This work lies in the range of science topics on creation of low-waste demineralization technology of light-salted natural and waste water. The aim of this work is to study the sorption processes of chlorides and sulfates on anion exchange resin AV-17-8 in basic form for development effective way of water mitigation and demineralization without using cation exchange resin. Scientific novelty of such method is determination of the dependence of efficiency of softening and desalting water with high sulfate content from the ionic composition of the water, ion form and its regeneration conditions. Ion exchange method of water treatment is based on the use of high-basic anion exchange resin in OH- form in dynamic conditions. Practical importance of this research is the development of a convenient method for treatment of mine water and baromembrane desalination concentrates of water that provide a creation of low-waste demineralization processes of water with high salinity.
