How the Tver septic tank is installed: an overview of the installation technology

Installation and maintenance of a septic tank Tver

To install a cleaning system, you can invite specialists or do it yourself.

It is very important to choose the right place for the location of the equipment and dig a pit corresponding to its size. In this case, the dimensions of the trench should be made thirty centimeters larger than the dimensions of the installation.

The bottom of the excavated pit is covered with cement-sand mortar, the septic tank is installed and fixed. After that, sewer pipes and electricity are connected.

When everything is installed and connected, the septic tank will need to be additionally covered with a mixture of cement and sand, while simultaneously filling it with water.This will protect the station from possible damage.

When installing a septic tank, it is necessary to strictly follow all the instructions and take into account the features of the site. Therefore, it is better to entrust the installation of such equipment to professionals who will give a guarantee for their work.

Maintenance Tips

A septic tank, like any other device, needs regular maintenance. For its good continuous operation it is required:

• periodically check the operation of compressors that are responsible for the quality of effluents;
• remove accumulated sediment annually.

During the operation of the station it is prohibited:

• throw away children's diapers, rubber and plastic products, plastic bags, various construction waste and other objects that do not decompose under the influence of bacteria into the sewer;
• pour paints, thinner, gasoline and other caustic and toxic liquids into the system.

Subject to all these requirements, the Tver septic tank will provide the sewer system with the highest possible level of wastewater treatment and will work effectively for many years.

Installation and maintenance of a septic tank

Mounting the device

The instruction of the septic tank "Tver", supplied with the device itself, describes in detail the installation process. To install the equipment you will need:

• sand;
• dry cement;
• power supply.

Installation of septic tanks "Tver" can be done independently or with the involvement of specialists.

To install the equipment on your own, you need:

1. dig a pit slightly larger than the dimensions of the device;
2. make a sand embankment at the bottom of the pit. The sand is carefully compacted and spilled with water;

1. insulate the top of the septic tank. For this, you can use any material, for example, mineral wool;

The upper part of the product must be insulated

1. make the final backfill. The installation of the septic tank "Tver" is considered complete.

Final backfill

Equipment installation work must be carried out carefully and carefully. Allowing even a slight misalignment during installation can lead to incorrect operation of the device.

Device maintenance

The maintenance of the Tver septic tank consists in carrying out regular preventive maintenance and complete cleaning of the equipment.

Preventive work

Regular prevention work equipment include:

removal of excess sludge from the chambers. For this, fecal pumps or specialized equipment are used. Pumped out sludge can be used as fertilizer;

Removal of sludge with a cesspool machine

filter cleaning. In the bioreactor of the equipment there are brush filters that require regular cleaning. They are easily removed and washed well with ordinary running water. Next, the filters are installed in place. There are situations when the beams supporting the filters rot.In this case, a complete replacement of metal elements is required;

Removing filters for flushing

replenishment of bacteria and limestone.

Preventive work is recommended to be carried out once every 2-3 years, depending on the intensity of use of the equipment.

Carrying out a complete cleaning

To carry out a complete cleaning of the septic tank, you will need:

• fecal pump or sewage equipment;
• high pressure washer.

Cleaning work is carried out as follows:

1. Remove the top cover from the equipment. This gives access to three taps located inside the device;
2. in the working position, the end valves are closed, and the middle one is open. Through the middle valve, oxygen is supplied to the compartment. To start pumping sludge from neighboring compartments, it is required to close the middle valve and open the end valves one by one. The average operating time of one crane is 15 - 20 minutes. After this procedure, the sludge from adjacent compartments will move to the central one, from which it must be removed by a pump or machine;

Equipment open for full cleaning

1. further, ruff filters are removed from the bioreactor and washed thoroughly. Supporting metal elements are replaced;
2. The pressure washer is used to clean the walls of the septic tank. After that, excess liquid is removed by a pump;

Flushing a septic tank

1. removed equipment is installed in its place. Bacteria and limestone are backfilled;

Installing filters

1. the middle tap opens and the lid closes.

Complete cleaning of the septic tank is carried out at least once every 5-7 years.

