The first compartment is the largest and plays the role of a sediment bowl. All wastewater coming from a house is first collected here.

Stocks gradually accumulate and settle. The solid component of the effluent, as well as the content that cannot be recycled by microorganisms, accumulates below.

A fatty film is formed on the surface of those wastes that are lighter than water. In the process of accumulation of primary wastewater, the volume of the settling tank increases, and the liquid level rises. Over time, it reaches the overflow hole, through which the partially cleaned during settling liquid enters the second septic tank.

Septic system

The diagram shows the device of the “Flotenk” septic tank, consisting of three chambers of different size. The first is the upholding of wastewater, and in the other two - their active cleaning (+)

Here, microorganisms continue to work on wastewater treatment, already freed from solid fractions. As the volume of waste in the second section of the septic tank increases, the fluid level rises again and reaches the overflow opening leading to the third section.

Here, the wastewater is finally clarified to a degree that is considered acceptable for moving the produced liquid to the surrounding soil. To remove liquid treated wastewater from a septic tank, it is necessary to create a special filtration field in the thickness of the ground.

The principle of operation of the septic tank

This scheme allows you to get an idea about the principles of operation of the “Flotenk” brand septic tank. The effluent from the utility rooms enters the device, undergoes biological treatment and is displayed on the filtration field (+)

To do this, at a distance from the septic tank make a number of trenches or a pit, at the bottom of which arrange a sand and gravel filter. It includes layers of sand, rubble and gravel. The trench is laid first layer of filtering gravel-sand backfill, over which have a system of perforated pipes - drains.

Drainage sewer system is wrapped with geotextile and fall asleep. Each branch of the filtration field is equipped with its own ventilation riser to remove the methane produced during the treatment.

After-treatment using such a filter will make the effluent completely safe for the environment. Moreover, the microorganisms contained in the soil aeration zone also continue the process of processing residues of substances that enter with the wastewater.

Filtration field for septic tank Flotenk

Filtration field for soil purification can be arranged only in permeable soils: sand, gava, pebble, rubble sediments - in rocks that can absorb and pass recycled wastewater. In addition, between the groundwater level at the construction site and the bottom of the drainage system must be at least one meter.

At the top, each department of the “Flotenk” septic tank has an operational opening that provides constant access to the device. This provides the conditions for successful livelihood of aerobic bacteria, and also allows you to remove gases from the tank, obtained during biological processing of wastewater.

Of course, solid waste will gradually accumulate in the sump. A significant part of them will turn into neutral sludge. The more waste, the smaller the capacity of the septic tank, i.e. its performance. The first compartment of the septic tank should be periodically cleaned with ilososa.

Advantages and disadvantages

The simple design and principle of operation guarantee the almost complete absence of breakages during the operation of the “Flotenk” septic tank. The case of the device has no seams, which provides increased resistance to the effects of both internal and external pressure.

Septic tank

Septic tanks “Flotenk” are made of modern polymeric materials using a seamless technology that provides the device with a high degree of resistance to stress.

Inside the surface of the septic tank is made as smooth as possible. The lack of roughness makes the septic tank dirt-repellent, which allows less effort to clean up it when removing oozy deposits and not recycled waste.

The overflow pipes inside the septic tank are also of high quality. They are equipped with reliable rubber gaskets, providing excellent tightness. The contents of the various sections of the septic tank does not mix, which increases the efficiency of biological wastewater treatment.

Septic tank

After installation, both the Flotenk septic tank and the filtration field for it are located underground, they will remain on the surface only three operational hatches and ventilation pipes that will not adversely affect the state of the surrounding landscape

One of the main advantages of “Flotenka”, which cannot be boasted of higher-grade VOC, is its non-volatility. Even a complete power outage in the house does not affect the work of the septic tank, since none of its nodes need power supply. As a result, the cost of maintaining it requires minimal.

Simple installation is another significant advantage of the Flotenk septic tanks. All work on the installation and connection of the septic tank can be done independently or with the help of a couple of good friends. Minimal construction skills and precise instructions will reliably protect against errors.

The disadvantage of the “Flotenk” septic tank is the low physical weight of the device. This is convenient during transportation and installation of the device, but not during its operation. Under the influence of groundwater during the spring flood or during the freezing of the soil in winter, a light construction that is not filled with drains can simply be pushed to the surface.

It is relatively easy to fix this problem. To do this, when installing a septic tank at the bottom of the pit, a solid concrete base is arranged. Septic tank is installed on this base and attached to it with a reliable cable.

