Even astronauts on the International Space Station ISS enjoy drinking a Campari Soda from time to time – but where do they get the soda water from? There is no water in outer space, and the necessary quantities are much too heavy and bulky to be stored in tanks. That is why all liquids containing water are reused, but first they have to be collected and purified.
This workshop focuses on three different procedures for producing potable water from synthetic urine: distillation, filtration with activated carbon, as well as osmosis and reverse osmosis. At the same time, the effectiveness of these different purification methods is analysed using selected criteria.
