Abstract
The Planetary Urine Processor (PUP) is a proposed urine distillation system for lunar or planetary applications, taking advantage of local gravity for phase separation as well as the movement and storage of waste feeds and product water. 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.
