ORGANIC REMOVAL MODULE FOR ULTRA-PURE WATER RECYCLE SYSTEMS

THE DEVELOPMENT OF A SYSTEM FOR THE REMOVAL OF ORGANIC COMPOUNDS FROM A HIGH PURITY WATER RECYCLE SYSTEM BASED ON SEMICONDUCTOR CATALYZED PHOTO-OXIDATION IS PROPOSED. THE COMBINATION OF A SEMICONDUCTOR CATALYZED PHOTO-OXIDATION ANDION EXCHANGE RESIN WILL PERMIT THE DEVELOPMENT OF A SIMPLE, COMPACT ORGANIC REMOVAL MODULE WHICH PROVIDES HIGHER REMOVAL EFFICIENCIES (SUB-PARTS PER BILLION TOTAL ORGANIC CARBON), LOWER MAINTENANCE, AND SUBSTANTIALLY SMALLER SIZE THAN EXISTING EXISTING SYSTEMS USING ABSORPTION ON CHARCOAL,OTHER SORBENTS, OR REVERSE OSMOSIS. THE PROPOSED SYSTEM WILL BE PARTICULARLY EFFECTIVE IN THE DESTRUCTION AND REMOVAL OF LOW MOLECULAR WEIGHT ORGANIC COMPOUNDS WHICH ARE NOT EFFICIENTLY REMOVED USING EXISTING TECHNOLOGIES. IF THERESEARCH AND DEVELOPMENT IS SUCCESSFUL, THE ORGANIC REMOVAL MODULE WILL BE AN INTEGRAL COMPONENT OF A COMPLETE HIGH PURITY WATER RECYCLE SYSTEM FOR USE IN THE PROCESS MATERIALSMANAGEMENT SYSTEMS IN FUTURE SPACE-BASED FACILITIES.
