Abstract
A process for removing at least a portion of salts contained in whey or a liquid based on whey by means of electrolysis while producing an acid mixture and a base mixture useful in food industries. In the process a four-compartment electrolytic cell is used in the electrolysis of the whey or the liquid based on whey. The four compartments between an anode and a cathode are separated from each other by means of ion exchange membranes and an independent liquid recirculation is connected with each one of the four compartments of the electrolytic cell. A three-compartment cell is disclosed, in which anodes and cathodes, except at the ends of the stack, are replaced by bipolar membranes. The modified cell is similarly used on cheese whey concentrate, to produce an acid solution and a base solution.
