Abstract

517,902. Softening water. SUZUKI, H. Aug. 25, 1938, No. 25044. [Class 46] [Also in Group III] In order to prevent scale formation calcium salts are removed from sea water, brine, or other hard water by treating the water with a solution of alkali oxalate to which a small quantity of a soluble alkali salt, such as sodium chloride or sodium sulphate has been added, the solution of alkali oxalate having been obtained by heating the calcium oxalate, separated from water by earlier treatment, in a solution of alkali carbonate.
