Detailed explanation-1: -First, Astronaut wastewater is captured, such as urine, sweat, or even the moisture from their breath. Then impurities and contaminants are filtered out of the water. The final product is potable water that can be used to rehydrate food, bathe, or drink.
Detailed explanation-2: -Drinking water is something many of us take for granted on Earth, but on space missions it is harder to come by. The ISS recycles much of its water using chemicals, but it still relies on sizeable shipments of water from Earth to give its astronauts access to clean water.
Detailed explanation-3: -The goal of NASA’s recycling water system was to reduce the need for supplies to be shipped from Earth. It also means that astronaut crews would be able to endure longer space missions as a result.
Detailed explanation-4: -Astronauts can process small pieces of trash in a high-temperature reactor, which breaks the waste down into water, oxygen, and other gases which the crew can use or vent as needed. Besides the gases, the remainder of the waste is greatly reduced in size, and no longer biologically active.
