of installation of a vertical septic tank

With a significant amount of wastewater and unsuitable natural conditions, it is better to choose a biological treatment plant. True, their cost will be higher.

Local sewerage costs

The amount of money that the owner of the house can allocate for the arrangement of the sewer system remains one of the main parameters for choosing a septic tank.

The most expensive are prefabricated plastic treatment plants, especially those that aerate wastewater. There are models produced in Russia and proven by users: Topas, Astra. You can also purchase European septic tanks, for example, Uponor. On average, biotreatment stations cost 80-100 thousand rubles.

If a natural conditions allow, then you can opt for ready-made septic tanks with soil purification. Among such devices, the most popular are the Tank treatment plants, which cost about 35-50 thousand rubles, excluding the additional stage. An oxygen-free septic tank can also be equipped from improvised materials, for example, from eurocubes, especially if you purchase used containers that cost about 4-5 thousand rubles.

The design of a septic tank from eurocubes

The cheapest option is storage tanks.

The price of the finished product is also affected by what it is made of.

1. Concrete rings are a traditional and inexpensive material for septic tanks. But for their installation it is necessary to hire lifting equipment, which is not cheap.
2. Ready-made plastic septic tanks are also often used, they are more expensive, but they can be released into the pit by 1-2 people. In addition, you can make a tank from a thick-walled pipe of large diameter or use eurocubes.

Note! Plastic products are exposed to the ascent under groundwater pressure, so they must be installed on a concrete base, to which the container is attached.

To save yourself from the need to inhale odors from cesspools, it makes sense to buy a septic tank for a private house, having previously studied its features and giving preference to a specific variety. The device will save the residents of the house from any trouble. With the constant residence of a large number of people on the territory of a private house, the drain pit simply cannot cope with the task and it will need an assistant, who can become a septic tank.

What is a septic tank

Private houses or country cottages differ from ordinary apartments the fact that there is no central sewage system and the use of a special device will be required to remove household water. A septic tank is a sealed container in which liquid waste accumulates. The function of biological treatment is available to some models, but they cannot be classified as full-fledged treatment facilities.

What is it needed for

Owners of country houses, when arranging sewage, must ensure that wastewater is treated, taking into account sanitary standards and soil characteristics. A reliable option would be a septic tank, also called a septic tank, whose function is to accumulate and purify waste leaving the premises. It passes impurities through itself, not allowing it to penetrate the soil. Before you make a septic tank in a private house, you should understand its structure and operation.

Device

When building a cottage, it is necessary to pay special attention to the arrangement of an autonomous sewage system, since there is no central one according to the project. The device of a septic tank in a private house allows you to solve problems with the removal of household waste and their cleaning. The work is carried out in three stages:

• Sewerage from a private house is collected in sealed plastic containers of a local treatment plant.
• Inside the septic tank, particles are separated into heavy and light particles. The former settle at the bottom of the well, while the latter enter the next compartment.
• Aerobic purification is not always possible, so anaerobic purification often occurs. Impurities are filtered, and the formed methane is removed by means of an exhaust pipe.

Types of septic tanks for a private house

Local treatment facilities divided into two large groups - old and new. The first group is represented by brick septic tanks and reinforced concrete structures. These types for private houses are used less frequently due to time, power and material costs. However, concrete structures are considered more durable. The new ones include ready-made plastic septic tanks for the home, which have several more subspecies. Of the undoubted advantages, one can single out the cheapness, practicality of plastic, and the lightness of the product.

Cumulative

Manufacturers of septic tanks installed in private homes understand that it is impossible to do without a sewer system, so they offer a wide choice. The use of special tanks often becomes a solution to the problem. A storage septic tank is a container where household water flows through pipes, pumped out as it fills. Calculations of the volume of liquid must be made independently and, based on this, order a storage tank of the desired size. This option has a number of features:

• Installation of drainage wells is not required, which has a positive effect on the cost of the system.
• The tank itself for a private house will be expensive, despite the simplicity of the device.
• The owner of the house can independently decide where the septic tank will be installed. However, everything needs to be thought out so that the entrance of the sewage truck is unhindered.
• It will be expensive to pump out waste, therefore, if domestic water accumulates quickly, then a single-chamber septic tank is not your option!

