Objective: The investigation of the isotopic composition influence on the water and its organic and inorganic contaminants content on the biological activity of drinking water through the use of complex chemical, physical-chemical, physical and biological processes. Methods: photocolorimetric, X-ray, chromatographic, spectral, biological testing. Main results: synthesized sol-gel by the method of matching photocatalysts based on titanium dioxide, and studied the physical and chemical properties of these materials. A method of applying the active phase of the catalysts on the matrix media. The effect of temperature and the nature of the electrolyte on the cluster structure of water. Some tendency to reduce the content of the clusters with increasing radius of the cation. The models of the reactors for photocatalytic water treatment processes to dry well and specific sources of exposure. Determined the dose of UV germicidal irradiation for effective inactivation micromycetes in water and experimentally demonstrated the effectiveness of its disinfection. The studies on the effect of chloride, sulfate, bicarbonate nanofiltration process for water purification in the presence of nitrates polyhexamethyleneguanidine. Found effective reagent-enhanced nanofiltration using polyhexamethyleneguanidine to remove nitrate ions from water. Proved that the bactericidal action of silver depends on the available solution of silver ions and the effect of disinfection depends on the physical and chemical composition of the medium and the size of the silver sols.
