During mechanical wastewater treatment advocated and insoluble impurities are caught by a variety of devices.Chemical treatment involves the use of chemicals that remove contaminants in the insoluble pellet.This method is rather expensive purification, and therefore is typically used in the industry.

in the household these days are increasingly using biological treatment, at which the processing of waste water using aerobic bacteria, emerging when entering sewage and oxygen supply.Biological treatment - is accelerated by aeration natural process.This method of wastewater treatment is the basis of the work of autonomous sewerage "TOPAS" and "TOPAERO" produced by "Topol-ECO."


Biological treatment is based on the fact that domestic waste waters are a mixed bag.They contain a large number of organic substances, fats, fecal matter, surfactants (shampoo, soap).Highly diluted with water organics is a breeding ground for microorganisms, which are almost completely absorbed or decomposed into

its components.Because of this waste water are released from the odor, become transparent, not rot.As a result of the treatment plant produced purified water and silt of the second category (sapropel).

Wastewater treatment takes place in several stages.Used water for sewer pipes gets into the wastewater treatment unit.The receiving chamber drains are the primary biological and mechanical cleaning.After that half-purified water is pumped into the aeration tank, airlift, which is oxidized using activated sludge.As a result, organic compounds are destroyed, and the water is completely cleared.

The next phase mixture of water and sludge is moved to the secondary clarifier, which is in the form of an inverted pyramid top down.There sludge sinks to the bottom, and the purified water leaves the treatment plant.Device WWTP provides multiple use of activated sludge.Only after participation in several cycles decomposition of organic residues (up to 10 cycles per day) yl accumulates in the regulator and is pumped via airlift pump.

formed during the deep biological treatment sludge is used as fertilizer for ornamental plants, after having kept it in the compost a couple of weeks.The degree of purification of waste water installations "TOPAS" and "TOPAERO" is not less than 98%, which fully complies with sanitary and environmental standards applicable in the territory of the Russian Federation.This high degree of purification allows discharging purified water in a drainage ditch or a well used for watering lawns, washing cars.
