Clarifiers

Final Clarifiers are also used to settle out microorganisms, or "bugs," from the activated sludge process. Clarifiers are usually either round or rectangular in shape.

Once the wastewater leaves the final clarifier, it is typically disinfected, to remove any bacteria. The solids are sent to a solids handling system, such as a solids thickener.