Design features

The device of the Tver septic tank (shown in the figure below) helps to remove heavy fractions from wastewater, destroy the structures of various formations, and also provides accelerated biological treatment.

Simplified scheme-design of a septic tank

Designations indicated:

• A - biological reactor;
• B - settling tanks;
• C - biological reactor with aerator;
• D - aerators;
• E - limestone;
• F - sand;
• G - soil;
• H - aeration tank.

The first settling tank is a septic tank, it is in it that the separation of heavy fractions takes place, which settle to the bottom. Some of them dissolve after a while and enter the next chamber.

Waters purified from heavy fractions enter the aerotank, where they are actively saturated with oxygen, which creates favorable conditions for bacteria that decompose biological waste

The capacity of the septic tank Tver is divided into several compartments, their purpose and principle of operation is as follows:

• storage tank, drains enter it, the insoluble mixtures contained in them settle to the bottom. After a certain time, some of them dissolve and go to the next compartment;
• chamber with anaerobic properties. It serves for mechanical destruction of solid fractions that have not settled to the bottom. This occurs in the process of passing through special structural elements, as well as due to fermentation under the influence of microorganisms with anaerobic properties;
• the aerotank compartment saturates the contents with oxygen, which allows aerobic microorganisms to multiply intensively;
• the settling chamber serves to retain heavy fractions, due to which the biological decomposition of organic substances contained in the drain is accelerated;
• the compartment of the aerobic biological reactor contributes to the process of absorption of organics by microorganisms.In addition, due to the gradual dissolution of limestone contained at the bottom, toxic compounds are bound, which include phosphorus and nitrogen;
• the sump chamber of the “calmener” completes the cleaning stage; at the outlet of it, the water is purified by at least 95%. In the same compartment are floats for disinfection, which contain chlorine reagents.

A complete technical description of the models (volume, performance, equipment, etc.), as well as their comparison and prices, will be provided to you by regional dealers, who will also advise which septic tank will be the most optimal.

The septic tank Tver combines all three possible wastewater treatment technologies. In the first - receiving - compartment, mechanical cleaning takes place, as is customary for classic septic tanks. In the other two - aeration and processing of wastewater by aerobic microorganisms, as in aeration plants (AU) and in two - processing by anaerobic (without oxygen), and there is also a biofilter at the outlet, which completes the purification. This is such a complex system, but according to the assurances of the manufacturers, 98% purified water comes out and it can be dumped directly onto the ground or diverted into a reservoir.

Septic tank Tver from the inside

The Tver septic tank differs from other installations for an autonomous sewage device in its horizontal layout - successively arranged compartments in which water is poured. Her device can be seen in the photo below.

The device of the septic tank Tver

The cleaning procedure is as follows:

• Effluent enters the first tank - a septic tank. In it, as in a classic septic tank, heavy particles settle to the bottom, light, fat-containing ones rise.
• From this chamber, through the upper overflow, wastewater enters the second compartment - an anaerobic bioreactor. In this chamber there are ruffs on which colonies of microorganisms multiply. Here bacteria process particles that are difficult to oxidize. In parallel, the remaining contamination continues to settle/float.
• After processing, wastewater enters the aerotank with aerobic bacteria. The pump supplies air here to ensure their vital activity. At the bottom of this chamber is expanded clay, which breaks the air into small bubbles. The activated sludge accumulated at the bottom, which processes wastewater, is mixed with water by streams of air bubbles. Bacteria actively convert organic residues, the degree of purification becomes even higher.
• The next compartment is a sump where contaminants settle/float. The settled sludge, due to the original structure of the walls, falls back into the aerotank.
• Already sufficiently pure water from the sump enters the second aerotank with ruffs, where the purification is completed. There is limestone rubble, which binds phosphorus. It is difficult to remove it in other ways and few people worry about it.
• The last stage is the third settling tank, where sludge settles again and clean water is separated.
• A chlorine cartridge is installed at the outlet of the Tver septic tank. This is a cylindrical device made of porous material.Inside it is a mixture of chlorine and sand. After that, the water can be dumped onto the relief - it has neither color nor smell.

