How to install a BioDeca septic tank

You can install a septic tank on the site yourself or hire specialists. Special equipment is not required.

Install an autonomous sewer in the following order:

Installation instructions

choose the place where the cleaning structure will be installed;
carry out earthworks with the construction of a foundation pit for the station;
perform a sand cushion (base);
the structure is installed in the pit;
the tank is filled with liquid and filled up;
septic tank is on.

When installing the structure, care should be taken to insulate the sewer pipe, which will connect the internal sewer system to the septic tank. Otherwise, you can create big problems for yourself when the pipe freezes in the winter.

The guaranteed service life of the plant is 50 years. During this time, the owner of the site will not have any questions about the removal of sewage from the housing.

Instructions for use and care of BioDecom

The sewerage system operates offline. The operation of the septic tank is monitored at least once a month. Installation material allows to place it in any kind of soil. The property of the body to prevent the penetration of moisture and withstand low temperatures, makes it possible to install a septic tank in any type of soil and places with an elevated level of groundwater. Additionally, drainage or storm sewers are provided to remove moisture from the installation.

All residents of the house must know and follow the basic rules for using the unit:

Reviews about BioDeca

it is forbidden to throw into the sewer system means and material that does not decompose over time. It can be rags, solid insoluble objects;
it is not recommended to get into the septic tank substances that can destroy the beneficial bacteria of activated sludge. Such substances are petroleum products, chlorine, acids and alkalis.

At certain intervals, the chambers of the station should be freed from the resulting activated sludge. You can hire specialists in vacuum trucks with special equipment, but these works are easy to do by yourself by connecting a fecal pump. Thereby providing the site with high-quality fertilizer.

The main activities for the maintenance of the sewerage system:

monthly visual external inspection of the installation for damage;
regularly check the outlet drains for the presence of odor and foreign matter;
control the presence of activated sludge, constantly pump it out at least once a year as it is added;
maintenance of filtering equipment, airlifts should be performed once every 6 months;
if significant violations are found, contact a specialized organization for qualified assistance.

A short overview of popular models

According to the purpose and principle of operation, all septic tanks are the same, they differ in performance, dimensions and depth of sewage inlet.

BioDeca -3 S-600

This minimum capacity system assumes the presence of up to 3 people in the house. The indicators of household waste and sewerage (bathroom) are taken into account.The system will work effectively with the simultaneous use of sewerage by all three family members.

The dimensions of the installation are small - up to 2 meters high, which allows you to freely dig it into the ground. The entrance of sewer pipes to the structure is at a depth of 0.6 meters, therefore, in order to install the system in regions where cold weather prevails, additional insulation of the sewer pipe in the ground is necessary.

BioDeca -5 P-1300

The system is designed for residential buildings with 5 people. The size of the station in height significantly exceeds the size of the previous instance. The installation has excellent performance. The depth to which the sewer pipe must be laid is 1.2 meters. The biological treatment system is suitable for most regions where the depth of soil freezing is small. Communications do not require additional insulation.

The letter C or P indicates the presence of gravity or the possibility of connecting a forced sewage disposal during the installation of the station. Models with forced drainage are placed in places with a close location of groundwater. The price of the system will be an order of magnitude higher than the sample for 3 people.

BioDeca -8 P-1800

The cleaning system has a high productivity, designed for the simultaneous use of sewerage by 8 residents. The installation proved to be excellent when working on two residential buildings at once. The biological treatment system has large dimensions with a sewer pipe entry depth of 1.8 meters, which makes it difficult to carry out earthworks. Widely used in northern regions with cold climates. The system is expensive.

There are units designed to serve up to 20 people. They are suitable for sewerage and household drains of public buildings, cafeterias, gas stations, private hotels.

BioDeca septic device

Appearance of a septic tank

To find out the principle of operation of the BioDeca septic tank, you should familiarize yourself with the device of this design. The body material is high-strength plastic, which allows the system to be operated in any climatic conditions. The body has a cylindrical shape with one welded seam, which increases the reliability and strength of the structure.

The device inside is equipped with a system of cameras, which are separated by partitions. Cameras sequentially perform certain functions. The system is compact and virtually maintenance free. There is no need to lay a special access road to the station. The pumped-out sludge is widely used as fertilizer for plants.

The main components of the BioDeca autonomous sewage system:

The interior of a septic tank

primary sump;
aerotank chamber;
stabilizing department;
denitrification zone;
secondary sump;
aerator and airlift.

The autonomous sewage system is equipped with an emergency alert.

How a septic tank works

The operation of the BioDeca station is based on the use of aerobic bacteria that perform biological wastewater treatment. The process of cleaning the sewage system is carried out in stages:

primary settling - first of all, insoluble and heavy particles are separated;
biological wastewater treatment;
repeated sedimentation, as a result of which activated sludge settles to the bottom of the chamber.

The technological process of the BioDeca installation

mechanical cleaning

Each passage of wastewater through the chamber system is accompanied by a certain process. Waste water, entering the first sump, with the help of aerotanks installed in it, is broken down by the size of the waste. When filling the chamber above a predetermined level, drains are automatically pumped by airlifts to the next compartment.

The cleaning technology incorporated in the design of the Biodeca is by far the most effective and has many advantages.

Biological treatment

At this stage, aerobic bacteria are connected and direct purification of the liquid occurs. Effluent is clarified, and activated sludge is formed from the sediment. Beneficial microorganisms live and multiply only in an oxygen-enriched liquid environment, so the process of supplying air to the system must be continuous. If it is disturbed for any reason, microorganisms begin to die after a few hours, and the quality of the water at the outlet will gradually deteriorate.

The principle of operation of the biological treatment plant

Activated sludge is pumped into the stabilizing compartment, where it is blown. Clarified effluents from the aerotank chamber are sent to the denitrification zone, where wastewater and prepared activated sludge are mixed.

Oxygen does not participate in this reaction. As a result of mixing, a biological film appears, which is removed using a pump.

This is followed by the final stage of biological wastewater treatment. Water enters the second settling tank, where the sludge is pumped out.
