Abstract
Process and apparatus adds counterions into the aqueous solution of an electrode chamber of an electrolytic desalination or demineralization unit. In the demineralization unit, oppositely charged ions are electrolytically generated within electrode chambers and defused into the stream of aqueous solution to be demineralized. In their migration in response to the application of an electric potential, the ion streams are subjected to displacement steps in cation and anion exchange masses separated by selectively permeable ion exchange membranes. A counterion-containing liquid is subjected to an electrical voltage field, separate or in conjunction with the desalination unit, and the counterions to be added are passed through a selectively permeable ion exchange membrane into the respective electrode chamber of chambers of the desalination unit.
