2. Design a circular clarifier for a flow rate of 34,560 m³/d. Use a design overflow rate of 30 m³/d-m². Assume the clarifier has a center feed and a side water depth of 4.3 m. Use a feedwell detention time of 20 min. Provide the following information to support your design: • Diameter of the clarifier • Diameter and depth of the feedwell . Check the flow velocity across the sludge zone • Calculate the weir loading rate