Not to say that the process is simple, there are many nuances, but the cleaning result is not bad and the installation does not require daily attention, it works stably.

The process of building a budget septic tank from concrete rings is described here.

Advantages and disadvantages of the treatment system

Tver septic tanks have advantages and disadvantages, like any technical device. However, the number of pluses significantly outweighs, due to which these treatment facilities are widely and successfully used.

Design advantages:

• Complete water purification takes place in one tank - no additional additional filtration devices are required.
• A septic tank with a properly selected capacity cleans up 98% of wastewater - such water can be discharged onto the terrain, into a reservoir, and used for household needs.
• The body of the septic tank is made of high-strength polymer material that is not subject to corrosion and erosion, which ensures a long service life of the device.
• There is no need to constantly use bioactivators - the bacteria in the septic tank are restored on their own and actively multiply.
• Purification of toxic phosphates and nitrogen compounds is provided.
• Solid sludge is pumped out once a year or less.
• The Tver septic tank can be used even with intermittent operation - thanks to the combined cleaning method, the intermittent cycle does not create a large load on activated sludge and, in the absence of power supply, the septic tank goes into sleep mode.
• In a septic tank, liquid does not move through pipes or hoses, so there is no danger of clogging the system.
• The design calmly withstands salvo discharges of wastewater without loss of treatment quality.
• Large inspection hatches make it easy to carry out routine inspections of the system, maintenance and pumping of solid sludge.
• The compressor is located indoors - it is convenient for maintenance and significantly extends the life of the unit.
• Compact overall dimensions and light weight allow you to install the Tver septic tank on your own, without the involvement of special equipment.

Flaws:

• Energy dependence of the system;
• The high price of the complex.

However, the rather high cost of a septic tank pays off already during installation - there is no need to build absorption wells or spend money on arranging a filtration field.

Installation of the Tver treatment station is often performed on its own. This allows significant savings. The cost of such a design does not exceed the amount that would have to be spent on the purchase and installation of a treatment system based on a simple septic tank.

Model range of septic tank Tver

In order to choose a suitable treatment plant that will meet your needs, you need to familiarize yourself with the existing varieties of the Tver septic tank. The model range of the installation assumes the presence of 44 devices, which differ from each other in different capacities and volumes, which affect how many people can use this waste treatment station.

Various models suggest the presence of certain features characteristic only of them (each letter in the model name means a certain feature of the station):

Modifications of treatment facilities "Tver"

Executions of septic tanks Tver are classified depending on their performance - the amount of wastewater that the installation is able to process during the day. Choose the required volume of the tank, taking into account the number of people permanently residing in the house.

The performance of the modifications of Tver stations presented on the market starts from 0.35 cubic meters. m per day - this is suitable for 1-2 people. Next come the versions Tver-0.5P and Tver-0.75P - for 2-3 residents, Tver-0.85P - for 3-5 residents, Tver-1P - for 4-6 residents, etc.

The letter "P" in the designation means that the septic tank is made in a plastic case.

The maximum daily processing volume for a septic tank with a plastic body has a modification of Tver-3P. This design can serve up to 18 people.

Septic tanks with higher performance belong to the professional class, their body is made of steel. The productivity of such structures is from 4.5 to 500 cubic meters. m per day.

Models with pump compartments are available. The section with the pump may be the last one in the direction of liquid movement through the septic tank. Such modifications have the letter "H" at the end of the designation code - for example, Tver-1.5PN.

Pumping units are used to force the discharge of purified water to the relief or to the well, when the level of the discharge pipe is higher than that leaving the septic tank.

There are models with a pump compartment, which is located in front of the receiving chamber - the primary sump. The sewer pump pumps sewage into the septic chamber in the case when the main line leaving the house is located quite low underground - below 60 cm of the surface level.

Septic tanks with a pump are marked with the letter "H" at the beginning of the designation code - Tver-1NP.

There are also combined installations - their designation has the NPN code. For example, the performance of Tver-2NPN.

