A very interesting video on how wastewater is turned into clean water at a typical sewage treatment plant ...
Most sewage treatment is biological (natural bacteria) encouraged by heat and stirring up of the sewage. Then there is screening. Chemicals are used very sparingly in sewage treatment, due to the the risk of chlorine disinfection byproducts, which cause cancer.
