The purpose of research - investigation of combined effects with a joint action of chemical, physical and biological processes in water. Methods - spectrophotometric, atomic-adsorption, mass-spectrometric with inductively-coupled plasma (ICP-MS), chemical analyzes; light microscopy, small-angle scattering of a laser beam with subsequent computer processing, methods for counting colonies of microorganisms, three-wave photometry. Main results: New samples of photocatalysts based on titanium dioxide with a narrowed forbidden band were synthesized and their activity was studied in the oxidation of humic acids in water, depending on the irradiation regime. The composition of atmospheric aerosols under technogenic impact conditions and the process of their activation in an electromagnetic field with the perspective of using anthropogenic smog formations for water systems treatment and remote control has been studied. The effect of corona discharge on the formation of hydrogen peroxide in various types of water and the destruction of aqueous solutions of surfactants has been studied. The regularities of natural waters purification from fluoride ions and micro impurities As (III) by barometric methods (low-pressure reverse osmosis, ultrafiltration, nanofiltration) and their combination with adsorption, VUV- irradiation or TiO2/VUV- treatment are studied. Effective polysaccharide materials have been developed for water treatment and disinfection to obtain genetically safe drinking water. Small-sized autonomous modules for drinking water quality control based on modern semiconductor emitters and receivers have been developed. The field of application - water treatment.
