Abstract:

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 Application:

Potential Commercial Applications:  This approach for removal of organic compounds
in high-purity water systems could be employed in electronics, pharmaceutical, and
biotechnology industries.
