Experience in Development and Operation of a Regenerative System for Water Supply on Mir Space Station

The performance of the system for water recovery from humidity condensate (SRV-K) and the system for urine feed and pretreatment (SPK-U) on Russian segment of the ISS (missions 1 through 33)

“…This module will be outfitted with an updated system for water reclamation from urine SRV-UM. Unlike the system for water reclamation from urine SRV-U installed on space station Mir the SRV-UM system features vacuum distillation with a multistage rotary vacuum distiller and a thermoelectric heat pump [2,3,4]. At the processing rate of distillation of 2.5 L/hr energy consumption (including power of distiller engine) will be not more than 150 W-hr per 1 liter of processed condensate.…”