It is impossible to ensure a comfortable life for permanent residence in a private house without sewerage. Bioseptic with the help of special bacteria solves the problem of wastewater treatment, giving a kind of guarantee of soil safety. The process looks like this:

1. Sewage enters the first chamber of a popular septic tank, undergoing primary treatment there. There is a separation of large particles and fats that settle on the bottom.
2. Waste is sent to the second tank of the three-chamber septic tank, where cleaning continues more actively.
3. The sludge enters the first chamber, and the treated effluents enter the third, where the final and main stage takes place.
4. Completely purified water through the secondary sump enters the well.

With post-treatment

Waste that has passed through a septic tank cannot be considered completely clean water that can be dumped into a reservoir or soil. Sometimes soil cleaning is indispensable. The design of a treatment plant for a private house depends on various parameters: the characteristics of wastewater and soil. Soil filtration is more costly, as you will need to install:

• absorbent trench,
• sand and gravel filter,
• filter well,
• filter fields.

Septic tanks for the home

It is not easy to make a choice from the assortment available for sale. Initially, the eye falls on those devices that are cheap:

• Name: KNS Unipump Sanivort.
• Price: 11328 rubles.
• Characteristics: the device pumps out wastewater, accumulating them in the reservoir.
• Pros: low price.
• Cons: small capacity.

More serious septic tanks installed in private homes are many times more expensive. However, they are often worth it:

• Title: EcoProm Rostock.
• Price: 55900 rubles.
• Characteristics: design containing a biological filter for wastewater treatment.
• Pros: high degree cleaning.
• Cons: large dimensions.

There are entire autonomous stations for deep biological treatment. In a private house, they will be appropriate:

• Name: Unilos Astra 3.
• Price: 66300 rubles.
• Characteristics: container for collecting and filtering sewage, occurring in several stages.
• Pros: Easy to use, does the job well.
• Cons: none.

The cost of installing a septic tank

Retail and online stores are full of sales, promotions and discounts. Before you install a septic tank to filter waste in a private house, you need to purchase it. It is not recommended to order delivery by mail, it is better to use the services of a transport company. You can buy a septic tank for a house, depending on its variety, at a price of 12,000 to 70,000 rubles. However, buying is half the battle. Installation costs may vary.

Septic tank for a private house: how to choose, reviews
A septic tank for a private house is a solution to problems with sewage and getting rid of the unpleasant odors of liquid waste. Learn about the types of devices and why you can't do without it.

A practical and successful version of the sewerage device on your site - a septic tank - is a type of treatment plant that allows you to clean and dispose of wastewater. How to choose the right septic tank for a private house? The owner of a country dwelling usually, when choosing a design, pays attention to its price and performance. The last factor will determine how effectively the product will cope with its intended purpose. The variety of these treatment facilities on the modern market will make even the most sophisticated consumer in these matters confused. Local installation, included in the sewer system and used to collect, settle and purify polluted water from the home. For normal country house they are of the following types:

Filling type - the structure can be made independently using concrete rings, Eurocube, etc.,

Settling tanks with post-treatment through the ground,

Installations for deep cleaning.

When choosing the best option for a septic tank, you should also pay attention to the material of its manufacture, the type of soil where it will be installed, the purpose of the dwelling (for stationary or seasonal residence).

Types of septic tanks for a country house

Previously, when the production of plastic septic tanks was not so massive, reinforced concrete structures were more popular, which were assembled in stages. Cleaning systems made of metal were also used. Today, wastewater treatment most often occurs with the help of ready-made plastic installations. These products are reliable and durable. A high level of sealing ensures the environmental safety of the installations. Depending on the performance characteristics, they are classified according to different criteria.

