Ecologizing of Treatment Methods of Natural Waters Containing Dissolved Organic Substances

Abstract

Taking into consideration the operating experience of water treatment facilities, we have made an analysis of hazardous consequences of preliminary chlorination for decoloring of natural waters, we have also examined the mechanisms of application of chlorine-containing substances to organic impurities, which are present in an untreated water. It has been determined that there is a necessity of preliminary water treatment before prechlorination as this procedure ensures the required destruction of complex organic compounds. Moreover, we have explained and justified the principles of preliminary treatment of natural waters in biologically active environment, which will allow eradicating the formation of toxic substances and pathogenic microorganisms.
