"The availability of water is a key element for enabling life in long-distance extra-terrestrial environments. Water is essential for consumption and hygienic use by the crew. Moreover, water is a fluid for thermal management systems, a barrier against high energy radiation, a source of hydrogen and oxygen and a solvent enabling multiple (bio)chemical reactions. Providing water for remote habitats in isolated environments is challenging due to logistics and constraints regarding energy, volume and weight requirements. This is also the case for the Antarctic Research Station Princess Elisabeth. The building is located 200 km inland and accommodates during the summer season up to 50 scientists and crew members. The configuration of a water treatment system depends on the nature of contaminants in the feed water and the quality objectives for the produced water. The best adapted technology to satisfy the requirements might combine biological processes, membrane technology, physicochemical processes, precipitation and electrochemistry. The limited renewable energy available from sun and wind, is only used for production of drinking water from snow when necessary. Recycling waste water consumes 80 % less energy than melting snow. The waste water of the station is treated by combined processes including anaerobic fermentation, nitrification and denitrification, filtration, adsorption and disinfection.
