The purpose of the work is to establish the influence of various physical and chemical factors on the effectiveness of the processes of cleaning natural waters of various origins from toxicants of organic and inorganic nature and microbiological objects with environmentally safe reagents. Research methods: spectrophotometric, chemical analyses, UV spectroscopy, microbiological methods, biotesting, analytical calculations. Key results: The maximum degree of destructive mineralization of natural organic substances in water (85-88%) and the total degree of reduction of total organic carbon due to oxidation and coagulation (93%) in the photocatalytic (Fe3+/H2O2/UV) system were determined. Prospective options for plasma-chemical treatment of water systems with optimal modes of modeling aerosol structures for the deactivation of organic and mineral pollutants are proposed. Environmentally safe and relatively inexpensive composite microfilters based on fabrics from natural fibers for obtaining drinking water were obtained. Treatment of Dnipro water using such a composite microfilter reduced its color by 33.3o%, the content of aromatic compounds by 13.6o%, as well as genotoxicity and chronic toxicity. For the first time, the possibility of complete disinfection of E.coli and C.albicans in real natural waters of the mixed chloride-sulfate-hydrocarbonate type in the presence of heterotrophic organisms was shown (the total microbial number (TMN) was 0.8·10^3-7.0·10^3 CFUs/cm^3) with the combined action of environmentally safe reagents (CO2 and chitosan) and the presence of synergistic action of the indicated reagents in this process was confirmed.
