Overview of the septic tank for giving "Tank": how it works, the advantages and disadvantages of the system

Principle of operation

The scheme of operation of a septic tank practically does not differ from other similar devices. With the help of the inlet pipe, sewage from the sewer enters the primary filtration compartment. There, through the use of filters and an aerator, the drains are cleaned of solid waste that accumulates in the lower part of the well. The aerator saturates moisture with oxygen for more effective work of bacteria and provides getting rid of unpleasant smells.

After the compressor pumps water to the next section - the aeration tank. Here the separation of liquid waste, sludge and moisture is carried out. The sludge is screened to the bottom of the compartment, liquid effluents are cleaned with a finer filter. A notable feature of the sludge pumping system is that it is transported to the primary compartment.This allows you to clean the septic tank only in the first chamber.

After the aeration tank, the water is pumped to the secondary sump, where its cleaning is completed. After that, the liquid can be used for irrigation, as technical or in other needs.

According to the manufacturer's recommendations, maintenance of the Poplar septic tank is optional (but only on condition that the operating instructions are followed):

1. The septic tank can be connected with your own hands, without the involvement of specialists. But it should be located on a sand cushion that protects the device and the case from the effects of external factors (temperature changes, earth pressure, etc.). The minimum backfill level on each side is 250 mm, while the height of the cover above the ground should not exceed 200 mm;

2. The manufacturing company has a very strict requirement for the use of a treatment station: the system cannot be used to treat wastewater containing polyethylene and other films, aggressive chemicals and metal particles. This may affect the quality of filters and compressors;
3. Before the first start, the container is filled with clean water to provide the right environment for the life of bacteria.

Feedback from the owners of Poplar Eco-Grand is positive. Most owners of the system are inclined to believe that this septic tank is the best combination of price and quality.

The entire system is cleaned twice a year - after the winter and summer seasons. Regardless of the operation of the sump and compressors, it is recommended at least once a month to inspect the working mechanisms, filters and check them for the presence of litter.

Preparatory work

The dimensions of the pit prepared for installation are determined by its dimensions of the treatment plant. The body should not stand close to the walls of the pit. It is necessary that the gap between the wall of the septic tank body and the side of the pit is 25-30 cm.

The list of measures for the further preparation of the pit depends on the depth at which the soil water occurs. So, if the groundwater lies deep, then it will be enough to make a pillow of sand at the bottom. Sand is poured in a layer of 30 cm and well compacted.

In high-lying waters, additional protection measures will have to be taken. In this case it is necessary:

• make a sand cushion at the bottom of the pit, as described above;
• lay a reinforced concrete slab on top of the sand or fill the bottom of the pit with a cement mortar using embedded metal parts;
• after installing the septic tank, you will need to fix it on the stove with bandage straps.

How is the DKS septic tank arranged and how does it work?

The production of septic tanks of this brand is organized by the developer from sheet polypropylene, the thickness of which varies from 5 to 8 mm.

The design can be roughly divided into three main parts:

• I chamber serves as a primary sump;
• II chamber given under the secondary sump;
• Chamber III is used to accommodate the biofilter.

Through the inlet pipe (1), wastewater enters the primary sedimentation tank and is separated in it into heavy (3) and light (2) fractions. Overflow (4), connecting the primary and secondary clarifiers, is located at the level of one third of the height of the tanks. Due to this arrangement in the second chamber, the content of impurities in domestic wastewater is noticeably less than in the first. At the same time, the process of sedimentation and clarification of sewage water continues in the second chamber.

The septic tank "DKS" consists of three chambers, in two of which sewage is settled and solid particles are split. Biofilter installed in the third chamber

In the tanks of the septic tank, along with the mechanical separation of impurities, the process of their anaerobic fermentation takes place, while the presence of oxygen is not required. During the reaction, methane is released, so often such structures are called methane tanks. Methanogenic bacteria present in faeces are involved in the decomposition of contaminants during metabolism.

The spread of an unpleasant odor from the location of the septic tank is prevented by water locks that reliably block both settling chambers.

