Objects of research - different types of water (surface, underground); water solutions of salicylic and humic acids; chitosan; culture of mycelium fungi Aspergillus niger. The purpose of research is to establish the relationship between the physicochemical properties of water and the parameters of its purification by catalytic, membrane, electro-discharge, biological and reagent methods. Methods - spectrophotometric, atomic absorption, chemical analyzes; X-ray microanalysis, light microscopy, methods of counting colonies of microorganisms. Main results: The activity of synthesized samples nanosized TiO2 (N-TiO2 and (Fe,N)-TiO2 with different iron content (0–1% Fe)), having narrowed band gap, was investigated for photocatalytic degradation of different nature organic compounds in water using O2 and H2O2 at different irradiation modes (λ>200 nm or λ>360 nm). The expediency of using the system H2O2/TiO2/UV to increase the degree of salicylic and humic acids mineralization from all samples in a wide pH range under both irradiation regimes is shown in comparison with the system O2/TiO2/UV. The possibility of using low-energy plasma to purify water from surfactants was evaluated. The expediency of using and high efficiency of tubular microfiltration ceramic membranes from clay minerals in the purification of underground and surface natural waters by tangential microfiltration from suspended solids (>99,9%), Fe compounds (>99,8%) and Mn (>60%) has been proved. The parameters of the water defluorination by the method of "inline" coagulation-microfiltration with the use of FeCl3∙6H2O coagulant, which ensure purification of water from F− and Fe3 + ions to their norms in drinking water, were determined. The contribution of the Aspergillus niger flocculation by chitosan to the total water disinfection effect is revealed and the possibility of reducing the required reagent dose in the rational water treatment schemes choice is shown. The field of application - water treatment