The option of using a septic tank with a pump compartment is optimal if the site has a very high level of groundwater. Digging a deep drainage ditch in this case does not make sense. Discharge of purified water occurs on the soil surface (+)

How to determine the water absorption of the soil

Before installing a new septic tank, it is advisable to find out how well the soil in the area absorbs water. The method of disposal of treated effluents largely depends on this. Experts recommend conducting a water absorption test, which is quite simple to perform on your own.

It will also help to determine the level of groundwater, which is very important in the arrangement of such structures.

To conduct the test, we sequentially perform the following steps. First, we drill a hole or dig a hole with a depth below the freezing level of the soil. On average, it is about 1.5 meters. Taking out a dump from the excavation, we try to determine the type: slurry, sand, etc. During digging, water may appear in the hole. This means that the first water-saturated layer from the daylight surface has been exposed.

Usually at such a depth, perched water is opened, which appears during a period of heavy rainfall and snowmelt. If it appeared at a depth above 1 m, then the container will need to be installed 15-20 cm above the recommended level.The bottom of the pit will need to be filled with a concrete screed and, without waiting for the mortar to harden, install mounting loops in the screed. They are needed to anchor the container - to secure it to the concrete slab with a cable, which will prevent it from floating up during the floods.

If clayey soil appeared at the bottom, the cleaned sewage mass will need to be diverted into the gutter. Loam and sandy loam does not allow water to pass through, so a fairly long pipeline will have to be arranged for discharge, and a pump will need to be purchased to stimulate the movement of fluid through it.

If the bottom and walls of your exploration working are composed of sands with thin layers of sandy loam and loam, you need to determine the filtration qualities of the soil. To do this, you need to pour water into the pit or well, fixing the volume of liquid and the time it took to absorb it.

It is possible that the liquid will not be absorbed completely, but will settle motionlessly at some level. This means that it will not go below or it will be absorbed too slowly. We carry out the pouring operation 5 or 6 times in order to obtain more objective data on water absorption. Each time we determine the volume of the filled liquid and the rate of its absorption.

It may turn out that there will be water at the bottom of the pit. If she does not leave even after a few hours, we can assume that it will be so forever. This means that under the layer of sand you uncovered, there is a clayey layer that will not let the liquid component of the effluents through.

Filtration properties must be taken into account when deciding on the method of disposal of treated effluents. For example, it makes no sense to equip a filtering well on clay rocks, because the liquid will not leave it.It cannot be built if the distance between the conditional bottom of the soil filter and the roof of the aquifer below is less than a meter.

For a device on a clay base, filtration fields are not suitable, which are a system of pipes with holes through which purified water seeps into the surrounding soil. They are laid in sandy soils that absorb well the liquid discharged from the system. By analogy with the device of the absorption well, there should be at least a meter between the bottom of the perforated pipes and the water-saturated reservoir.

The principle of operation of the septic tank Tver and its design

In Tver, wastewater treatment processes are most complete, this is achieved through the following processes:

• Heavier impurities settle to the bottom due to natural settling (impurities whose density is greater than that of water).
• Due to the occurrence in anaerobic processes, the structure of large formations in an airless environment is destroyed under the action of bacteria.
• With the help of aerobic processes of water under the action of microorganisms (optimum conditions for their vital activity are created due to the influx of oxygen from the air into the arotink), biological treatment of wastewater from organic inclusions is carried out.

Design and principle of operation

The design of the system is multi-chamber - it is divided by partitions into the following chambers:

• Septic (sump), it is also a receiving chamber for wastewater entering the sewer pipe from the house. In it, the process of settling to the bottom and subsequent settling of insoluble fractions takes place. Over time, heavy waste partially dissolves and moves on to the next stage of purification.

