Direct Osmotic Concentration System for Spacecraft Wastewater Recycling 2007-01-3035

Direct osmotic concentration (DOC) is a membrane treatment process for reclamation of space craft wastewater. It incorporates a novel system architecture that includes a forward osmosis (FO) and reverse osmosis (RO) subsystem for hygiene (gray) water, and a membrane distillation subsystem for the treatment of urine and humidity condensate. The products of these subsystems are combined and then post-treated by a catalytic oxidation subsystem. This paper documents progress made during the second year of a three year Rapid Technology Development Team (RTDT) effort.
