Which type of waste is typically treated in a sewage treatment plant?

Sewage treatment plants are primarily designed to treat municipal waste, which consists of wastewater generated from residential and commercial activities. This type of waste includes substances such as food particles, soap, human waste, and various chemicals that are typically found in domestic environments. The treatment processes in sewage plants—such as screening, sedimentation, biological treatment, and disinfection—are specifically tailored to handle the composition of municipal waste.

Industrial waste, while sometimes treated in specific facilities, typically requires different treatment processes due to its varied and often more complex chemical nature. Hazardous waste presents additional regulations and treatment challenges, as it can contain toxic components that are not suitable for standard sewage treatment processes. Similarly, radioactive waste necessitates specialized disposal and treatment methods that are outside the capabilities of a conventional sewage treatment plant. Therefore, municipal waste is the correct choice as it represents the primary type of waste processed in these facilities.
