In some cases, tertiary treatment is applied to further purify the water, removing nutrients and fine suspended solids that might have passed throughthesecondarytreatment. Before discharging the treated water, disinfection is necessary to eliminate re- maining harmful pathogens. Common disinfection methods included chlorina- tion, UV radiation, and ozonation.

STPs are vital for safeguarding public health, protecting aquatic ecosystems, and preserving water resources. Proper operation, regular maintenance, and adherence to environmental standards are crucial to ensuring that sewage treatment plants efficiently remove pollutants, producing environmentally safe effluentforthebenefitofsocietyandtheenvironment.
