Description

The general regularities of water purification processes from organic and inorganic pollutants of various kinds were investigated by means of advanced physicochemical methods and defined main directions for perfection of those processes. The philosophy for tuning of novel heterogeneous catalysts based on syntetic zeolites, layered metallo-silicates and mixed oxides was developed for oxidative decomposition of dyes and reduction of nitrate ions in water medium. It was demonstrated that net effect ozone and UV-radiation increases the rate and extent of destruction of aromatic structure of organic admixture present in natural water purification employing a low pressure back osmosis, nano-filtration over ceramic membranes.Вased on the investigation results of water purification by baro-membrane processe, the block facilities possessing different productivity were elaborated for the quality improvement of graundwater and surface water serving as a drinking water suppliers.
