In view of the development of cottage construction and enterprises of agricultural products processing, located mainly in rural areas, the development of high-efficient, reliable and easy-to-use treatment plants for the purification of domestic wastewater of low quality is very relevant.

The objective of the research is to ensure the high quality purified water and minimize capital and operating costs.

To solve this problem, the methods of physical and mathematical modeling were used, as well as numerical and analytical methods for determination and analysis of the parameters of treatment facilities operation.

To use the latest advances in science and technology in the area of small-scale wastewater treatment facilities, which are typical for rural settlements and agro-industrial enterprises, in these conditions it is proposed to use bioreactors and contact clarifying filters.

As the research has shown, water quality indicators of purified water change during the time of water filtration Tf and depend on the velocity of water filtration Vf and a specific cleanings capacity of the filter: at the beginning their values decrease as a result of accumulation of active sludge in the subfilter space, and then they begin to rise due to the increase of hydraulic resistance to water motion and removing this residual matter into filtered water.

The article also presents the results of investigations on changes in the content of organic compounds in filtered water during the filtration cycle Тf by the biochemical oxygen consumption value (BOCV) depending on a water filtration rate Vf, m/h, and the amount of active sludge (specific dirt content of the filter G, kg/m2), as well as the changes in the content of suspended matter Сf.i. due to the same parameters.

The recommendations on the effective operation of wastewater treatment facilities of the proposed design that which ensure their reliable and high-performance operation, were developed.
