Design a low rate trickling filter for secondary treatment of sewage generated from 10,000 persons with rate of water supply 170 liters per capita per day. The BOD5 after primary treatment is 110 mg/L and BOD5 of final effluent should be 20 mg/L. Consider the following equation, where C = 5.358. (St/So)=(1)/(1+C((D^0.67)/(QL^0.5)) Now, design a high rate trickling filter for the data given above except effluent BOD5 is 40 mg/l since polishing treatment is provided after high rate trickling filter....

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 sewage treatment plant located along a river reported a chemical spill which may have released mercury into the river. The local environmental regulatory agency requires that such spills be monitored, and any spill that results in a long term mercury level above 2.5 µg/L (micrograms per litre) requires the party at fault to pay a large fee. A random sample of 58 measurements showed a mercury reading near the treatment plant to have a sample mean of 2.7 µg/L...

Q3. You have been selected to design a secondary wastewater treatment plant for a municipality in Amman of 15,000 people which has some industry that discharges wastewater to the municipal sewer system. The average daily wastewater flow is 2.1 MGD (million gallon/d) and the raw sewage entering the WWTP has an average BOD5 of 240 mg/L and average suspended solids of 260 mg/L. If the average domestic per capita sewage flow is 115 gpcd, what is the average flow of...
