How do space stations keep the air breathable?
In: Engineering
They use an ILPE (Integrated low level electrolizer) to split hydrogen and oxygen apart from water (2 hydrogen 1 Oxygen in H2O). To clean co2, which is a byproduct of breathing, they use a scrubber. It basically uses MEA (a chemical) that absorbs CO2 from the air. Finally they have backup oxygen candles, which when burnt create oxygen chemically, as a backup and lithium hopcalite as a backup to the scrubbers, which is a byproduct of running the scrubbers.
