Microbes are involved in which step(s) of wastewater treatment?

Question

Quizplus · Accepted Answer

Microbes are involved in the secondary step of wastewater treatment, where they digest and break down organic matter through biological processes. In the primary step, physical processes like sedimentation and screening are used to remove large solids and debris, without the use of microbes. Tertiary treatment may involve additional biological processes as well as chemical and physical treatments to further purify the water, but it is not always included in wastewater treatment processes.