  

  

  

  

  

• anaerobic bioreactor.In it, mechanical destruction of wastewater occurs due to their passage through the structural elements of the container (ruffs), and partial waterproofing occurs due to the fermentation process under the influence of anaerobic microorganisms.
• Aerotank. Thanks to the aerator located in the chamber, the wastewater is saturated with oxygen, which makes it possible to accelerate the process of reproduction of aerobic microorganisms that are in the wastewater as a natural microflora. Further oxygen-saturated waters enter the further stage of processing.
• Sump. Before effluent enters the aerobic bioreactor, it passes through a settling tank, which retains heavy suspensions, and this has a positive effect on further decomposition of organic compounds.
• Aerobic bioreactor. Two processes take place here simultaneously: firstly, organic inclusions contained in wastewater are actively absorbed with the help of actively multiplying aerobic bacteria, and secondly, there is limestone at the bottom of the section, which, when dissolved in water, helps to neutralize very toxic nitrogen and phosphorus-containing compounds.
• Sedator calmer. In this chamber, additional clarification of the liquid occurs due to the natural sedimentation of heavier fractions to the bottom. Only upon completion of this process, 95-98% purified water leaves the Tver septic tank. In this chamber, floats containing chlorine reagents are additionally installed, which disinfect the water.

Disadvantages and features

Tver septic tanks have disadvantages inherent in all devices of this class:

1. Complete dependence on electricity. For the normal functioning of the septic tank, it is necessary that air is supplied to the aeration tank.Accordingly, in the absence of electricity, the compressor will not be able to carry out this process. But at the same time, Tver will operate for at least another day before its productivity begins to decline.
2. Relatively high price, but it must be taken into account that the sewerage system, where the septic tank is installed, does not need drainage fields and a drainage well, which significantly justifies the cost of Tver.

Let's move on to the features. The body of the structure has thin walls, but high-strength polypropylene is used for their manufacture. The case can bend, but it will not lose its tightness. On the other hand, thin walls make the structure lighter, so its delivery and installation are greatly simplified.

When transporting, dimensions play a decisive role, not weight.

Where to place the installation: rules and regulations

Septic tanks are among the potentially dangerous objects for the environment. Their installation requires permission from the SES. To get it, you need to draw up a project for the placement of equipment, which must take into account all applicable requirements and standards. If everything meets the standards, permission will be obtained. The project takes into account not only the location of the installation, but also its volumes.

The last indicator should not be less than the three-day maximum stock volume. The place where the septic tank is installed must be removed as far as possible from the well or from the well, if they are on the site. Although the treatment equipment is hermetically sealed, it is theoretically possible that an emergency situation could occur, as a result of which runoff could enter the aquifer.

To avoid such problems, the regulations regulate the distance from the treatment plant to the well or well for each type of soil. The minimum is 20 m. On average, if there is loamy, sandy or sandy soil on the site, this distance is from 50 to 80 m. There are certain standards that apply when laying water pipes. They must be placed at a distance of at least 10 m from the septic tank.

This completely eliminates the risk of water pollution in the event of a pipeline depressurization. Another nuance: when choosing a site for installing a septic tank, you need to remember that relative to the water source, the level of its location should be lower. In addition, it is necessary to take into account the norms regulating the distance between the treatment plant and the place of residence of people. From the foundation of the house to the septic tank must be at least 5 m.

However, too much distance between objects is highly undesirable, since a long sewer pipeline is more at risk of blockages.

It is important to choose the correct length of the structure. In the case of using a modification of the Tver septic tank with forced pumping of industrial water, it can be placed closer to the house. The ventilation riser in such cases is installed at the entrance to the external branch of the sewer and is attached to the wall of the house

The inlet sewer pipe can be about 1 m. The type of discharge and the length of the outgoing pipe depend on the geological and hydrogeological situation in a particular area. In any case, the external sewer network must be equipped with revision wells.

The ventilation riser in such cases is installed at the entrance to the external sewer branch and is attached to the wall of the house. The inlet sewer pipe can be about 1 m.The type of discharge and the length of the outgoing pipe depends on the geological and hydrogeological conditions in a particular area. In any case, the external sewer network must be equipped with revision wells.

It must be remembered that when choosing the location of the septic tank, the interests of not only the owner of the land plot, but also his neighbors should be taken into account. Therefore, the distance from the installation to the fence cannot be less than 2 m. If a road with sufficiently heavy traffic is laid nearby, the septic tank cannot be installed closer to it than 5 m. The distance from the foundation of outbuildings for any purpose to the septic tank should not be less than 1 m.

