Methods for cleaning sewage sinks
Before buying a bio station or making a septic tank at your dacha, it would be nice to understand the operation of such devices in the most general terms.
- Mechanical .Sedimentation, removal of large suspended impurities, filtration;It is used most often in industrial sewer systems, where waste water is cleaned up to 65-70%, but also works fine in household septic tanks.
- Physico-chemical .Soft transition from simple mechanical filtration of sewage to chemical decomposition of impurities present in them. Dispersion suspensions and organic matter are removed, and the chemical reagents working in such sewage schemes are absolutely harmless to humans. Coagulation, extraction, oxidation and other chemical processes that will occur in such septic tanks in your personal farm will hardly interest you.

Biological cleaning .All the best in our life comes from industrial giants. Clean up the drains of oil, cellulose and other actively operating industrial enterprises have learned a long time( Rosprirodnadzor suggested), and small household devices with a similar principle of action appeared on the market very recently.
Deep biological treatment stations: pluses of
It is necessary to begin the arrangement of such a serious engineering network in a private sector with a detailed economic calculation. Build at the house on 6 ares, where 3-4 people live in the summer, aeration tank for 10 cubes is the top of waste. It should be remembered that aerobic bacteria that will provide biological treatment of the sewerage of the country house are very capricious: they live, reproduce and work at temperatures of +20-40 degrees.
How do these microorganisms ensure the cleaning of sewage sludge? Elementary: they recycle all your waste into silty sediments, in which, strictly speaking, they live. Oxidation of chlorides, sulfates, phosphates, inevitably present in sewage, is served by an inconspicuous microflora of biological purification. The advantages are obvious:
- installation of a compact ready-made sewage treatment unit can be done even with your own hands, if they were stuck in the right place as a child;
- The efficiency of such aeration appliances is 95% for manufacturers' assurances, but for country conditions with vast aeration fields and 70% is enough;
- maintenance of this septic tank is seasonal in nature: remove silted growths, clean the supply pipes of sewage streams, and private biocanalization again as new;
- installation place can be chosen arbitrarily;modern compacts of biological purification are designed for a temperature range from -30 to +40 degrees and almost any pressure of the underlying soils.
Aeration biocanalization for a private house
Special problems with such a system in the case of professional installation and even with the biocanalization device by their own hands will not arise only under three conditions:
- to choose the equipment of such a plan should be with some margin;the family is growing, the water is flowing, and no one wants
- to rebuild the whole system of tapping and cleaning of sewerage septic tanks, that such a purification facility on your site exists;The regularity of checking biotenes can be estimated by yourself, but once a month you open the lid;
- get confused in membranes, compressors, aerators and other parts of the complex - call specialists.
Biological wastewater treatment is not a panacea for all sewer problems, but it allows you to hide them deep underground. True, it will not be worth it: the autonomous sewerage TOPAS from Ekodin will cost 5,000 people for a holiday cottage for 69,000 rubles, for a guest country estate - 130,000.But the ecology is worth it.
