Preconditions for Transition to the Use of Ammonium Sulphate for Disinfection of Potable Water with Chloramines
Theoretical principles of water disinfection with chloramination are considered. It is shown that the use of ammonium sulphate in technology of water chloramination processes a number of advantages over water solutions of ammonia. The optimal conditions of ammoniation of the Neva River water for water supply stations of St. Petersburg have been determined.
Key words: potable water , disinfection, chlorammination, ammonium sulphate, ammonium chloride, safety, water supply stations
