Abstract
THE FUTURE ECONOMIC APPROACHES TOWARD ELECTROCHEMICAL OZONE GENERATION DEPENDS ON THE DEVELOPMENT OF LOW COST, STABLE, ANODE MATERIALS WITH LONG OPERATING TIMES. IN A PRIOR EPA SBIR PROGRAM (NOW IN PHASE II) ELECTROCHIMICA CORP. HAS DEMONSTRATED VERY SUCCESSFUL ELECTROCHEMICAL OZONE GENERATION METHODS FROM A VARIETY OF ELECTROLYTES OBTAINING HIGHER EFFICIENCIES AND OZONE CONCENTRATION LEVELS. PLATINUM ANODES HAVE TRADITIONALLY BEEN THE MATERIAL OF CHOICE. IT WAS DEMONSTRATED THAT WITH CERTAIN ELECTROLYTES LEAD DIOXIDE (PBO2) COATED ANODES CAN BE EMPLOYED AS A LOW COST SUBSTITUTE. EXTENDED STUDY RUNS HAVE SHOWN, HOWEVER, THAT EXTENSIVE CRACKING AND NON-ADHERENCE IS A SERIOUS PROBLEM. THIS BECOMES AN IMPORTANT AREA AFFECTING THE OUTLOOK FOR ELECTROCHEMICAL OZONE GENERATION. A NEW APPROACH IS PROPOSED FOR THE DEVELOPMENT OF SUBSTRATE MATERIALS AND PBO2 ANODES WITH LONG OPERATING LIVES AS A BASIS FOR LOW COST ELECTRO-CHEMICAL OZONE GENERATORS FOR DRINKING WATER TREATMENT.
