sewage treatment
Cleaning dirty water
Sewage treatment is the process of removing contaminants from wastewater before releasing it into the environment.
Municipal sewage treatment typically involves multiple stages—screening solids, breaking down organic matter with bacteria, and disinfecting the effluent.
The city upgraded its sewage treatment facility to handle population growth.
