A process for the demineralization of whey or a liquid based on whey and for producing an acid mixture and a base mixture useful in food industries

摘要

The invention relates to 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 usable in food in­dustries. In the process a four-compartment electro­lytic cell (1) is used in the electrolysis of the whey or the liquid based on whey. The four compartments (A, B, C, D) between an anode plate (2) and a cathode plate (6) are separated from each other by means of ion exchange membranes (3, 4, 5) and an independent liquid recirculation (7, 8, 9, 10) is connected with each one of the four compartments of the electrolytic cell.
