Abstract
1,224,070. Electro-dialysis. SUMITOMO ELECTRIC INDUSTRIES Ltd. Dec.17, 1968, No.59855/68. Heading C7B. An electro-dialysis cell for demineralizing water is divided into a plurality of alternate desalination and concentration chambers 3 and 4 by alternately placed cation-exchange and neutral membranes 1 and 2, the end electrode chambers 5 and 6 being in contact with cathode 7 and anode 8 respectively. The liquid to be demineralized, e.g. sea water, is fed through channel 9, drinking water being extracted from channel 10. In operation, potential gradients higher than 10 volt/cm are applied in the desalination chamber. A porous neutral membrane may be prepared by dissolving PVC and tricresylphosphate into tetrahydrofuran, applying the resultant solution on polypropylene cloth, and after drying extracting the tricresylphosphate with methanol.