Professionals advise planning the installation of treatment equipment on a site with soft soil, which will greatly facilitate excavation. In addition, care must be taken to ensure free access to the device for its regular maintenance. All of the above requirements must be taken into account when choosing a place for a septic tank.

Disposal of excess activated sludge

With a sufficient amount of nutrients, the increase in the biomass of aerobic bacteria occurs very intensively. In this case, a lot of activated sludge is formed. Airlifts are installed in the secondary and tertiary clarifiers to dispose of its surplus.

An airlift is a jet pump that lifts fluid with compressed air. The design is very simple - it consists of two tubes and a compressor. One of the pipes carries pressurized air. It is brought to the bottom of the second pipe, lowered into the water.

An air-water emulsion is formed - a liquid filled with air bubbles. Its specific gravity is less than the specific gravity of the surrounding water pipe.Due to this, it rises through the pipe - denser water simply pushes out a lighter air-water mixture. Suspensions contained in water also become part of the emulsion and successfully rise.

Two airlifts installed in the Tver septic tank, together with the liquid, lift the excess activated sludge from the sections of the aeration tank and the tertiary sump. The mixture is pumped through the sludge pipeline to the septic chamber. The cycle closes.

The lineup

Tver septic tanks are of different volumes, for a different amount of drains. Each model has modifications that have a different letter designation:

• P - plastic case (without a letter, the case is metal).
• H - there is a pump compartment for forced pumping of treated water (a necessary option for high groundwater levels and a scheme with an intermediate well). If there are two letters H, then there are two pumps. The NPN marking indicates that there is a special compartment for installing the pump (in another case, it is suspended).
• M - increased insertion depth. As a standard, the inlet is located at a depth of 30 cm, in this modification it can be lowered to a level of 60 cm. In this modification, the position of the walls also changes, the height of the manholes of the manholes does not change.

The dimensions, volume and price of some models of Tver septic tanks are summarized in the table.

Preparation for the installation of a septic tank

Having decided on the method of discharging treated effluents, you need to equip a site for their reception: a drainage ditch, a filtration well or a field. Another important point: the preparation of the site for the entry of effluents into the septic tank. If the sewer outlet from the building is deep enough, it may be necessary to equip a pumping station. Contaminated liquid will flow into it by gravity.

The scheme shown in the figure with a sewer station is used only in the case of an excessively deep position of the sewer outlet from the building

Further, the fecal pump will pump it into the septic tank for cleaning. Pumping equipment is not needed if the sewer outlet is not too deep. In most cases, you will not need special equipment for the installation of a septic tank Tver. Its weight is small. The largest building with full "rigging" in the form of expanded clay, limestone, etc.weighs about 390 kg, which allows it to be lowered into the pit by several people.

Of course, it is more comfortable to work with special equipment, but if necessary, you can cope without it. The installation depth of the pit is small. For standard models, it is only 1.65 m, which greatly facilitates the work. That is why the Tver brand is willingly chosen for installation in areas with high GWL. You can dig a pit using special equipment or on your own.

Installation rules

Buying a septic tank Tver is not a problem, even if there are no specialized stores in the area of ​​​​residence, you can place an order through the website. But it is not enough to buy the installation, you need to put it into operation. Let's figure out how the Tver septic tank should be installed.

Installation work

To install a septic tank Tver, you will need to perform the following operations:

• carry out earthworks by preparing a pit and trenches for pipes;
• make a shock-absorbing cushion of sand, lay a reinforced concrete slab;
• install a septic tank, leveling the body;

• anchor by securing the hull with straps on the plate;
• connect communications - pipelines and power supply;
• the pit is filled with a specially prepared mixture of sand and cement;
• the first start of the installation.

Despite the fact that the installation of a Tver septic tank is not considered an overly complicated matter, the manufacturer does not recommend doing the work yourself. It is better to entrust the installation to specialists. The fact is that it is necessary not only to perform all operations correctly, but also to take into account local conditions - the type of soil, the topography of the site, etc.

How is your work going?
