A bio-tower composed of a modular plastic medium of 6 m is used as secondary treatment component in a municipal wastewater treatment plant. Flow from the primary clarifier is 25000 m³/day with 200 mg/1 BOD. The treatability constant is 0.06 per min. To produce an effluent with a soluble BOD of 20 mg/1, the surface area as per Eckenfelder (coefficient related to medium is 0.5) is approximately:

An activated sludge system using CSTR with sludge recycle has an influent flow rate (Q°) of 2.5 MGD that contains BOD of 200 mg/L. The volume of the aeration tank (CSTR) is 0.6 million gallons. The MLVSS (assume this is X,) in the aeration tank is 2000 mg VSS/L and the decay rate (b) is 0.1/day. The effluent from the secondary clarifier meets NPDES standards for suspended solids and BOD. The concentration of the settled sludge exiting the bottom of the secondary clarifier is 15,000 mg VSS/L. The sludge waste flow rate (Q") is 1 % of the influent flow rate, and the effluent flow rate (Qª) is ~99% of the influent flow rate. а) What is the hydraulic retention time, 0 (d)? b) What is the solids retention time, 0x (d)?
