Abstract : Based on research and testing of several water recovery processes, the catalytic oxidation of waste water vapors (after vacuum distillation) to eliminate trace organic entrainment shows good promise for a water reclamation system for aerospace missions. This report summarizes the results of research and the design and development of two systems. The catalytic oxidation unit for both systems is operated at low temperatures (300 F versus past operating temperatures in the 1200 F range). This is the first known development of a satisfactory low temperature catalytic unit integrated with a vacuum distillation water reclamation system. Also discussed is the use of radioisotopes for the thermal energy. One system uses the vacuum of space to facilitate distillation of the water and transport of liquids and vapors. Electronic controls and electrical energy demand are held to a minimum. (Author)
