A mixture of cation-and anion-exchange resins, in proportions corresponding to their particular exchange properties and charged with calcium hydroxide, removes seawater salts from solution exchanging calcium hydroxide for the sodium chloride. The regenerant is recoverable. A portion of it may be used again without handling.
