TECHNOLOGY TRANSFER OPPORTUNITY: Contaminated Water Treatment (TOP2-106)

NASA’s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Ames have developed a method and system that offers a novel way of processing and recycling of liquids to remove contaminants. Space exploration requires a life-support system that sustains astronauts on journeys lasting from a few days to several weeks or longer. The life-support system must be designed to reduce the mass required to keep humans alive in space. Water accounts for about 80 percent of a humans daily mass intake. As a result, recycling water, including urine, offers a high return on investment for space exploration missions as well as increasing mission safety. It provides an emergency supply of drinking water, when other sources are exhausted or contaminated. This invention is a system and associated method that is a two step process. It provides a contaminant treatment pouch, referred to as a urine cell or contaminant cell that converts urine or another liquid containing contaminants into a fortified drink, engineered to meet human hydration, electrolyte and caloric requirements. It uses a variant of forward osmosis (FO) to draw water from a urine container into the concentrated fortified drink as part of a recycling stage. An activated carbon pretreatment removes most organic molecules. Salinity of the initial liquid mix (urine plus other) is synergistically used to enhance the precipitation of organic molecules so that activated carbon can remove most of the organics. A functional osmotic bag is then used to remove inorganic contaminants. If a contaminant is processed for which the saline content is different than optimal for precipitating organic molecules, the saline content of the liquid should be adjusted toward the optimal value for that contaminant.
