SRV-K Status aboard the International Space Station and Water Recovery Future Prospects

2004-07-19
2004-01-2489
The paper deals with the performance data of the service module Zvezda integrated water supply system of the International Space Station (ISS) as of March 31, 2004. The water supply and demand balance are analyzed. It is shown that water recovery from humidity condensate has been especially important when water delivery by Space Shuttles was terminated. The SRV-K contribution in potable water supply for crew needs was up to 76%. The data of humidity condensate and recovered water compositions are reviewed. The effective cooperation of the international partners on part of life support is shown. Water recovery future prospects are discussed.

Testing and Operation of the Purification Unit of the System for Water Recovery from Humidity Condensate (WRS-C) with a Higher Content of Organic Contaminants

The paper presents the results of ground and flight (on OSS Mir) tests of an updated purification assembly of the WRS-C system outfitted with a filter-reactor. The tests have proved that the filter-reactor oxidizes effectively basic organic contaminants in humidity condensate including ethyleneglycol to ones that easily undergo sorption, enables the operation of the recovery system in the event of an off-design increase in organic contaminants in condensate and significantly improves the lifetime of the purification assembly. The data obtained confirm a wise selection of the purification assembly hardware for the system for water recovery from humidity condensate WRS-CM for the ISS service module.

Updated Systems for Water Recovery from Humidity Condensate and Urine for the International Space Station

1997-07-14

At the initial phase of the construction of the international space station (ISS) water supply will be provided by the systems located in the Russian segment. The paper reviews the systems for water recovery from humidity condensate and urine to be incorporated in the Russian segment of the ISS. The similar systems have been successfully operated on the Mir space station. The updates aim at enhancing system cost-effectiveness and reliability. The system for water recovery from humidity condensate (WRS-C) features an added assembly for the removal of organic contaminants to be catalytically oxidized in an air/liquid flow at ambient temperature and pressure. The system for water reclamation from urine (WRS-U) incorporates a new distillation subsystem based on vacuum distillation with a multistage rotary distiller and a vapor compression or thermoelectric heat pump. The updating of the WRS-C system will enable an increase in the multifiltration bed's life at least two fold.

This paper describes the results of research and tests of different patterns of distillation processes for water reclamation from urine accomplished by NIICHIMMASH in cooperation with other companies. Several typical patterns of evaporation to air flow from water-retentive porous bodies, from the surface confined by capillary/porous membranes and from free liquid surface in rotary units under atmospheric and reduced pressure are analyzed. Relevant condensation processes are reviewed. Performance data for distillation unit of SS MIR system for water reclamation from urine are outlined. The paper highlights the prospects of distillation hardware development.
