A NOVEL ADVANCED OZONATION PROCESS FOR THE DESTRUCTION OF CHLORINATED AND NON-CHLORINATED ORGANICS

"ADVANCED OZONATION PROCESSES" (I.E., THE COMBINATION OF OZONE WITH HYDROGEN PEROXIDE OR UV LIGHT), HAVE APPLICATIONS TO THE REMOVAL OF ORGANIC POLLUTANTS FROM WATER. ONE OF THE MAIN BARRIERS TO IMPLEMENTING AOPS HAS BEEN THE HIGH CAPITAL AND OPERATING COSTS FOR OZONE GENERATION. LYNNTECH, INC., HAS DEVELOPED AN ELECTROCHEMICAL DEVICE FOR THE PAIRED SYNTHESIS OF OZONE AND HYDROGEN PEROXIDE FROM WATER AND OXYGEN IN A PROTON EXCHANGE MEMBRANE-BASED ELECTROCHEMICAL CELL. THIS PROCESS FOR GENERATING OXIDANTS ELECTROCHEMICALLY CAN ELIMINATE MANY OF THE PROBLEMS IN MAKING AOPS COMMERCIALLY ATTRACTIVE. THE ADVANTAGES OF PAIRED ELECTROCHEMICAL SYSTHESIS OF O3 AND H2O2 IN ELECTROLYTE-FREE WATER INCLUDE; (A) LOWER OPERATING COSTS, AS TWO OXIDIZING AGENTS CAN BE OBTAINED FOR THE PRICE OF ONE; (B) LOWER INITIAL CAPITAL COSTS OF OZONE GENERATION; (C) THE ELIMINATION OF THE NEED FOR TRANSPORTATION AND STORAGE OF OXIDANTS BY GENERATING THEM ELECTROCHEMICALLY WITHIN WATER ON DEMAND AT AN AMOUNT THAT IS PROPORTIONAL TO THE WASTE CONCENTRATIONS, AND (D) THE PROCESS CAN GENERATE SIGNIFICANTLY HIGHER AQUEOUS PHASE OZONE CONCENTRATIONS THAN CAN BE OBTAINED USING TRADITIONAL METHODS OF OZONE FORMATION. RESEARCH WILL FOCUS ON DEVELOPMENT OF A LABORATORY TEST SYSTEM FOR WATER TREATMENT INCORPORATING THE ELECTROCHEMICAL DEVICE AND A UV-LIGHT REACTOR. TESTING WILL DEMONSTRATE THE FEASIBILITY OF THE SYSTEM FOR THE DESTRUCTION OF DISSOLVED CHLORINATED AND NON-CHLORINATED ORGANICS AND WILL PROVIDE PARAMETRIC DATA FOR SCALE-UP ACTIVITIES.