By type of filtration

The classic storage option is an analogue of a conventional settling pit into which wastewater flows.

Accumulative model of a septic tank U1250 with a volume of 1250 l (Cost about 25,000 rubles)

In such tanks, water is stored until it is pumped out by a sewage machine. Storage plants require regular cleaning. Although the cost of such containers is small, but the frequent call of machines for cleaning is an expensive “pleasure”. Therefore, such a choice can hardly be called economical.

With soil cleaning - this option defends and cleans drains through a special drainage field.

Model Rostock 1000 with a volume of 1000 liters (Cost about 25,000 rubles)

Water is thrown out, and sediment remains in the tank itself, which must be removed 2-3 times a year using special equipment. As a result of treatment in such a septic tank, the water becomes 60-85% cleaner. Energy independence and ease of operation are the advantages of such a structure. But it cannot be installed in areas with high aquifers due to poor cleaning through soil filters.

Septic tank with deep biological treatment - in this case, you can achieve a high level of wastewater treatment (98-99%) and even reuse the liquid for household needs or for watering the garden.

Model Dochista Profi H5 with a volume of 1000 liters (Cost about 65,000 rubles)

In this option, all types of wastewater treatment are used: chemical, biological, mechanical. Such tanks can be installed in any type of soil, they do not rot and can serve for several decades. The disadvantages of biological septic tanks include their energy dependence. Therefore, in areas where power is often turned off, it will be difficult to achieve the normal functioning of the installation.

By material

From reinforced concrete - this option can be chosen for houses where they live off-season, that is, all year round. They serve for a long time, but need good waterproofing and are quite difficult to install.

Plastic containers can be installed in areas where the groundwater level is high. Plastic septic tanks for a private house are not subject to corrosion and are not afraid of the influence of aggressive environments.

Metal tanks are made of stainless steel. However, compared to plastic and concrete counterparts, they are not so durable and practical. In addition, such septic tanks are quite expensive.

A horizontal septic tank is most often chosen for areas where water from the ground rises high in the autumn-spring period.

The horizontal container has the form of a cylinder and is made of plastic or stainless steel. Suitable for setting up a country house with large quantity waste water (10 or more cubic meters).

A vertical septic tank burrows deeper than a horizontal tank.

Such products are suitable for installation in a sewerage system with a small amount of wastewater (up to 2 cubic meters). However, such a tank is more airtight than the horizontal version.

Sometimes a combined version of horizontal and vertical septic tanks is used, where each tank is responsible for certain wastewater from the bathroom, kitchen or toilet.

By location

Underground - a more common version of the design, which is buried to a certain depth. At the same time, the landscape of the site is not affected.

The ground version of the structure is used if the geology of the site does not allow the installation of an underground version due to the high level of groundwater. In this case, the septic tank will spoil the landscape of the site, so it should be mounted away from the viewing angle.

What to consider when choosing a septic tank

In order to choose the right and buy a septic tank for a country house or a dwelling located in the private sector, you should take into account the purpose of the premises itself.

If the house will be used only during a certain season, then a simpler version of a sewage treatment plant will do.

Water consumption per day is also taken into account. Based on this indicator, the required performance of the septic tank is determined. Water consumption depends on the number of people living in the house.

Soil characteristics are also taken into account. The possibility of installation on site should be determined. After all, the territory itself must meet sanitary standards: the distance from the septic tank to the residential building is 5 meters, from the septic tank to the well or well - 30 meters. If the site is small, then it is unlikely to meet all the necessary requirements. In this case, preference should be given to a more expensive option - sewage with biological treatment.

The location of the septic tank on the site

At the site where the storage tank is installed, entrances for a sewage truck should be provided.

