The wastewater is filtered to remove solids and poured into a settling tank to get rid of higher viscosity impurities. It is then aerated to support pollutant-consuming bacteria. The treated water is poured into another settling tank to get rid of most the other impurities, and it is then filtered to get rid of any remaining particles.
Seawater -> Water
First method: Multi stage flash distillation (implemented)
Second method: Reverse osmosis with a cellulose triacetate filter
Wastewater -> Water
