Abstract
AN INVESTIGATION OF THE CONCEPT OF A NEW APPROACH TOWARDS A HIGHLY EFFICIENT ELECTROCHEMICAL OZONE GENERATOR IS PROPOSED. THIS APPROACH IS BASED ON THE UTILIZATION OF AN OXYGEN REDUCTION CATHODE INSTEAD OF A HYDROGEN EVOLUTION RESULTING IN A SIGNIFICANT LOWERING OF REQUIRED CELL VOLTAGE. THIS APPROACH ALSO SIGNIFICANTLY SIMPLIFIES THE MASS BALANCE IN THE ELECTROLYZER. AN ENERGY REQUIREMENT OF 7.8KWH/KG OF OZONE IS PROJECTED FOR THE NEW ELECTROCHEMICAL METHOD COMPARED TO 16.5-22 KWH/KG FOR COMMERCIAL CORONA DISCHARGE GENERATORS. IN ADDITION, THE NEW APPROACH WILL PERMIT THE REDUCTION OF CONCENTRATED STREAMS OF OZONE (15-25% CONCENTRATION COMPARED WITH 2-3% FOR CONVENTIONAL GENERATORS). THIS WILL ENABLE THE DESIGN OF MORE ECONOMICAL PROCESSES AND EQUIPMENT FOR DISINFECTIVE TREATMENT OF WATER.