Further movement of clarified wastewater inside the septic tank goes through the overflow pipe (5) to the biofilter, while their mixing and disturbance is excluded. With the help of a removable drip sprayer installed on the overflow pipe, there is a uniform distribution of water throughout the brush load (7). Previously, the manufacturer used expanded clay loading instead of ruffs. On the surface of the ruffs, the water is saturated with oxygen, therefore, an aerobic bioflora is formed, which develops well in favorable conditions.

The correct operation of the biofilter is ensured by a pipe with a head (9), through which air enters, which is necessary to maintain the vital activity of aerobic microorganisms.

The effluents passed through the biofilter enter the drainage system (11), while bypassing the sump (8) and the outlet pipe, indicated at number 10 in the diagram. A perforated pipe is used as a drainage system in the above diagram, through the holes of which clarified soil where they undergo final infiltration.Through the neck (12) periodically remove the sediment accumulated at the bottom of the first and second chambers. The revision and maintenance of the septic tank is carried out through the second neck (13).

In winter, to prevent freezing of containers, the manufacturer recommends deepening the structure using the neck extension kit shown in the diagram at number 14. This kit is purchased additionally if necessary.

How a septic tank works

Tank septic tanks have long occupied a leading position in the market, and the most interesting thing is that they achieve such popularity not only due to excellent quality, but also largely due to a more affordable price. These products are produced in Russia, so transportation costs are greatly reduced. However, the principle of operation of the Tank septic tank plays the greatest role in the formation of a more affordable price. For wastewater treatment, most Tank models use a very simple filtration principle that works completely autonomously. Almost all tank septic tanks are not volatile. Immediately after their installation, you can completely forget about sewage for the next six months and enjoy all its amenities. After six months, you will only have to clean the septic tank.

It is immediately worth noting that recently there have been more and more new models of septic tanks from this manufacturer. The principle of operation of some of them differs markedly from the functions of standard designs.

On what principle do classic tank septic tanks work?

By what principle classic septic tanks work Tank?

Classic septic tanks Tank are a standard multi-chamber design. Such systems are often called settling tanks, because it is precisely due to this principle that they work.

Sewer waste first enters the first chamber of the system. There, heavier impurities settle to the bottom, and the liquid part of the waste remains on top. As soon as the filling level of the first chamber rises to a certain level, the top layer passes into the next compartment of the septic tank. There, the process of flaking waste is repeated.

As a result, after the second chamber, wastewater becomes cleaner by 60-70%, and after the third - by 95-98%. A three-chamber design will be enough to safely drain the treated water into deep soil layers. Due to this, the septic tank is gradually self-cleaning, and that is why it will be necessary to pump out waste from it only once every six months. After this time, the sludge will reach such a size that it will already interfere with the operation of the system.

How a septic tank works

The principle of operation of the septic tank Tank does not allow the use of classic two-chamber designs without additional devices. As already mentioned, such systems purify wastewater only by 60%, and this is not enough. Draining such a liquid into the soil can lead to groundwater poisoning, which will cause not only you, but all your neighbors to suffer in the future. Therefore, a two-chamber septic tank Tank is recommended to be purchased in combination with infiltrators.

An infiltrator is a device that no longer collects wastewater, but conducts it through a filter layer. As a result, the water is already purified to a sufficient level. In some cases, it can even be reused. Often summer residents take advantage of this opportunity. Purified water they use for watering plants.

On what principle do Biotank septic tanks work?

BionTank septic tanks are more compact and work somewhat faster. This is achieved by forced cleaning of wastewater in some of the chambers of the system.

BioTank septic tanks consist of four chambers. In the first three, a natural cleaning process takes place, as in other systems. True, in this design an aerator is used, and compresses constantly direct fresh air in the right direction. Of course, because of this, you can lose some of the advantages of Tank systems. The BioTank septic tank already depends on electricity, but it works much faster.

A constant supply of oxygen stimulates the work of aerobic bacteria. They feed on organic waste, making waste water more liquid and uniform. In this state, the waste is easier to separate into layers. After passing through the three chambers of the system, the water already becomes quite clean, but the process of its processing does not end there.

The fourth chamber of the BioTank uses an additional filter. Due to this, such systems no longer need additional devices. They can filter the water well on their own.

Septic Tank

Autonomous modern installation The tank consists of several tanks. Each container is divided into compartments by partitions. This may be one or more compartments for settling wastewater and a biological filter. The advantage of the design is that by connecting additional containers, the capacity of the septic tank can be increased to the desired volume.

