ELECTROCHEMICAL METHOD TO SOFTEN CALCIUM SULFATE BEARING WATER Russian patent published in 1996 - IPC

FIELD: prevention of calcium sulfate sediments formation on heat transporting surfaces of water supply and water desalination systems. SUBSTANCE: method provides for electrolysis of treated water in anodic chamber of diaphragm electrolyzer, through which electrical current is passed in amount of 9.3 - 70.0 $$$. Any other water is fed in cathodic chamber of electrolyzer, for example, boiled down solution after evaporating aggregate. EFFECT: method allows to avoid calcium sulfate sediment formation on heat transporting surfaces of water supply and water desalination systems. 1 dwg, 1 tbl
