The use of preammonization and primary chlorination in the process of the Moskva River water purification
Summary
The use of preammonization and primary chlorination for the purification of water from the Moskva River source is discussed. Two water purification process designs are suggested. The results of laboratory studies of temporal dynamics of chloroform formation and maximum efficiency of chloroform concentration reduction at various modes of preammonization and primary chlorination are presented. Comparative evaluation of chloroform formation intensity in the process of water purification with the use of preammonization and primary chlorination versus traditional water treatment process is given. A reliable operational benefit was obtained that provided for meeting the standard for permissible amount of chloroform in drinking water as well as the basic chemical and microbiologic parameters of the required water quality.
