The purpose of the study is to study the specifics of the processes on the surface of the phase distribution and in the volume for the deep extraction of various categories of typical pollutants from water using adsorption, membrane, photochemical and photocatalytic methods, plasma chemical conversion and biotesting. Research methods – spectrophotometric, catalytic oxidative combustion, biotesting, methods of determining the structural and sorption characteristics of sorbents. Modern approaches and integral indicators for evaluating the efficiency of wastewater reuse are considered. The transformation of different forms of chlorine at the stages of water disinfection with sodium hypochlorite, the specifics of their removal by carbon filters were studied. A method of regeneration of spent coal has been developed. The regularities of photochemical and homogeneous photocatalytic destruction of paracetamol in water by H2O2 and Na2S2O8 oxidants under UV and UV-C irradiation were established. The influence of the chemical nature of organic micropollutants of natural waters (for example, diclofenac sodium, paracetamol, sulfonamide, salicylic acid) on the efficiency of their removal in the processes of nanofiltration and reverse osmosis has been established. The main parameters of effective plasma chemical destruction of active violet 7 dye and cationic surfactant in the process of plasma chemical treatment were determined. Acute toxicity for Dafnia magna and chronic toxicity for Brahidanio rerio of sodium diclofenac, paracetamol and streptocide at a concentration of 0.1-10.0 mg/dm3 were established. The biotesting method established the need for further purification of the permeates of the reverse osmosis furnace for wastewater treatment. The field of application is water preparation and water treatment.  Product Description popup.authors Yezlovetska Inna S. Balakina Marharyta M. Baranov Oleksandr I. Vakulenko Vira F.
