Wastewater Treatment

Wastewater treatment is the process of converting wastewater into water that can be discharged back into the environment. According to the U.S. EPA, one of the most common forms of pollution control in the U.S. is wastewater treatment. The purpose of wastewater treatment is to speed up the natural processes by which water is purified.