Assembly system for treatment plant models The tank is modular, and polypropylene is used for the production of treatment tanks. Tanks easily withstand ground pressure due to elastic, thick, ribbed walls.In operation, the design of the Tank is distinguished by reliability, durability and simplicity. If you need a quality construction for a reasonable amount, choose the installation of a tank septic tank.

In addition to the basic configuration, infiltrators can be ordered. They will additionally treat wastewater before draining it into the ground. There is a small fee for this set.

To install a septic tank on the site, you will not need additional labor or equipment. The containers are light and small in size. A pit can be dug by one person in a short period of time. Due to its small size, the Tank septic tank can be installed almost anywhere on the site. Only the ventilation pipes and the auditor's hatch will be visible on the surface of the earth.

To clean the structure itself from the remnants of sewer water, you need to call a team of sewers. It is advisable to do this at least once a year. The models of the Tank septic tank produced in the factories differ in the size of the main tank.

Note! Whatever model of Tank septic tank you buy, its dimensions and capacity can be increased by auxiliary tanks. Any model can be equipped with additional filters

Criteria for choosing a septic tank for non-permanent residence in the country

A septic tank is an equipment that allows you to clean sewage waste from your home. They process small volumes especially well. Systems are installed underground

An important design feature of a septic tank is the installation of drainage

When choosing a septic tank for a summer residence, the number of people who will live in the household is of decisive importance. This will allow you to calculate the required volume.If the unit will be used for non-permanent residence, you should prefer standard country septic tanks that provide anaerobic cleaning.

To find a model that meets the needs of non-permanently living people in the country, it is recommended to pay attention to the following factors:

1. Required performance indicator. For one person, the volume of 150-200 liters per day is calculated.
2. Equipment with electricity.
3. Plot settings. For autonomous type structures, a large area is required, since soil filtration fields are installed.
4. The passage of groundwater. Depending on their proximity, it may be necessary to install additional engineering systems.
5. Soil features. For territories with solid soil, country septic tanks are used, for non-permanent residence, made in a horizontal position, since shallow pits are required for their arrangement.

To effectively treat contaminants, a septic tank should have 20-25% headroom. If the budget is minimal and the cottage is not planned to be used all year round, you can stop at a container with a volume of up to 10 m2. A factory-built station is more reliable than a self-assembled station.

An important point when purchasing a septic tank for giving non-permanent residence are the methods for withdrawing sewage - we offer you to learn more about how to make a sewer in a country house with your own hands. Discharge can be made through wells, which are equipped with filters made of crushed stone and sand. Systems are relevant in areas where groundwater passes far from the surface.

In areas with a rocky surface, the discharge is carried out into a central sewer. With this option, the purification rates should not be less than 97-98%.

Also, discharge can be carried out into the intermediate compartment, and then into the ground. For this, drainage devices are used. The treated liquid can be used for technical needs.

For storage for a short period of time, a well with storage functions is suitable. In winter, the sewer pipe should be installed below the freezing level of the soil.

An important point is the number of tanks. If the flow rate is less than one cube per day, then one camera will be needed. If more than 1 but less than 10, you should choose a device with two bays. Multi-chamber septic tanks for giving non-permanent residence are suitable with a volume of more than 10 cubic meters.

Some information about the manufacturer

The most popular Tank model in the domestic market is produced by Triton Plastic LLC. This company is today one of the largest manufacturers of energy-independent treatment structures. She also produces various plastic products, without which it would be difficult to achieve a comfortable environment in a country house.

Having a fairly developed dealer network, as well as its own warehouses in many regions of the country, the company was able to ensure the supply of its products to the most remote corners of Russia. One of its brainchildren is the Tank 3 product, which appeared thanks to the professionalism of the employees and the extensive experience in the production of such products.

watch the video, the production of this model:

The company's own design department allowed us to quickly process all requests and calculate the cost of products. At the same time, the quality of each product is checked in the technical control department, so the company's models are highly reliable and efficient.The presence of modern equipment at the production facilities allows us to produce plastic products of any complexity.