Septic transport

Due to the low physical weight, it is easy to transport the “Flotenk” septic tank, but during installation it should be fixed on a concrete base to prevent ascent

Another problem is the quality of wastewater treatment. Local treatment plants, which process wastewater, allow decomposing into water and neutral sludge with a degree of purification of 96-98%. The resulting water can be used for technical needs, for example, for watering plants on the site.

Silty accumulations in such VOCs serve as a useful fertilizer. But simple in design and principle of operation “Flotenk” cannot provide such a high level of purification. Therefore, during its installation, it will be necessary to create and attach another structure to the septic tank - an absorption well or a filtration field to which water will be drained for final cleaning.

How to install a septic tank brand Flotenk

The installation of a septic tank, characterized by the lightness of the body, is made using an anchoring system. To do this, when casting a concrete slab, loops are laid in it, to which then a septic tank will be attached with straps

How to choose a suitable model?

The range of septic tanks “Flotenk” is quite extensive, which allows you to choose a device suitable for serving a particular house, family or even a group of houses. Septic tanks are marked with the letters STA, next to which are the numbers.

The larger the figure, the higher the volume and performance of the septic tank:

  • Flotenk STA 1.5 processes 500 liters of wastewater per day;
  • Flotenk STA 2 processes 700 liters of wastewater per day;
  • Flotenk STA 3 processes 1000 liters of wastewater per day;
  • Flotenk STA 4 processes 1300 liters of wastewater per day;
  • Flotenk STA 5 processes 1700 liters of wastewater per day;
  • Flotenk STA 6 processes 2000 liters of wastewater per day;
  • Flotenk STA 10 processes 3,300 liters of wastewater per day.

In addition to the performance of individual models of septic tanks "Flotenk" vary in size, volume and, of course, in price.

The cost of the device increases depending on its performance. The numbers start at about 30 thousand. rubles for the Flotenk STA 1.5 model, and for the Flotenk STA 5 model it is already necessary to pay 90 thousand. rubles.

Septic tank range

Septic tanks “Flotenk” are distinguished by a rather wide model range, which allows you to choose the right device for almost any home, even for a small hotel.

Of course, these figures may vary depending on the region, the ratio of supply and demand, as well as other factors. The specific price is better to find out directly from the supplier.

When choosing a suitable model of the “Flotenk” septic tank, it is necessary to take into account its volume and dimensions, which can be:

  • 1500 l, 2100 mm in length and 1000 mm in diameter for the model Flotenk STA 1,5;
  • 2000 l, 2700 mm in length and 1000 mm in diameter for the model Flotenk STA 2;
  • 3000 l, 2900 mm in length and 1200 mm in diameter for the model Flotenk STA 3;
  • 3000 l, 3900 mm in length and 1000 mm in diameter for the model Flotenk STA 3;
  • 4000 liters, 3800 mm in length and 1200 mm in diameter for the model Flotenk STA 4;
  • 5000 liters, 2700 mm in length and 1600 mm in diameter for the model Flotenk STA 5;
  • 6000 l, 3200 mm in length and 1600 mm in diameter for the model Flotenk STA 6;
  • 10,000 liters, 5,200 mm in length and 1,600 mm in diameter for the Flotenk STA 10 model.

It should be noted that the model Flotenk STA 3 comes in two dimensional versions with the same volume and performance. The buyer can choose a model that is slightly shorter and larger in diameter or a longer and narrower device. The length and diameter of the tank affect the size and configuration of the pit, which will be needed to install a septic tank.

The most expensive and productive model of a septic tank from the brand Flotenk STA 10 is so roomy that it can be used to service several houses or even a small cottage village. Such a device is also suitable for a large cottage with a large number of residents, for example, for servicing a private hotel or a mini-hotel.

Septic parameters

This table allows you to study the basic parameters of the “Flotenk” septic tanks in order to select the appropriate device according to the needs of a particular house

Septic tanks "Flotenk" selected depending on the number of people who constantly live in the house. It is believed that for a small summer cottage or a family of three people the ideal choice would be the minimum performance option - Flotenk STA 1.5.

For four to five people fit model Flotenk STA 2. A family of six people is recommended to use Flotenk STA 3, and the Flotenk STA 4 model is more suitable for a house where eight tenants reside. Modification of Flotenk STA 5 is designed for use in the house in which ten people live. But Flotenk STA 10 can serve the building with 17 permanent residents.

