Abstract
Supercritical water oxidation (SCWO) is a waste treatment and water recycling technology currently being developed for NASA by MODAR, Inc. Results are presented for SCWO of urine and feces in a laboratory unit sized approximately for an 8-person crew. Essentially complete conversion of organic carbon to CO2 or char, and of organic nitrogen to N2 and N2 O, were demonstrated. All major heteroatoms (S, P, Cl, Na, K, Ca, and Mg) were efficiently removed from the process stream as ash. A tradeoff study was carried out to evaluate which configurations of a SCWO subsystem would be most favorable for use in a space facility.
