Another significant chemical category in sewage water is nutrients, particularly nitrogen and phosphorus. These nutrients, primarily from fertilizers and agricultural runoff, can lead to eutrophication in water bodies upon entering sewage. Eutrophication is a process where excess nutrients promote algal blooms, depleting oxygen levels and harming aquatic ecosystems. The resulting dead zones can devastate fish populations and disrupt local economies reliant on fishing and tourism.

Chemical treatment processes involve the addition of chemicals to water or wastewater to facilitate the removal of contaminants. One of the most widely used chemical treatments is chlorination, which involves adding chlorine or chlorine-based compounds to disinfect water by killing pathogens. However, this method must be carefully managed, as excessive chlorine can lead to the formation of harmful by-products.