Best option: resume

To correctly choose a septic tank for a country house, you should take into account all the recommendations and make the necessary calculations. The current budget also matters, because some types are more expensive, but are not always an appropriate construction option in a particular situation. An optimally selected design model will be a guarantee of environmental safety and cleanliness of the soil, and timely maintenance of the tank and pumping out wastewater (if provided for by the instructions) will extend its service life for a long time. The best option for a sewer tank will allow you to build a high-quality sewer system on the site and significantly improve living conditions in a private house.

Which septic tank to choose for a private house?
How to choose the right septic tank for a private house? The owner of a country dwelling usually, when choosing a design, pays attention to its price and performance.

An overview article on how to correctly choose the right septic tank for a private house.

First: proceed from their number of people who will use the septic tank

For each person, at least two hundred liters per day will be required, that is, if there are five people in the family, then the septic tank for a three-day stay in it should have a volume of at least three cubic meters.

It is also worth considering the volume of salvo discharge of water, it comes from several sources at once (this is a bath, shower, sinks, toilets). If you calculate the water consumption incorrectly and exceed the flow volume, this will affect the quality of water treatment.

Second: Frequency of use

Aeration units such as "Unilos", "Topas", "Astra", "Bioxi" are perfect for year-round operation. If the flow of effluents ceases, then the activity of microorganisms is inhibited.

In order to use the septic tank occasionally, it is necessary to bring additional food into the sewer, most often it is semolina, pet food, kefir. After receiving top dressing, the activated sludge biocenosis is restored, and the septic tank is operating normally.

Third: a way to divert the drain

Usually there are three ways to remove wastewater:

• Into the ground - this method is suitable if the soil consists of sand or is sandy loam. Drains go into a filter well with a crushed stone or gravel cushion at the bottom,
• In the "stormwater" - this method is suitable if the degree of filtration is approaching 98%, since you can get a fine for water pollution. The method is appropriate when your site has soil that does not absorb water well, for example, clay, or if you have an excessively high level of groundwater,
• In an intermediate well - the method is suitable for several houses sharing one station. This well is built of concrete, and water does not leave it, it is dumped onto the terrain using a drainage pump.

The discharge of water into a common ditch is prohibited due to the fact that aeration stations cannot completely destroy helminth eggs. Therefore, there is a risk of infecting other residents with intestinal diseases.

Fourth: The depth to which the soil freezes in winter

You can find out how much the soil freezes in your area by focusing on SNiP 23-01-99. For example, in the Moscow Region, the soil freezes by 1.4 m.

That is, if you plan to use a septic tank in the winter, you need to lay it below the freezing point, otherwise you risk an accident.

Fifth: Station cost

The Topas and Astra brands are similar and have approximately the same price tag. The differences between them relate to design features (one compressor is installed in Topas, and two in Astra), the number of modifications in the depth of the underwater pipe, and the hull material. Bioksi stations provide for the possibility of processing a larger volume of runoff with a similar number of users. Therefore, the price tag for the products of this brand is slightly higher. For a private house, the option is optimal.

Also on the market there is a firm "Tver", which offers a combined type of treatment systems. These septic tanks have a chamber for anaerobic processes. In fact, it is a complex of a septic tank and an aeration unit. These systems are ideal for occasional use, but they are more expensive.

How do treatment plants work?

The compressor supplies small air bubbles to the aeration tanks, which cause oxidation. Then the wastewater is pumped into a biofilter or aeration tank, and the remaining organic matter is destroyed in it. If you have an aeration tank, then in it a mixture of water and sludge is sent to a secondary sump, where the effluent is separated into water and sludge, and bacteria are involved in the processing of organic matter. Aerobic bacteria are used here. The biofilter, in turn, uses anaerobic bacteria, which can exist in an oxygen-free environment, therefore, the supply of oxygen to the chamber is not necessary. Purified water is either removed by gravity or with the help of special mechanisms, sludge remains.

Overview of units on the market

Consider the most popular settings.

Topas Station

Domestic production, one of the first in Russia.

