The article analyses chemical methods to treat washwater from rapid filters at surface water treatment plants. The review of existing approaches to the application of rapid filter washwater is carried out. During the research work washwater from rapid filters was chemically treated with coagulant “Bopak-E”, flocculants “Praestol”, and sorbent-coprecipitant reagent “Ecosol-401”. The doses of reagents were selected and the efficiency of water purification from turbidity and chromaticity was shown. The proposed technology of washwater treatment allows to obtain drinking quality water after sedimentation and filtering.
