4. Design a flocculation reactor to treat a flow rate of 16,400 m³/d, with a water temperature of 10°C,a mean detention time of 45 min, a basin depth of 3.5

m, and three flocculation stages, with the following G values for each stage: G1 = 50 sec-1, G2 = 35 sec1, G3 = 20 sec a) Determine the required surface area(in m2) for the flocculation reactor. b) Determine the power requirements (in kW) for each stage.
