Design a circular radial-flow clarifier for a town with a projected population of 45,000. Assume that the wastewater flow is 400 L/capita-day. Size the system for a 2-hr detention time at average flow. Determine the tank depth and diameter to produce an overflow rate of 36 m/d for average flow.Assume standard tank dimensions to fit mechanisms made in diameters with increments of 1.0 m and depth increments of 0.5 m.
