Book excerpt: ABSTRACT: The NASA Advanced Life Support System (ALS) will provide systems for recycling water in manned flight space missions. A treatment process train is required in the ALS to convert wastewater into potable water on these missions. The reactor system described was designed to fill an ALS need for a final water treatment polishing process that will oxidize synthetic organic chemicals (SOC) and inactivate pathogenic microorganisms that are likely to contaminate wastewater systems on these missions. The reactor does not use expendable oxidation chemicals and uses a catalyst in a fixed bed, eliminating the need to separate the catalyst from the water after treatment.
