Sewage treatment plants play a crucial role in environmental protection and public health. They are facilities designed to treat wastewater from various sources, such as domestic sewage, industrial effluents, and stormwater runoff. The treatment process typically involves several stages, including physical, chemical, and biological processes, to remove contaminants, pollutants, and pathogens from the wastewater before it is discharged back into the environment or reused. This helps to prevent water pollution, protect water resources, and ensure the safety of drinking water and aquatic ecosystems. Sewage Treatment Plant
