Your firm has been asked to design a new secondary clarifier for a conventional activated sludge plant. The MLSS concentration is 3,000 mg/L, the flow rate is 8,000 m3/d, and the recycle ratio is 0.46. The desired RAS concentration is 10,000 mg/L. Use the following column settling data (Peavy et al., 1985): MLSS, mg/L 1,400 2,200 3,000 3,700 4,500 5,200 6,500 8,200 Settling velocity, m/h 3.0 1.85 1.21 0.76 0.45 0.28 0.13 0.089 To complete the design, provide the limiting solids flux rate, solids loading rate, diameter, and the overflow rate. Then, verify that the overflow rate is acceptable.
