Prospects of baromembrane desalination of brackish waters of the south of Ukraine

Prospects of reverse osmosis (RO) desalination of Azov seawater and brackis h water of the Berda River have been studied. It was shown that the efficie ncy of seawater desalination enhances with the increase of the ratio of ret entate to permeate fluxes, operating pressure and temperature of feed water . It was concluded that the complex treatment of brackish water at inland c onditions via a combination of RO with other chemical methods is the most c ost effective and environmentally appropriate way. The technological scheme for desalination of brackish water of sulphite type and for prevention of brine discharge has been developed. It permits production of both potable w ater and valuable mineral fertilizers as concentrated solution of K2SO4 wit h KCl additives.
