Abstract

As part of the work, an alternative environmentally friendly technology for water treatment of natural waters was proposed and tested, based on the combined use of hydrodynamic water treatment and ultrafiltration on ceramic membrane filters. The hydrodynamic characteristics of the treated water flow have been determined to achieve the maximum intensification of the oxidation processes of ferrous iron and manganese ions without the use of additional air ejection. The modes of hydrodynamic treatment of natural waters with additional air ejection were selected. The possibility of associated removal of highly corrosive admixture of dissolved hydrogen sulfide from natural waters and a decrease in the total hardness of the treated water has been established. The high efficiency of membrane tubular filters in the processes of removing dispersed impurities has been confirmed.

Keywords: Water purification, deferrization, hydrodynamic treatment, ultrafiltration, ceramic membranes
