The osmotic distillation (OD) system is a membrane-based wastewater treatment process that can function as a water treatment system for long duration human space flight missions. This system was designed specifically to produce potable water from a mixture of human urine and humidity condensate. The process consists of two stages starting with osmotic distillation, which is followed by reverse osmosis. When treating a mixture of human urine and simulated humidity condensate, this system can produce water with a total organic carbon (TOC) concentration below 10 ppm. 4