Choosing the right model, you can use simple calculations. It is necessary to multiply the estimated number of residents by 600 liters and focus on the resulting volume. It does not make sense to take a large-scale septic system as if “in reserve”, unless a sharp increase in the number of tenants in the house is planned in the near future.

Benefits of a septic tank

Septic "Flotenk" is a simple and reliable device that allows private households to be efficient and very easy to maintain autonomous sewage

The larger the septic tank, the higher the cost of its installation, and the more difficult its maintenance. If it later turns out that the tank is slightly “too small”, you will simply have to order the ilosos to clean it a little more often. Considering that usually the septic tank “Flotenk” needs to be cleaned about once a year and a half or three years, this time will not cause major problems.

Sometimes it is decided to put on the site not one, but two small septic tanks, for example, for the house and separately for the bath. Such a decision may have a positive impact on the quality of biological wastewater treatment, but will require additional costs. The purchase of two septic tanks of 1.5 cubic meters each. m will cost about one and a half times more expensive than buying a single device with a volume of 3 cubic meters.

The most popular is exactly the model Flotenk STA 3, which holds 3000 liters of waste. It is optimal in terms of volume and price. Its cost is four times lower than the high-performance version of Flotenk STA 10.

Features of the installation of septic tanks “Flotenk”

As noted earlier, the installation of the “Flotenk” septic tank is relatively uncomplicated.

And yet, to properly install the device, you will have to do a lot of operations:

  1. Dig a trench for the sewer pipe leading to the septic tank from the house.
  2. Dig a pit under the septic tank.
  3. Concreting the bottom.
  4. Lower the container into the pit and attach it to the base.
  5. To carry out work on the insulation of a septic tank.
  6. To connect a septic tank to the house sewerage.
  7. Dig trenches for the filtration field.
  8. Lay in a trench sand and gravel filter.
  9. Backfill the pit.

At each stage of the installation of the Flotenk septic tank, it is necessary to adhere to certain standards and requirements. So, in the middle lane a trench for a sewer pipe leading to a septic tank from a house is recommended to be made about one meter wide and about one and a half meters deep. This will allow laying the pipe below the ground freezing level.

Septic installation

This scheme allows you to get an idea of ​​how to choose a suitable place for the installation of the “Flotenk” septic tank in compliance with safety requirements (+)

As an additional protection in case of frost, it is recommended to warm the outside part of the sewers. The trench should have a slight slope so that the drains move to the septic tank in a natural way. After the pipe is laid, it may be necessary to drill the foundation of the house to connect the outside and inside of the sewer system.

The diameter of the hole must comply with the parameters of the sewer pipe. The standard size of such communications is usually 160 or 110 mm. Now you can start digging a pit to install a septic tank. Its overall dimensions and configuration are determined by the parameters of the septic tank.

Step 1: Pit to install a septic tank

To install a septic tank, we develop a pit, focusing on the dimensions of a particular model. Between the walls of the excavation and the septic tank should be at least 0.5 m

Step 2: Laying the reinforcement to the bottom of the pit

In order to determine the required depth of the pit, it is better to bring a sewer pipe to it in advance. At the bottom of it fit fittings for pouring concrete base

Step 3: Pouring the base concrete slab

In two steps we pour the slab, first to the level of the reinforcing mesh, then an hour later to the laid 10 cm thickness of the slab. Install embedded parts - metal hinges for anchoring capacity

Step 4: Dip the septic tank into the pit

We immerse the container in the pit, check its horizontal position, produce anchoring: fasten it with a cable to the hinges. Then sprinkle the bottom with sand.

Step 5: Connect the sewer pipe

We connect to the septic tank sewer pipe coming from the house, then on the other hand - leading out drains to the ground treatment system

Step 6: Mounting the ventilation pipes

Fix the ventilation pipes located above the chambers of the septic tank, be sure to use a seal in the joints

Step 7: Fill Tanks with Water Before Filling

Before filling the reservoir pit, fill it with water to prevent the structure from deforming due to soil pressure.

Step 8: Flotenk septic tank in the area

Fill the pit with river or quarry sand in layers: we fall asleep 30 cm - gently ramming in order not to damage the body - we fall asleep again

Step 8: Flotenk septic tank in the area

Step 8: Flotenk septic tank in the area

To the length and diameter of the tank should be added 600-1000 mm. For example, for the Flotenk STA 1.5 model, you will need a ditch with a length of 2700-3100 mm (2100 mm + 600/1000 mm) and a width of 1600-2000 mm (1000 mm + 600/1000 mm) and a depth of 1400 mm (1000 mm + 400 mm ).

