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 the industrial wastewater in MGD?
If the average BOD5 load from the domestic sewage is 0.18 lbs/capita-day, what is the average daily BOD5 loading (in lbs/day) from the industrial wastewater? What is the population equivalent to this BOD5 loading?

Q4. What are the quantitative requirements for BOD₅ and SS in wastewater discharges from secondary WWTPs? Hint:BOD₅ and TSS in the effluent must be less than or equal to 30 mg/L based on a 30 day average, and ≥85% removal of both must be achieved

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...

Two service lines in a wastewater treatment plant that feed the secondary aeration basin. The proportions of time that line 1 and line 2 are in use are given in term of the random variables of X and Y, respectively. The joint distribution describing the proportions X and Y of these two components is given by f(x,y)={23(x2+y2),0≤x,y≤10,eleswhere A. Determine if X and Y are independent. B. The plant needs to have an idea of the combined proportions of the two...

Consider the design of a wastewater treatment plant (WWTP) for a community with average daily and peak hourly wastewater design flows of 7570 m3/day and 18925 m3/day. The raw sewage has an average of 240 mg/L BOD5 and 270 mg/L of suspended solids. (a) Assume that the primary sedimentation process removes 55% of the suspended solids and 35% of the BOD5 of the raw sewage. Determine the SS and BOD5 concentrations in the primary sedimentation effluent flow. (1 mark) The...

You are provided the following information about a municipal wastewater treatment plant. This plant uses the traditional activated-sludge process. Assume the microorganisms are 55 percent efficient at converting food to biomass, the organisms have a first-order death rate constant of 0.05/day, have a maximum specific growth rate of 0.1/day, and the microbes reach half of their maximum growth rate when the BOD5 concentration is 10 mg/L. There are 150,000 people in the community (their wastewater production is 225 L/day-capita, 0.1...

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...
