Purification of backwash water from water treatment plant filters using combined coagulants

Abstract. The article discusses the treatment of backwash water from drinking water treatment facilities from open water supply sources at water treatment plants in the cities of Krasnoyarsk and Novosibirsk. The article presents the results of experimental studies of the efficiency of the technology for cleaning wash water by settling and filtering in clarifier reactors using a number of well-known modern reagents, varying their initial concentrations in various proportions and searching for the most effective ratios to improve the efficiency of water purification using the synergism effect.

Keywords: water treatment, filter, wastewater, coagulant, coagulant composition, experiment, purification efficiency