His work is based on the combination of biological treatment with fine bubble aeration (artificial air supply) for more efficient and faster oxidation of domestic wastewater constituents. Biological purification is the biochemical destruction of organic substances by microorganisms (bacteria). In this type of installation, aerobic bacteria are used, due to them, the processes of biochemical destruction of organic substances occur.

Septic tanks of this company have a large number of modifications:

• Based on the number of people living, modifications have been developed for four, five, six, eight, nine, ten or more people who live in a private house, in a country house, in a cottage,
• Modifications that take into account the depth of the pipe that leads the drains out of the house,
• Septic tank models can have one or two compressors,
• Septic tank models may have a drainage pump,
• In addition to modifications for the house, the company has developed septic tanks for a holiday village, a camp site, a country community with a capacity of fifty, seventy, one hundred, one hundred and fifty inhabitants.

You can safely choose the products of this brand, since this is one of the most thoughtful companies that has many options, and the company's consultants will select the option that suits you, taking into account the characteristics of your site and your needs.

The positive aspects of using the autonomous wastewater treatment plant "Topas" include:

• A wide product line, you can choose a model based on the number of people living, modifications have been developed for areas with a high level of groundwater, as well as a number of other interesting solutions,
• Increased strength of the product, squeezing the station with soil is excluded, extrusion is also impossible,
• Very easy to operate, easy to manage by yourself, and no need to spend money on maintenance,
• The station is silent
• A very high degree of water purification, which allows the discharge of water into reservoirs or into a gutter.

Among the minuses of the Topas brand stations are:

Choosing a septic tank for a private house
The article discusses general approaches to choosing a septic tank for a private house and summer cottage, as well as an overview of the Topas, Tank and Unilos models.

For operation in different conditions with individual nuances, there are different types septic tanks. When buying, it is desirable to know all these nuances for giving and a country house. What we will briefly discuss in this article.

For seasonal living in summer cottages and country houses, non-volatile septic tanks are perfect. These are models of septic tanks that do not require electricity. The following is a description of the main brands of such septic tanks.

Septic Tank

The tank is the most popular septic tank. The design of the septic tank is a block-module made of high-quality plastic, with overflow pipes. It is not pushed out by the soil thanks to special forms.

The principle of operation of the Tank is to preliminarily settle the waste water with its subsequent decomposition through a biofilter, which distributes the purified water into the soil.

Before winter, it is necessary to clean the septic tank from water so that freezing does not occur. The service life of this septic tank is 50 years.

Septic Triton

Triton - its design consists of chambers in which the process of decomposition of the biomaterial takes place, followed by filtration.

The volume of liters varies from 750 to 2000, depending on the model chosen. To strengthen the structure in its place, a concrete foundation is first poured.

Annually it is necessary to clean this septic tank from accumulations, and if it is used frequently, then at least 2 times. The term of use is 50 years.

Septic Bars-Bio

Bars-Bio - refers to the types of septic tanks for a private house. The uniqueness of this septic tank lies in its additional biofilter for wastewater treatment. Bars-Bio is a three-chamber equipment with two filters.

The flow of sewage in the chambers occurs at different levels, which allows you to retain your suspended particles in each compartment. The call for special equipment for pumping sediment from a septic tank is made no earlier than 1-2 years of use.

Designed for horizontal use, which is convenient for its installation. In order to avoid pushing Bars-Bio off the ground during installation, it needs to make a concrete shell.

The body of the septic tank can withstand both negative and positive outdoor temperatures.

How to choose the right septic tank for a private house

With permanent residence in a private house, there is a daily use of sewage, so the best septic tanks are volatile. These are bio septic tanks for a private house, powered by electric energy with aerobic wastewater treatment.

The main brands include:

Due to oxygen, bacteria are formed that decompose harmful substances onto biological material.

Types of septic tanks for a private house

There are signs by which it is customary to classify septic tanks, and also thanks to which you can choose the right septic tank for your home:

1. By way of work:

1. according to the material from which the case is made:

1. according to the location of the septic tank:

• horizontal- requires a large area for installation on the site. The advantage is that for such a septic tank the level of groundwater is not important.
• vertical- easy to install, perfect for giving. Takes up little space.

