PROBLEMS, PERSPECTIVES

E. I. Pupyrev.
Problems of Water Disposal in the Clean Water State Program
The Clean Water State Program is dedicated to the problem of water supply to the inhabitants of Russia for communal and domestic needs as well as to the problem of treatment of wastewater generated upto an ecologically admissible level. The conception of the Clean Water Program contains an analysis of the state of water supply and water disposal systems in Russia, forecast of the situation development, choice of aim indicators, description of variants of tasks solution, determination of the dates and stages of their realization, estimation of financial expenditure, description of the expected results of the Program implementation.
Key words: The Clean Water Program, water supply, water disposal.

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
