Abstract

The ISS Urine Processor Assembly (UPA) began operations in November 2008. Though the UPA has successfully generated distillate from crew urine, several modifications and upgrades have been implemented to improve overall system performance throughout the years. Current and future upgrades to the UPA will continue to focus on improved system performance and reliability, focusing next on a flight demonstration experiment of a vacuum pump utilizing scroll pump technologies. The upgraded Distillation Assembly (DA), described in further detail in previous publications, will also be available for on-orbit integration within the year. The following paper discusses progress on the Purge Pump and Separator Assembly (PPSA) and concept considerations for future UPA upgrades.