Design and principle of operation

A septic tank looks like a large plastic cube with a ribbed surface and a neck (or two) sticking out above the surface. Inside, it is divided into three compartments, in which wastewater is treated.

The body of this septic tank is one-piece cast, it has no seams. There are seams only at the neckline. This seam is welded, almost monolithic - 96%.

Septic tank: appearance

Although the case is plastic, it is definitely not fragile - a decent wall thickness (10 mm) and additional even thicker ribs (17 mm) add strength. Interestingly, when installing a septic tank, the Tank does not require a plate and anchoring. At the same time, even with a high level of groundwater, this installation does not emerge, but this is subject to the installation requirements (more on them below).

Another design feature is the modular structure. That is, if you already have such an installation, and found that its volume is not enough for you, just install another section next to it, connect it to the already working one.

The modular structure allows you to increase the capacity of the Tank septic tank at any time

Principle of operation

A septic tank works in the same way as many other similar installations. The procedure for wastewater treatment is as follows:

• Water draining from the house enters the receiving compartment. It has the largest volume. While it is filling, the waste decomposes, roams. The process is carried out with the help of bacteria that are contained in the waste itself, and good conditions are simply created in the tank for their vital activity.During the cleaning process, solid sediments fall to the bottom, where they are gradually pressed. Lighter fat-containing dirt particles rise up, forming a film on the surface. The more or less pure water located in the middle part (purification at this stage is approximately 40%) enters the second chamber through the overflow hole.
• In the second compartment, the process continues. The result is a cleansing of another 15-20%.

• The third chamber has a biofilter at the top. In it there is an additional treatment of effluents up to 75%. Through the overflow hole, water is discharged from the septic tank for further purification (into the filter column, into the filtration fields - depending on the type of soil and groundwater level).

Not a bad exit

As you can see, there are no difficulties. With proper installation and operation, the Tank septic tank works flawlessly - it does not depend on electricity, so it is not afraid of frequent power outages in rural areas. Also, the installation tolerates an uneven usage schedule, which is typical for summer cottages. In this case, the flow of effluents on weekdays, as a rule, is minimal or absent, and reaches a maximum on weekends. Such a work schedule does not affect the cleaning result in any way.

The only thing that is necessary for dachas is conservation for the winter, if accommodation is not planned. To do this, it is necessary to pump out the silt, fill all the containers with water by 2/3, insulate the top well (fill in leaves, tops, etc.). In this form, you can leave to winter.

Operation features

Like any septic tank, the Tank does not respond well to a large amount of active chemicals - a one-time supply of a large amount of water with bleach or a chlorine-containing drug kills bacteria.Accordingly, the quality of purification deteriorates, an odor may appear (it is absent during normal operation). The way out is to wait until the bacteria multiply or add them forcibly (bacteria for septic tanks are commercially available).

Another of the features that must be taken into account is not to flush waste into the sewer that does not decompose by bacteria. As a rule, these are wastes that appear during repairs. Not only can they clog the sewer, and you will have to clean it, but these particles significantly increase the amount of sludge, and you will have to clean the Tank septic tank more often.

Varieties of designs and model range

To understand the principles of operation of a Topas-type septic tank, you should study its design. Externally, this device is a large cube-shaped container with a large square lid.

Inside, it is divided into four functional sections. There is a built-in device for air intake from the surface to ensure the saturation of the effluent with oxygen.

The Topas septic tank consists of four interconnected chambers providing multi-stage cleaning. Flowing from one compartment to another, the effluents are settled, processed by bacteria, disinfected and clarified

Inside the cleaning system are the following elements:

• the receiving chamber, into which the effluents initially enter;
• airlift with pumping equipment, which ensures the movement of wastewater between different departments of the device;
• aeration tank - a department in which the secondary stage of cleaning is performed;
• pyramidal chamber, where the final treatment of wastewater takes place;
• post-treatment chamber, here the water purified during the operation of the septic tank accumulates;
• air compressor;
• sludge removal hose;
• device for the removal of purified water.

The range of septic tanks of this brand is quite wide. There are models for plots and houses of various sizes, devices designed to service gas stations, and even powerful sewage treatment plants that can meet the needs of a small village.

This diagram clearly shows the device of the Topas septic tank. It consists of four different departments, through which the waste that has entered the sewer pipe is moved.