Now you know all the main characteristics of septic tanks for a good choice.

A bioseptic is a design that allows you to provide sewerage in a country house and purify wastewater. Comfortable living in the house in the absence of a centralized sewerage system is possible with the presence of a bioseptic tank, which is an autonomous sewerage system in the house.

What is a bioseptic

A bioseptic or biological treatment septic tank is a device that allows you to accumulate and purify wastewater. Such a system is a plastic tank that has high strength and several tanks for wastewater treatment. Cleaning is carried out due to the vital activity of bacteria.

Bioseptic and septic tank have several differences. First of all, they are different in that the bioseptic has an additional purification system using bacteria, air and other reactions that help purify water up to 95-98%.

Worth noticing that in bioseptics for wastewater treatment are used various ways cleaning, including mechanical, aerobic and biological cleaning. It is also necessary to pay attention to the fact that in a bioseptic tank, wastewater passes up to 8 degrees of purification.

The principle of operation of bioseptics

Worth noticing that the principle of operation of all septic systems is similar, despite the fact that their variety and quantity on the market is simply huge. All septic tanks work on the same principle.

The principle of operation of a bioseptic is to transfer water from one compartment to another, where various wastewater treatment processes are carried out. In the end, the water from the bioseptic becomes technical from the dirty one, and then it can be reused, for example, for irrigation.

A bioseptic is a system that has several cleaning compartments, usually equipped with a ribbed (hard) surface.

Wastewater first enters the first treatment chamber, where mechanical treatment takes place. In this compartment, water is purified from fats, surface-active substances (STEAM), which are part of almost all detergents, as well as large solid particles, which subsequently settle to the bottom. Further, still dirty water flows into the second compartment, where the liquid is re-cleaned, the sludge that is at the bottom flows back into the first compartment, the water is re-cleaned and settled.

After that, in small doses, it flows into the next compartment, where biological treatment takes place. At the end, the water flows into the next well, where the water settles for some more time and flows into a technical well (gutter).

Types of bioseptics

Bioseptics that I offer on the market can be divided into three categories regarding the material of their manufacture. This is how plastic, metal and reinforced concrete septic tanks for sewerage are distinguished.

Regarding the main component of bioseptics, it can be divided into:

1. Septic tanks that have biofilters;
2. Bacterial septic tanks.

Septic tank with biofilter

The septic tank, which has a biofilter, consists of a small filtration field where water is purified from organic substances that are in the drains. In the filtration compartment, cleaning takes place in two ways: mechanical and biological with the help of special bacteria. bacteria recycle organic matter into harmless inorganic ones, which makes the effluents cleaner and harmless. Biofilters can be of two types:

• Aerobic, which do not require ventilation and the participation of air in the process of passing reactions;
• Anaerobic ones require special ventilation and a constant supply of air.

Bacterial septic tank

In such septic tanks, biological substances and bacteria are the main component of the septic tank. Such a device allows you to process wastewater using bioenzymatic preparations in a biological way.

A bacterial self-contained sewer system is the best option for any home, as it does not require a lot of space for installation and additional tanks for cleaning.

Advantages and disadvantages of bioseptics

Biological septic tanks for wastewater treatment and storage have the following advantages:

• Environmental friendliness. Work without harm environment, and the hermetic base makes it impossible for contaminated water to enter the soil;
• Ease of operation;
• Autonomous work (does not involve other systems and means);
• Reliability and durability. The service life of a bioseptic is approximately 40-50 years;
• Easy to install and install;
• You can install such septic tanks in any soil and even in a small area;
• Purified water can be reused for watering the site, and sludge and sediment can be used as fertilizer;

As for the disadvantages, they are:

1. The cost of such a system.
2. Service and cost. Buying biologics and pumping out solid residues will cost the owner quite a lot.
3. Sewerage will have to be used constantly, since bacteria can die if the water stagnates.

