Abstract: A novel electrode, an apparatus and a method are set out for electrolyzing a chloride ion containing aqueous solution to produce chlorine and ozone. Through utilization of a solid state rectifier network, and without the use of a transformer, full line voltage, after rectification, is applied between the anode and cathode of an electrolytic cell utilizing an anode which is a laminated body of a platinum group metal foil bonded to a tantalum or niobium layer which in turn is bonded to a titanium substrate. Chlorine and ozone production is quite rapid.

Abstract: Prior art electrolysis cells used for producing chlorine for sanitizing and sterilization purposes deteriorate due to accumulation of scale on the electrodes thereof. This problem is solved by an improved cell comprising an outer electrode having an in-facing surface which falls generally on a first cylindrical surface and an inner generally coaxial electrode having an out-facing surface which falls generally on a second cylindrical surface, the second cylindrical surface falling inward radially of the first cylindrical surface, the outer and inner electrodes being longitudinally coextensive for at least a substantial portion thereof. The inner and outer electrodes are rotated relative to one another. An abrading structure is mounted to one of the electrodes with an abrasive portion thereof in abrasive contact with the other of the electrodes. The abrading structure is electrically insulated from at least one of the electrodes.