In private housing construction, Topas-5 and Topas-8 septic tanks are most often used. The number next to the name indicates the approximate number of residents that the device is designed to serve.

"Topas-5" has a more compact size and lower productivity, it is able to easily meet the needs of a family of five in sewerage services.

This model is considered an ideal choice for a relatively small cottage. Such a device can process about 1000 liters of wastewater per day, and the simultaneous discharge of waste within 220 liters will not cause any harm to the septic tank.

The dimensions of Topas-5 are 2500X1100X1200 mm, and the weight is 230 kg. The power consumption of the device is 1.5 kW per day.

But for a large cottage, it’s better to take Topas-8. The dimensions and ability to process wastewater from this model are much higher. Such a septic tank is able to serve even the areas where the pool is located, although in such a situation, Topas-10 may be more appropriate.

The performance of such models varies between 1500-2000 liters of wastewater per day.

The numbers next to the name of the septic tank indicate the number of people that this device can serve with simultaneous use. Buyers are guided by these indicators, choosing the right model.

There is also a letter marking that describes the special operating conditions for which a particular device is designed.

For example, the designation “Long” indicates the possibility of using this septic tank with a connection depth that exceeds 80 cm. The “Pr” marking indicates models with the option of forced pumping of partially treated water.

Such designs are additionally equipped with a pump. Models marked "Pr" are used in areas with a high level of groundwater.

Models of Topas septic tanks may vary depending on the volume of wastewater being processed, as well as on operating conditions. For example, for areas with an elevated groundwater level, it is recommended to choose a septic tank marked “Pr”

The presence of a pump in the device of this model of the Topas septic tank is designed for installation on a site with clay soils that do not filter well or do not absorb purified water at all. Marking "Us" stands for simply - "reinforced".

These are more powerful models that should be used if the installation depth of the septic tank exceeds the level of the sewer pipe by 1.4 m or more.

The higher the performance of the pump, its power and the more options it has, the more expensive it will be to purchase it, and the more difficult it is to install it. Therefore, you should not choose a treatment plant “for growth”, if in the near future the number of residents in the house should not increase sharply.

More detailed recommendations on choosing a septic tank for a summer residence are discussed in our other article.

Overview of septic tank models

Manufacturers offer a septic tank in five versions. Let us consider in detail the device of each, its advantages and disadvantages.

• "Tank 1". The septic tank is designed to serve a family of three. The capacity of the septic tank is 600 liters per day. As an option - seasonal use for a family of 5 people;
• "Tank 2". Possibility of water purification from 4 permanent residents. Processing of wastewater per day reaches 800 liters;
• "Tank 2.5". Serving five permanent residents. Production reaches 1000 l;
• "Tank 3". Productivity - 1200 liters of water per day from a family of six people;
• "Tank 4" can clean drains from a family of 9 with a volume of 1800 liters. The station can be organized to receive sewage water directed from several houses.

Tank 1

Miniature septic tanks to serve the seasonal or permanent residence of three people. A septic tank can be used as a container for a storm water reception device. The tank is made of high-strength polyethylene, it can be used at sub-zero temperatures.

Advantages of a septic tank Tank 1.

• mobile dimensions do not interfere with the efficient operation of the sewerage system;
• low price;
• maintenance is not required.

Tank 2

The station is produced in two versions: accumulative and three-chamber. Accumulative septic tank The tank is used only for the accumulation of sewer masses. A three-chamber station is arranged for autonomous treatment of domestic wastewater. Gradually moving through three reservoirs, wastewater is cleared of suspension and solid particles.

Advantages.

• septic tank The tank can be completed with the missing sections to increase the volume of sewage treatment;
• the design is quite reliable;
• the station is made with an elongated neck, which allows its installation at great depths;
• simple device;
• the septic tank is non-volatile;
• low price.

Flaws.

without additional post-treatment, the station purifies wastewater only up to 75%.

Tank 3

The septic tank embodies all the best production parameters of stations of similar series. The product is high tech.

Advantages.

