ABSTRACT:
An improved assembly of bipolar electrode elements for use in the electrochemical preparation of hypochlorites or chlorine from dilute water solutions of chlorides, particularly mildly saline swimming pool water, is described. The end of each bipolar electrode element is enclosed in a nonconductive plastic strip, and guard baffles of corresponding thickness and height are inserted on each side of the bipolar electrode. A desired number of these elements are grouped and cemented together by solvent welding. Special adhesives enhance the sealing of the bipolar electrodes. With this electrode assembly, the deposition of mineral deposits on the electrode surfaces can be minimized by reversing the flow of direct current as often as twice a day or as seldom as once every two weeks.
