Water Supply of the Crew of a Space Station Through Water Recovery and Water Delivery: SRV-K and SPK-U System Operation on ISS

Abstract

<div class="htmlview paragraph">The paper summarizes the experience gained with the ISS water management system during the missions ISS-1 through ISS-10 (since November 2 2000, through November 30, 2004). The water supply sources and structure, consumption and supply balance and balance specifics at various phases of space station operation are reviewed. The performance data of the system for water recovery from humidity condensate SRV-K and urine feed and pretreatment system SPK-U in the Russian orbital segment are presented. The key role of water recovery on board the ISS and the need to supplement the station’s water supply hardware with a system for water reclamation from urine SRV-U is emphasized. The prospects of regenerative water supply system development are considered.</div>
