The purpose of a technological research is the development of a technology that would allow eliminating the discharge of untreated washing water from a water station in Omsk into the Irtysh, with their repeated use. The paper presents the results of a technological research, which made it possible to determine the optimal technology option for reuse of wash water filters. The studies were carried out by the trial coagulation method, introducing a different amount of contaminated wash water from 10 to 30% into the initial river water and the reagents used in the waterworks. When the combined purification of river and untreated washing water, the turbidity in the settling process decreases to 4.35 mg / l. The efficiency of purification increases with an increase in the amount of raw washing water also increases up to 30%. The technological solutions adopted on the basis of the conducted studies formed the basis for the design documentation for the facilities aimed at developing the re-use of wash water from the Omsk waterworks. The facilities have been built and are being successfully operated now. The proposed solutions made it possible to reduce the intake of water from the source by 10-16.5% and to eliminate the discharge of the contaminated wastewater from the station into the river of Irtysh up to a volume of 51 thousand m3/day.
