Bacteria for septic tank

The principle of operation of the septic tank, which is part of the autonomous sewage system, is based on biological treatment of sewage and fecal waters using specially grown living microorganisms. Their use today is the most affordable and effective for use in everyday life. Bacteria for the septic tank - this is the main element of any self-contained treatment plant.

Special biopreparations for septic tanks, consisting of a mixture of bacteria, completely decompose, do not contain toxic substances and do not damage the environment. Microorganisms break down the organics into water, salts and carbon dioxide. Bacteria for septic tanks quickly process waste waste and eliminate an unpleasant odor.

As a result of the life of microorganisms, the sediment on the bottom of the tank is liquefied, the process of decomposition of organic waste is accelerated, the deposits of fat from the walls are removed, and blockages are eliminated. Bacteria begin to process the organic matter within two hours after entering the sewage. Especially quickly they affect the process of gas formation, reducing the unpleasant smell after four hours. In this case, bacteria for a septic tank are not dangerous for humans, animals and higher plants. They do not damage the materials from which the treatment facilities are made.

In septic tanks, different types of living microorganisms are used, depending on the type of septic tank. These are aerobic and anaerobic bacteria.

Aerobic bacteria

Aerobic bacteria are microorganisms that require oxygen for their existence. The treatment facilities, whose operation is based on the vital activity of such microorganisms, are aerobic and equipped with a compressor supplying air to the reservoir. To ensure that the bacteria for the septic tank are not washed away with water, they are placed on a special shield made of a textile material with villi. Sewage entering the septic tank is mixed with air bubbles. In the septic the decomposition of organic compounds begins, as a result of which a solid sediment precipitates onto the bottom of the tank, which can be used as a fertilizer for the garden. During the decomposition of organic substances with the help of aerobic microorganisms, carbon dioxide and heat are released, but there is no unpleasant odor. After aerobic treatment, the wastewater is immediately discharged into the drainage ditch. Aerobic septic tank does not require a sewage machine call.

Anaerobic bacteria

For the life of anaerobic microorganisms, oxygen is not required. In the anaerobic treatment plants there is a process of natural fermentation and rotting of organic waste, some of which settle to the bottom, where it begins to decompose. At the same time, sewage is clarified and clarified.

Anaerobic bacteria for a septic tank can not clean domestic sewage from non-degradable organic matter and fats. Dilution of solid waste can be achieved by the right combination of microorganisms. During the anaerobic purification process, an unpleasant odor is generated. Sediment from the bottom can not be used as a fertilizer, because it contains pathogens. To remove it, you need to call a sewage transport.

Before draining the anaerobically cleaned wastewater, they must be cleaned aerobically. Drain untreated water in the soil is not recommended, since the soil after this becomes infertile. Thus, for the treatment of sewage, septic tanks are used, including two tanks, anaerobic and aerobic. The wastewater subjected to such a process is purified by 96-98%.Instead of aerobic septic, sand-gravel filtration fields can be used, where purification takes place due to the vital activity of soil bacteria.
