The investigation purpose - the concept development of control of biological activity and physico-chemical properties of water, including its isotopic composition during the purification of natural waters in accordance with modern requirements for the quality of drinking water. The investigation methods - X-ray diffraction, thermal gravimetric, spectrophotometric, chemical analyzes; adsorption, light microscopy, small-angle scattering of the laser beam, complex biological testing. Main results: There have been synthesized modified catalyst and photocatalysts samples, there have been studied their effectiveness at a joint application with strong oxidising agents for the degradation of organic compounds; unit with TiO2 catalyst immobilized has been designed and conditions for maximum destruction of fulvic acid and anionic surfactants have been established.The modified natural polysaccharides - environmentally flocculants and adsorbents were obtained and efficiency of the colloidally dispersed, molecular and ionic impurities removal from the water were clarified. Role of deuterium at the formation of water cluster structures and in the water membrane transport have been studied. The recommendations on the use of ultrafiltration - nanofiltration for color Dnieper water purification have been developed. There were determined conditions for the effective removal of arsenic compounds, nitrate and phosphate ions, organic substances of various origin from water, by means of membrane processes. High cleaning efficiency of real groundwater from nitrate ions to the MPC requirements for drinking water was confirmed. The devices to measure the concentrations of suspended matter and nitrate in the dynamic mode were developed. A method for detecting microorganisms present in uncultivated state in water has been developed. The need to develop new approaches to its disinfection has been proven. The methods of combined treatment of water systems in an integrated action electric plasma technique and UV processing or coherent ultrasound and UV treatment, to improve the purification from microfungi and organic impurities have been proposed.The advantages of cytological preparations of blood cells during the study of toxic and genotoxic effects of aquatic environment pollutants have been justificated. As a result, the complex biological testing of pump water, tap water and water, treated with unit "Vega", was proved that natural and drinking water, which are normal chemical parameters, may be different for biological properties.
