Urine is first treated by the Air Evaporation process to produce the distillate. Urine is reclamed as the feedstock for the production of oxygen by electrolysis. Hygiene water is reclaimed for re-use as hygiene water. Humidity condensate is reclaimed for use as drinking water and food preparation water. Salts are added to this water to improve taste.
Water is disinfected using silver ion.
