How is urine purified on the ISS?
To compensate for the microgravity environment, the NASA engineers developed a centrifuge-like pretreatment system. In this system, urine is piped into a rotating drum that spins at high speeds, extracting water vapor, which is then compressed in “a very energy-efficient distillation process,” says Bagdigian.
What would NASA use to recycle urine?
Hauling tons of water to the space station is inefficient and costly. In 2009, NASA astronauts began recycling urine using the Urine Processor Assembly, which is able to reclaim 75 percent of water from urine.
Do astronauts drink their recycled urine?
Water is heavy and hard to transport into orbit, which is why the International Space Station is a champion when it comes to recycling. Even astronaut urine is captured and processed to make it drinkable.
Can urine be turned into drinking water?
