Abstract

The current state of water quality formation in surface water bodies, which serve as sources of drinking water supply in the Dnieper river basin, was considered. The water treatment technologies currently used in Ukraine, were analyzed. The inconsistency of these technologies with the current water quality in these sources of water supply was established, as these technologies are not quite suitable for the purification of water with a significant organic component of any genesis. It was found that one of the main factors that influences the quality of water in water bodies in the warm period is phytoplankton, especially during their "flowering. The factors accompanying this phenomenon were shown, the development trends and their influence on the operating water treatment systems were analyzed. It was considered the feasibility of using reagents with the effect of oxidation of the organic component of the source water, in particular chlorine dioxide, the use of which is effective in disinfection of chlorine-resistant microbiota and phenols oxidations. Moreover, in the conditions of the expected increase in the concentration of mycocystins, chlorine dioxide can be, by analogy with ozone, a fairly effective oxidant of these toxins with a prolonged disinfection effect.

The potential development areas of water treatment systems by intensifying bio-physico-chemical processes on the basis of the existing typical capacitive and package units of water treatment plants are given. The perspective areas of scientific and technological developments for substantiation of effective solutions on modernization of existing water treatment facilities were established in these conditions, namely it is reasonable to consider only those solutions, which provide effective purification of water with high concentration of phytoplankton without comprehensive or radical change of water treatment technology. That is, these approaches should make maximum use of existing treatment facilities, either by their reconstruction, or with the use of new reagents, or a combination of both.
