What is the function of a clarifier in a wastewater treatment plant?

The clarifier serves a crucial role in a wastewater treatment plant by facilitating the process of settling and separating solids from liquids. During this process, the wastewater enters the clarifier where the flow rate is controlled, allowing heavier solid particles, such as sludge, to settle to the bottom. This settled material can then be removed for further treatment or disposal. The liquid that remains above the settled solids is typically clearer and can be treated further or discharged, depending on the treatment facility's processes. This function is essential for enhancing the overall efficiency of the treatment system, as it helps in reducing the turbidity of the water and concentrating solids for proper handling.
