Abstract
Sweet whey is demineralized by an electrodeionization process by passing sweet whey to be demineralized through a resin bed of strong cationic exchange resin contained in an electrodeionization dilution compartment or through a resin bed of weak anionic and of cationic, particularly strong cationic, exchange resins in the compartment, and in the process, the pH of the wash solution present in the electrodionization cation and anion concentration compartments is maintained so that the solution present in each concentration compartment has a pH value less than 5.
