The correct answer is five. In an Activated Sludge plant, there are typically five critical components that play a vital role in the treatment process. These components are essential for the efficient functioning of the treatment system, and they include the aeration tank, clarifier, mixed liquor, return activated sludge (RAS), and waste activated sludge (WAS). Each of these elements contributes to the biological treatment of wastewater through the aeration process and subsequent separation of solids from the treated water. Understanding these components is crucial for the effective operation and management of wastewater treatment facilities.
