A wastewater treatment plant that treats wastewater to secondary treatment standards uses a primary sedimentation process followed by an activated sludge process composed of aeration tanks and a secondary clarifiers. This problem focuses on the activated sludge process. The activated sludge process receives a flow of 15 million gallons per day (MGD). The primary sedimentation process effluent has a BOD5 concentration of 180 mgBOD5/L (this concentration is often referred as S). Before flowing into the activated sludge process, the primary...

A wastewater treatment plant with activated-sludge process treats wastewater for 120,000 m3/d. The effluent standard for both BOD and TSS is 20 mg/L. Influent TSS concentration is 450 mg/L and influent BOD concentration is 220 mg/L. MLSS concentration is 3500 mg/L (Assume no nitrification and temperature is 20°C). Determine: (20 pts) (a) Influent BOD and TSS concentration to the aeration tank if the treatment efficiencies in primary clarifier are 30% and 70% for BOD and TSS, respectively. (b) Determine sludge...

A municipal wastewater treatment plant discharges 20,000 m3/d of treated wastewater to a stream. The wastewater has a BOD5 of 30 mg/L with a k1 of 0.23 d-1. The temperature of the wastewater is 20 oC, and the dissolved oxygen is 2.0 mg/L. The stream just above the point of wastewater discharge flows at 0.65 m3/s, has a BOD5 of 5.0 mg/L, and is 90% saturated with oxygen. The temperature of the stream is also 20 oC. After mixing, the...
