After initial mixing of a wastewater discharge in a 5-m-deep river, the DO concentration in the river is 7 mg/L and the temperature is 22°C. The average flow velocity in the river is 6 cm/s.(a) If the ultimate BOD of the mixed river water is 15 mg/L, the rate constant for BOD at 20°C is 0.5 d−1, there is negligible removal of BOD by sedimentation, and the reaeration rate constant at 20°C is 0.7 d−1, estimate the minimum DO concentration in the river.(b) How far downstream of the outfall location will the minimum DO concentration occur?
Q2: A wastewater containing 300 mg/l SS and 250 mg/l BOD passes through a primary sedimentation tank of surface area 600 m². The flow is 15*103 m³/d. Estimate the effluent SS and BOD. (Use Figure 1)
12.50 Determine the activated-sludge aeration volume required to treat 2.64 mgd with a BOD of 120 mg/l based on the criteria of a maximum BOD loading of 40 lb/1000 ft³/day and a minimum aeration period of 5.0 hr. Assuming an operating F/M of 0.20 lb BOD/day per lb of MLSS, calculate the MLSS to be maintained in the aeration tank. Estimate the operat- ing sludge age (mean cell residence time), assuming an effluent suspended solids of 30 mg/l and the daily amount of waste-sludge solids from Figure 13.1. Determine the diame- ter and side-water depth of two identical final clarifiers of the type shown in Figure 10.12 for this activated-sludge system.
