✓ Problem 3: Two activated sludge tanks in Cobb County are operated in series. Each tank has the dimensions of 8 m width by 25 m length by 4.5 m effective liquid depth. The plants operating parameters are as follows: (2 points) 1. Flow-0.0596 m³/s. 2. Soluble BODs after primary settling = 139 mg/L 3. MLVSS=2,500 mg/L 4. MLSS=1.40 (MLVSS) 5. Settled sludge volume after 30 min - 203 mL/L 6. Aeration tank liquid temperature = 15°C. Determine the followings: aeration period, F/M ratio, SVI, solids concentration in the return sludge.
