The town of camp verde has been directed to upgrade its primary wwtp to a secondary plant that can meet an effluent standard of 25.0 mg/l bode and 30 mg/l suspended solids. they have selected a completely mixed activated sludge system for the upgrade. the existing primary treatment plant has a flow rate of 2,506 m3/d. the effluent from the primary tank has a bod5 of 240 mg/l. using the following assumptions, estimate the required volume of the aeration tank: 1. bod5 of the effluent suspended solids is 70% of the allowable suspended solids concentration. 2. growth constant values are estimated to be: ks =100 mg/l bod5; kd =0.025 d^-1 Ī¼m=10d^-1; y= 0.8mg vss/mg bod5 removed.3. the design mlvss is 3,000 mg/l.
