Technology of Groundwater Treatment Based on Nanofiltration

Abstract

The work is devoted to studies on the treatment of brackish groundwater with an elevated iron content using polymeric nanofitration and precipitated ultrafiltration membranes. There was studied efficiency of treatment from iron compounds by means of precipitated membranes based on bentonite. of Milosky deposit in native form and bentonites with the addition of polyakrylamide and diallyl dimethyl ammonium chloride. There were investing permeability of the methods of the deposited membranes and the methods of their regeneration. There was proposed a basic process scheme for treatment of brackish groundwater with increased brackish groundwater content of iron.
