Water Treatment and Water Quality Control under the Conditions of Phytoplankton Development on the Example of the Moskva Water Source

Summary

Water bloom can influence significantly on the reliability of water supply of Moscow. The phytoplankton development depends on a whole number of factors: warming up and illuminance of water masses as well as availability of nutrients, biogenic elements (nitrogen and phosphorous mainly), in sufficient quantity are basic of them. Morphometric peculiarities of reservoirs and their hydrological conditions are of great importance. Quantity of phytoplankton changes appreciably year in year out. High concentrations of algae at certain periods favour the deterioration of organoleptic characteristics of water quality which complicates the process of water treatment. In that case it is necessary to carry out a whole number of measures beginning from redistribution of outflows from reservoirs and completing by introduction of innovation technologies of water treatment.
