Prevention of calcium precipitation in the electrodialytic demineralization of whey
Abstract
Abstract A BENEFICIAL SIDE EFFECT OF THE HYDRAULIC PRESSURE INEQUALITY IS AN APPARENT REDUCTION IN MEMBRANE POLARIZATION. WHEY IS DEMINERALIZED IN A MULTICHAMBER ELECTRODDIALYSIS CELL COMPRISING ALTERNATING ION EXCHANGE MEMBRANES AND NEUTRAL MEMBRANES. CALCIUM PRECIPITATION OCCURRING IN THE CELL PRIMARILY IN ITS CONCENTRATING CHAMBERS ON THE FACE OF THE ION SELECTIVE MEMBRANES BORDERING THE CONCENTRATING CHAMBERS, AND CAUSED BY ACCIDENTAL WHEY LEAKAGE IN THE CONCENTRATING STREAM, IS PREVENTED BY A HYDRAULIC PRESSURE DIFFERENTIAL BETWEEN THE CONCENTRATING STREAM AND THE WHEY STREAM CAUSING, IN THE EVENT OF HYDRAULIC LEAKAGE, CONCENTRATE TO PASS INTO THE WHEY STREAM RATHER THAN WHEY TO PASS INTO THE CONCENTRATING STREAM.
