The development of a system for the removal of organic compounds from a high purity water recycle system based on semiconductor catalyzed photo-oxidation will be conducted. The combination of a semiconductor-catalyzed photo-oxidation and ion-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 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. The organic removal module could be an integral component of a complete high-purity water recycle system for use in the Process Materials Management Systems in future space-based facilities.
Potential Commercial Applications:This approach for removal of organic compounds in high-purity water systems could be employed in electronics, pharmaceutical, and biotechnology industries.STATUS: Phase I Only