• the septic tank consists of blocks, which allows you to supplement the missing modules to increase productivity;
• high degree of purification. With the device of an additional infiltrate - purification reaches 100%. This has a positive effect on the ecology of the soil;
• simple installation, a simple septic tank device does not require engineering skills during installation;
• the station is completely autonomous;
• there are no nodes in the septic tank that can fail;
• The tanks are made of high-strength plastic and can withstand high pressure.

Tank 4

Septic tank with increased productivity. In addition, it is possible to increase the volume of sewage water by supplementing it with chambers.

In the first tank, the wastewater settles, screening out the largest particles.

With the help of bacteria, the fermentation process begins, which is accompanied by the release of gas. To remove the gas flow, it is necessary to make a ventilation pipe.

Stock masses smoothly flow into the second chamber for secondary release from suspensions and small debris.

The third stage of purification takes place in the separator.

This is the most powerful equipment in the entire line of Tank septic tank models. It can be installed at industrial facilities, country cottages.

To increase power, you just need to buy tanks of the required volume and attach them to the main structure.

Advantages and disadvantages of the septic tank "Tank"

Non-volatile septic tanks "Tank" are optimally suited for the installation of an autonomous sewer cleaning system in any private house. It is especially expedient to equip them in the areas of country and country houses of seasonal or periodic residence, as well as in areas with frequent power outages.

Installation of the system is not complicated and is often done independently. This allows you to save an amount equal to the cost of the septic tank itself.

Local communications that do not require electricity for operation are also used in the construction of energy-saving buildings. Technologies that allow saving resources are becoming increasingly popular.

Advantages of these septic tanks:

• Simple and reliable design, which is practically not subject to wear;
• The sealed and durable body of the septic tank withstands the damaging effects of the environment and ensures reliable operation of the system;
• The absence of components requiring periodic maintenance or repair;
• The ability to provide any required performance by adding additional modules, which can even be connected to a functioning system;
• The sewerage system, which combines the Tank septic tank and the additional filtration device, provides complete purification of wastewater from pollution - up to 98%;
• The service life is at least 50 years;
• The compact body of a convenient rectangular shape and the low weight of the structure allow you to install the septic tank on your own, without the involvement of specialists;
• All maintenance of the cleaning system based on the septic tank Tank consists in calling a vacuum cleaner once a year;
• Acceptable price.

Septic Tank is one of the most unpretentious in operation. Toilet paper, food debris and a reasonable amount of household cleaners and detergents are allowed to enter the system.

Step 1: Before installing a septic tank, we develop a pit, the bottom of which we fill with sand and carefully ram

Step 2: On a compacted and leveled bottom, we install a sewer structure corresponding to the calculated value of water consumption for three days

Step 3: We connect elastic adapters to the pipes of the septic tank Tank, which ensure a tight connection of the incoming and outgoing sewer line

Step 4: In a pre-designed trench, we lay sewer pipes, which we enter and withdraw from the tank septic tank

Step 5: Components of the sewer system located above the level of seasonal freezing of soils are insulated with a material that does not absorb moisture

Step 6: Having filled the sewer tank with water so that when backfilling the soil does not deform the walls, we fill the pit. In areas with low groundwater, we fill it with earth dumped during development, in places with characteristic floods - with a sand-cement mixture

Step 7: To install infiltrators, we dig a separate pit, the bottom of which is lined with geotextiles and covered with rubble

Step 8: On the ground built for infiltrators geotextile filter and crushed stone we put the required number of these devices, connect to the septic tank, install ventilation pipes and fill the system with earth

However, like any engineering design, the Tank septic tank has not only advantages, but also disadvantages.

• According to sanitary standards, the water leaving the septic tank cannot be drained into the ground - a gravel-sand or gravel-sand filter is used to clean it up;
• Installation flaws lead to the appearance of an unpleasant smell in the house coming from the sewer;
• The sludge accumulated in the tank cannot be used as fertilizer, as it may contain organic residues and harmful substances that can cause contamination of the soil and groundwater.

To prevent the appearance of odors in the house, a ventilation riser must be built into the supply pipeline. Anaerobic bacteria during the processing of wastewater emit methane, so the gases must be diverted. Also, when installing the tank, it should not be warped.

To remove methane associated with the processing of wastewater by anaerobic bacteria, ventilation risers are installed. They are installed at the inlet to the purification system and at the outlet of the infiltrator (+)
