The PUP utilizes a stationary evaporator with an integrated disposable bag to process urine and capture remaining precipitates. This system aims to increase water reclamation percentage, reduce resource requirements, and enhance reliability/maintainability due to lower system complexity over the existing water recovery system used on the International Space Station (ISS). This paper focuses on the hardware development and testing efforts and the associated urine pretreatment development work.application/pdfengPartial GravityDistillationPlanetary Urine ProcessorUrine ProcessorStationary EvaporatorDisposable Bagwater reclamationurine pretreatmenthydrogen peroxidePresentations
