International space station commander chris hadfield lifts the lid on the water recovery system the first liquid recycling system to be flown in space that cleans almost all the water.
Iss water recovery system.
Upgrades to the iss water recovery system the iss water recovery system wrs includes the water processor assembly wpa and the urine processor assembly upa.
Description of the iss water recovery and management system the iss wrm provides the capability to receive the waste water on iss crew urine humidity condensate and sabatier product water process the waste water to potable standards via the wrs and distribute potable water to users on the potable bus.
The iss has two water recovery systems.
There is an entire closed loop system onboard the iss dedicated to water.
Contes recycles water by using chemical or biological treatments to remove impurities and contaminants in wastewater to turn into clean drinking water.
The water recovery system wrs installed on the iss achieves a recovery rate of approximately 93 however the origin of this water can be from urine ambient air moisture from the astronaut crew s sweat and breath as well as even from their laboratory animals.
The wrs produces potable water from a combination of crew urine first processed through the upa crew latent and sabatier product water.
This paper summarizes water management activities on the.
Bob bagdigian of marshall space flight center talks about the extensive filtering process the water recovery system will use on the international space station to provide the crew with fresh drinking water.
By the end of the 1960s as work towards jf kennedy s pledge of putting a man on the moon by the end of that decade culminated in the historic apollo 11 landing it had become apparent that the future of human space exploration would require systems to recycle water and oxygen to be developed.
The major assemblies included in this system are the water processor assembly wpa and urine processor assembly upa.
How is water recycling achieved onboard the international space station.
