The largest rivers are the main source of water supply in Ukraine. Specific changes of water quality in main water supply sources are taking place due to climate fluctuation. There are changes in the nature of phytoplankton as well, which make existing water treatment plants work with difficulties. There is analyzed long-term research of water quality in Kyiv water intake during the period of active vegetation phytoplankton in this article. It was studied data from 2006 to 2011, years before the temperature jumped from 1983 to 1985 were taken for comparing. It was analyzed the relationship between color, turbidity, phytoplankton and its components, temperature, nutrients. They were taken the base correlations between each of the elements listed in the form of correlation matrices. It was made checking for compliance data distribution – normal. Correlation was determined by Pirsonm and Spearman. Based on these correlations the requirements for treatment facilities in accordance with the current temperature trend. One of the main conclusion is necessity to improve the ability of barrier structures for remove phytoplankton, manganese, soluble organic matter, color, and ability to provide such facilities to aeration source water.

Keywords: Phytoplankton, correlation, temperature, nitrate, nitrite, oxygen, water, pH, turbidity, color.

In present paper is submitted the review on perspective modern trends and approaches in practical realisation of anti-scale magnetic processing of water in power heat energetics and adjacent industries, including water processing for elimination of scale (carbonate, chloride and sulphatic salts Ca2 +, Mg2 +, Fe2 + and Fe3 +) in heat equipment, pipelines and sanitary systems. Principles of physical influence of magnetic field on water, parametres of physical and chemical processes proceeding in water, and behaviour of dissolved salts of rigidity in subjected to magnetic processing water are considered. It is shown, that magnetic field influence on water has a complex multifactorial character. The design features of devices of magnetic processing of water let out by the industry on constants and electromagnets – hydromagnetic systems (HMS), magnetic converters and magnetic activators of water are examined. It is given efficiency of using devices of magnetic processing of water in water preparation.

Keywords: water, magnetic processing, rigidity of water.

The analysis of hygienic, medical and ecological aspects of chlorine dioxide used as water disinfectant is given in the work presented. Chlorine dioxide provides an epidemic safety of drinking water due to a high viricidal, bactericidal and mycocidal effectiveness and CDO is not toxic either in the context of the influence on the laboratory animals organisms or concerning hydrobionts when dumping disinfected waste waters is shown.

e-mail: natand@normaplus.com

The review of data of the literature concerning the combined application of chlorine with ultraviolet irradiation (UVI) or ozone is presented. The analysis has shown, that efficiency of such combination in essential degree depends on a number of conditions which can be divided on two groups: the first – an optimality combination of certain doses for UVI and chlorine; the second – difference of influence of рН and temperatures for ozone and chlorine on efficiency of their combination with UVI.

Key words: water, purification, disinfection, chlorine, UVI, ozone, combination.
