Q3: A 500,000-gallon rectangular clarifier receive 7 millions gallons per day. The primary influent BOD concentration is 300 mgBOD/L. The primary influent TSS concentration is 350 mg/L and the sludge production is 10,000 lbsTS/ day.

a) What is the average primary effluent BOD concentration if the clarifier BOD removal rate is 30%?

b) What is the clarifier TSS removal rate (%)?

c) What is the expected average primary effluent TSS concentration

Problem #3: Biochemical Oxygen Demand (BOD) and Stream Quality A wastewater treatment plant designed for a community of 45,000 people has a flow of 100 gal/person/day and a BOD5 loading of 0.2 lb/person/day. The upstream characteristics of the receiving waters are: stream flow rate = 20 cfs and BOD5 = 2 mg/L The water quality standards require the in-stream BOD5 to be less than 7 mg/L in this stretch of the river. The minimum BOD removal efficiency that the treatment...

The volumetric flow to the ACME wastewater treatment plant is 25 MGD. The influent soluble BOD5 is 200 mg/L and the effluent soluble BOD5 is 8 mg/L. The plant is designed to operate with a mean cell (biomass) residence time of 10 days. The yield coefficient is 0.6 mg biomass/mg substrate, and the biomass decay rate is 0.09/day. The reactor is to operate at a biomass concentration of 2500 mg/L. The thickened underflow biomass concentration from the secondary clarifier is...

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...

You have been retained to design a wastewater treatment plant using a conventional activated sludge process for a town of 40,000 people. The industrial flow contribution to the sewer system is 300,000 gallons per day. Effluent discharge standards require effluent BOD5 and total suspended solids concentration of <10 mg/l. Assume the following design criteria are applicable: Domestic sewage flow = 100 gal/cap/day (including I/I) BOD loading = 0.18 lbs/cap/day TSS loading = 0.20 lbs/cap/day BOD removal in primary = 33%...

A 2,250 m3/day extended aeration system is used to treat sewage from Taman Maju Jaya. The average BOD influent of the sewage treatment plant is 250 mg/L and is reduced by 65% after the primary clarifier. It has two rectangular aeration tanks (working in parallel) with a dimension of 4 m width, 6 m length and 3.5 m water depth. The aeration tank maintains a biomass concentration of about 4000 mg/L. (i) Determine the food-to-microorganism ratio of the aeration tank...
