Abstract
This paper highlights important issues associated with urine in closed-loop life support systems and reviews chemical, biological, physical, and irradiative stabilization methods. Current methods for stabilizing urine for dumping to space vacuum on the shuttle and distillation on International Space Station are discussed. Alternative pretreatment methods are reviewed and compared to current practices. The effect of pretreatment on the chemistry of precipitation during distillation is presented. Theoretical maximum water recovery (maximum concentration factor) without precipitation and scaling is estimated. The major inorganic and organic compounds that would precipitate first are identified. The paper provides a framework for developers of urine collection, storage, and water recovery technologies to meet the requirements of a closed-loop life support system. Recommendations are based on the goal of maximizing water recovery from urine.