Despite the shortcomings, such systems are quite popular in our time, as they are the best option for country houses.

In this article we will talk about deep biological treatment stations. We will describe the principle of their work, get acquainted with popular models and find out the average price tag for these high-tech facilities.

Bioksi septic tank is a station for deep biological treatment. Thanks to aeration, activated sludge, and fragmentation of pollution particles, this self-contained sewer system turns sewage into sludge and clean water. The quality of liquid purification reaches 98%. This means that water from a septic tank can go down a storm sewer, be used to water plants, or drain into water bodies.

This self-contained system consumes little electricity (up to 20 W per person), works silently due to the use of high-tech equipment, and is easy to install. The lid of the device comes to the surface of the earth, thanks to which you can control the cleaning processes. The septic tank does not require additional insulation, because its body is made of polypropylene. It also withstands any load of the soil, does not break or burst. The price for this type of sewer depends on the number of users and varies from 62,000 for the Bioxi 1 model to 240,000 for the Bioxi 5 model.

The Biozone septic tank is great for both country house, and for a cottage with permanent residence. The fundamental difference of this model is the formidable word bioreactor, which appears in the name of the model. Consider how the Biozon septic tank works.

Waste water with pollution enters the receiving chamber. There they are fractionated. Solid particles settle to the bottom, and the liquid rises up. In addition, a special filter for non-degradable waste is installed in the chamber. Scales, wool, hair, toilet paper and plastic, which are forbidden in other wells, are simply accumulated in the receiving chamber here. After they are pumped out using a sewage machine. This should be done every 3-4 years. Therefore, the costs are low.

The second chamber with a bioreactor is designed to purify fecal effluents with the help of bacteria and air. The Biozone septic tank has an airlift that circulates wastewater through the biofilter. It consists of layers of cellular modules in which colonies of microorganisms settle (for example, the Bioforce preparation). With the help of an airlift, water with activated sludge repeatedly passes through the reactor, where organic pollution decomposes. Oxygen, which is supplied by the compressor, contributes to the oxidation of dirt particles and their speedy processing. The output is pure liquid and carbon dioxide.

Biozone septic tank does not need to be preserved for the winter. The device of the bioreactor allows bacterial colonies to overwinter without air and new portions of wastewater. Therefore, at the end of the season, the electricity is turned off. Clean water that has passed through the Biozon septic tank can be used to water the garden, drain into a storm drain or nearby water bodies. The cleaning quality is 98%. Station prices start from 104,000 for a system for 2 people, up to 2,280,000 for 30-150 people.

Septic Bionic works on the principle of deep biological treatment. This product of domestic manufacturers decomposes fecal effluents using activated sludge and aerobic microorganisms. The aerotank is equipped with compressors and airlifts that pump fluid from one chamber to another. The Bionic septic tank is durable and reliable, the frame is made of polypropylene. Compressors and pumps (airlifts) work inside, so it is necessary to connect the station to electricity. The Bionic septic tank allows you to use purified water for agricultural needs, discharge it into ditches and water bodies without filtering through the soil. Installation prices start at 98,000 (capacity for 4 people) and range up to 190,000 (capacity for 15 users).

For those who have problems with electricity in a private house, it is recommended to purchase a non-volatile autonomous sewer. A good option would be to install Biostock. It is a three-chamber container where liquid and waste are accumulated, filtered, processed by anaerobic organisms. This produces detritus, water and gases. To remove them, a ventilation system is built into the Biostok system. The overflow pipes are installed in such a way that sedimentation is very slow. At the outlet of the Biostock system, infiltrators or filtration fields should be installed.

What are the advantages of such septic tanks? Biostok can work without electricity. This is his main merit. Such systems have a lower price tag than deep biological treatment plants. For example, Biostok-1 plus an infiltrator will cost only 27,000. And a system for seven residents will cost as the simplest septic tank for deep biological treatment.

