During the construction of water treatment stations in group water pipelines, it exceeds 15 ... 30% of the cost of the entire system and directly depends on the technological scheme, the choice of which, in turn, is influenced by the quality of the water in the source and the performance of the station. In large group water supply systems, water from surface sources is usually used, which must be clarified, discolored, deodorized, and disinfected.

There were considered the processes of electrochemical coagulation and contact filtration for clarification, bleaching and disinfection of the Don River. There were made the experiments to compare electrochemical coagulation to chemical treatment of water with different reagents in conditions of contact filtration. There were defined feculence change, water chromaticity depending on reagent dose and the changе of the total microbial number.