The depth of immersion of a septic tank is calculated as its height (i.e. diameter of the tank) plus another 300-400 mm. In our example with the Flotenk STA 1.5 model, the depth of the pit will be 1300-1400 mm (1000 mm + 300/400 mm).

The pit in which the septic tank will be installed should provide a place for the concrete base under its capacity and allow connection to the sewage system at the correct height.

Once the pit is ready, you can take care of creating a filtration field. It is a series of parallel trenches, with a filter and perforated pipes laid inside. Purified water from the septic tank will flow through the pipes and gradually seep into the soil through the filter.

Septic tank filtration field

To create the filtration field of the “Flotenk” septic tank, you will need to make a series of trenches or one common pit. Perforated pipes are placed on a layer of gravel or rubble.

Usually they make not one, but several such trenches. Their length should be sufficient to ensure that the septic tank is relieved of fluid in a timely manner, which will prevent its overflow. Calculate the length of the trenches of the filtration field as follows: the number of occupants in the house is multiplied by 8-10 m.

So, for a family of three you will need a filtration field with a length of 24-30 m. The further these pipes go from home, the better. At the bottom of the trench, you need to put a filter consisting of layers of sand, gravel and / or rubble. Sometimes, instead of sand, agrofibre is used, on which rubble is poured and leveled, the layer thickness should be about 400 mm.

System of infiltrators for purification

To facilitate and accelerate the construction of the filtration field, the company produces and offers for sale infiltrators

Option to install a filtration system

Depending on the configuration of the site and free space on it, infiltrators are installed in series in one trench or in parallel

Complex filter trenches

Excellent purification of waste water two-tier system of filter trenches. The drains in it are stacked one above the other: from the upper water flows into the ground for additional treatment, the lower one collects it and leads it to the disposal site

Filter sewer well

If there is little free space on the site, and the groundwater is located at a depth of more than 5m, absorption wells are constructed. In the usual sense, there is no bottom of the well; instead, a soil filter with a capacity of more than 1 m is filled in

In the trench lay plastic sewer pipes, the length of which is perforated. Now the bottom of the pit for the septic tank should be concreted. First, the bottom is laid down, tamped and leveled sand pad 200 mm thick.

From above mount the reinforcing lattice with a cell of 200 mm. Parts of the reinforcement near the edges of the pit are made longer and give them a loop-like shape.

In the future, these loops will become places of fastening of the septic tank to the base. After that, the base is poured cement-sand mixture. It is possible to continue installation of a septic tank only after the basis reliably stiffens. Do not rush to not violate the integrity of the fill.

Instructions and installation rules for the Flotenk septic tank

It should be borne in mind that it is better to have a septic tank on the side of the natural slope of the site at a distance of 3 to 5 meters from the foundation of the house. It is necessary to provide the possibility of the approach of the truck of the vacuum trucks to periodically empty the tanks (+)

Now the capacity of the septic tank is lowered into the pit and attached to the loops of the base with pieces of steel cable. Before starting to backfill the pit with soil, it is necessary to fill the septic tank with water. If this is not done, the mass of the soil during backfilling can simply crush the walls of the device.

First, the soil is poured to the level at which sewage and filtration pipes are attached to the septic tank. Then connect these pipes. Over each compartment septic tank there is a channel for maintenance. They should wear special sockets.

Step 1: Sewing station selection

The station, which produces deep sewage treatment, is selected according to its capacity. To facilitate the selection of the manufacturer indicates the number of people living in the house, equipped with autonomous sewage

Step 2: Forming a pit for station installation

To install a sewage treatment plant in the ground, we develop a pit. Faster and easier to carry out these works excavator

Step 3: Immersing the hull in a prepared pit

Using an excavator bucket as a forklift boom, install the sewage station in the pit

Step 4: Leveling the cleaning station case by level

Align the sewer station building according to the indications of the construction level. Housing must be horizontally mounted

Step 5: Pipeline Installation

We approach the station and connect the pipe that runs from the house to the building, on the other hand, we connect the pipe that discharges purified water to the disposal site

Step 6: Filling the pit with quarry sand

We pump water into the station in order to start the recycling process and protect the case from deformation during backfilling. Fall asleep pit

Step 7: Arrangement of the hole to enter the house

To enter the sewer pipe into the house with a diamond drill we drill a hole in which we install the sleeve, fill the gaps with foam

Step 8: Area around the station

The pit is poured so that the neck of the station with the hatch rises above the surface of the surface by 15 - 20 cm