The disadvantages of the well are the need for soil post-treatment. This requires large-scale earthworks, laying additional layers of filter material. In general, Biostok can be used for giving and at home. After all, inside the system is stored heat allowing her to survive the winter.

For a private cottage or a site with rocky soil, the Biopurit system is perfect. The body of this station is made of fiberglass, has a cylindrical shape and increased resistance to mechanical movements of the soil. The system works on the principle of an aeration tank, the bacterial filter is fixed in the second tank. Therefore, bacteria are not washed out of the reservoir. Biopurite works in the presence of electricity, but when the network is turned off, the septic tank goes offline and works on the principle of an overflow system. The power supply, which is located inside the structure for many stations, is located on the cover here. This protects the wiring from moisture. It is possible to move the unit inside the house.

For any deep cleaning station, the problem of clogging is relevant. Manufacturers of Biopurit have solved this problem by increasing the size of the overflow pipes. The possibility of an emergency stop due to the ingress of paper or hygiene products into the system has decreased significantly. By the way, the Biopurit system is pumped out once a year only from the sump. This saves you money.

Now let's talk about prices. The price tag for Biopurite for a small family will be 55,800 rubles. For a sanatorium or a small hotel, such a system will cost 849,000 rubles. As you can see, with visible advantages, Biopurite remains in the middle price category.

Septic tank NT Bio

HT bio is a deep biological treatment plant. We list its main characteristics.

• The body of the NT bio is made of polyethylene, a cheap material that is resistant to corrosion. However, if the house has rocky ground, it is better to use more durable plastics;
• Works NT bio from electricity, but is resistant to disconnection from the network;
• Allows you to endure the winter without complete pumping and in the absence of effluent;
• NT bio is sealed and odorless, which is especially important for a private home;
• Only one compressor is installed in the system, which saves on electricity and maintenance;
• NT bio does not require soil post-treatment. Water is drained into a storm sewer or well, and then used for agricultural needs.

The price tag for NT systems starts at 72,000 rubles.

Eurolos is a budget septic tank with a deep biological treatment system. In the center is a bioreactor where microorganisms are loaded. This allows you to create a stable population in the Evrolos station, which easily endures the winter period and the lack of runoff.

The main advantages of the system:

• In the Eurolos tank, wastewater is repeatedly passed through a biofilter, which achieves a high degree of purification;
• Inactive sludge from the well can be pumped out independently. It is harmless and can be used as fertilizer;
• The cylindrical shape of the Eurolos hull speeds up installation and protects against overloads during ground movements;
• The septic tank does not require frequent maintenance. Service is needed every 2 years;
• When the power is turned off, the autonomous sewage system Eurolos bio starts working as an overflow septic tank.

Such a system is suitable for a small cottage and a large private house. Prices for Eurolos installation start at 57,000 rubles.

Septic Biodeca

This system does not have an aeration tank, and activated sludge is used as an active substance. Consider the main advantages of the Biodek septic tank:

• The system is resistant to both a small amount of waste and a massive salvo discharge. Indeed, this does not have any effect on the concentration of activated sludge;
• The well does not spread unpleasant odors, since there is no anaerobic microflora inside the station;
• The quality of wastewater treatment in the Biodek system reaches 98%;
• Station maintenance work can be carried out independently;
• Bacteria are not loaded into the Biodek system, which eliminates unnecessary costs;
• The septic tank works quite economically and does not consume a lot of electricity.

Biodeka deep biological treatment station can be purchased for 65,900 rubles. As the number of users increases, the price goes up.

Financial opportunities. The most budgetary autonomous sewage system is the Topas and Tank septic tank. By their own technical specifications they are not much inferior to foreign devices and at the same time much cheaper.

Seasonality of use. If you plan to live in a residential building permanently, it is best to purchase septic tanks that are not difficult to maintain and are non-volatile.
