The aim of study: scientific substantiation of the choice and rational combination of chemical, physico-chemical and biological processes that are the most effective, ecologically and economically acceptable for the destruction and/or extraction of toxic or bioresistant organic compounds and inorganic ions, for creation of closed cycles of water usage. Research methods: spectrophotometric, atomic absorption, mass spectrometric with inductively coupled plasma, catalytic oxidative combustion, biotesting, determination of structural and sorption characteristics of sorbents. The expediency of the transition to closed water use cycles in Ukraine is substantiated. It was established that one of the most important conditions for achieving ecological and economic efficiency in the use of new carbonized activated sorbents for the purification of wastewater from organic compounds is a low initial content of the target component in water. The perspective of using PEI-modified montmorillonite and magnetite for wastewater treatment against heavy metal ions is shown. A high retention (99,6 – 99,9 %) of dyes of various chemical classes by a ceramic membrane modified with montmorillonite was established. The technological schemes for neutralization of regeneration waters of H+, Na+-cationite filters using reverse osmosis and electro dialysis are proposed. The advantages of photocatalytic (Fe3+/H2O2/UV) destruction of salicylic acid in water compared to other oxidation methods have been confirmed experimentally. The most sensitive test organisms for biotesting the quality of waters containing organic toxicants have been identified. Field of application: wastewater treatment; ecological assessment of water resources.  Product Description popup.authors Yezlovetska Inna S. Iievlieva Olha S. Balakina Marharyta M.
