Scientists have been testing a new technology, the Brine Processor Assembly (BPA), to further recover water from urine and they have now succeeded.
Astronauts on board the International Space Station have produced water by collecting moisture and distilling pee, marking a huge advance for space travel.
The team used the Environmental Control and Life Support System (ECLSS) of the space station to reach this milestone.
The wastewater collection system is made to gather sweat and breath moisture and send it to the Water Processor Assembly (WPA), which turns it into drinkable water.
The pee Processor Assembly (UPA) also uses vacuum distillation to recover water from pee. However, the urine brine produced by this distillation process still contains some water molecules.
