Abstract

568,129. Obtaining drinking water from sea-water. OCEAN SALTS (PRODUCTS), Ltd., ADAMS, B. A., and BOTT, H. R. April 10, 1943, No. 5779. [Class 46] Drinking water is obtained from sea-water by precipitating the chlorine ions as cuprous chloride and after separation treating the solution to eliminate the remaining cations and anions. For example, cuprous sulphate or anhydrous copper sulphate with spongy copper as a reducing agent is added to the sea-water and the whole agitated to precipitate cuprous chloride which is filtered off. The solution now containing mainly sodium and magnesium sulphates is treated with barium oxide to precipitate the sulphate and magnesium ions, filtered, and then passed to a cation-exchange column, where the sodium &c. ions are substituted by hydrogen ions. A suitable cationexchange material is a resorcinol condensation product which can be reactivated by tartaric or citric acid dissolved in sea-water; since that material is effective for hydrogen-ion substitution only when associated with anions giving an alkaline reaction ; thus, as the cations of this sea-water are associated only with chlorine and sulphate ions and not with hydroxyl ions, this sea-water will not enter into any exchange action.
