Waste water remains in aeration tank for 12 hours whereas biomass remain in system for 8 days. If incoming BOD to ASP is 240 mg/lit and waste sludge per day is 8775 kg and effluent biomass is negligible then removed per kg of biomass per day. Assume 78% of water supplied is converted into waste kg of BOD is water.

The plant operators at the Acme WWTP maintains the 10,000 gal aeration basin shown below with a constant 1500mg/L mixed liquor suspended solids (MLSS). The suspended solids are separated in a clarifier with recycle of the separated sludge. The recycle flow rate is 5,000 gal per day and 500 gal of recycle are wasted daily. Given that the plant treats 25,000 gals of liquid waste per day and the effluent contains 30 mg/L MLSS, find the solids retention time assuming the system is at steady-state.
Еxample Treatment plant with capacity 50*10° 1/day. This treatment plant required 20 mg/l alum. If the water alkalinity as CaCO3 is 6 mg/l. Find the yearly alum quantity and the quantity of CaO which is used as coagulant aid? Atomic weights: Al=27, 0=16, H=1, C=12, Ca=40
You are the lead engineer on a wastewater treatment plant with a biological reactor. You are required todetermine how much biomass will be produced in kg per day in your plant. A junior engineer determines theultimate BOD of the incoming waste as 600 mg/l, with a decay constant of 0.1/d. The incoming substrateconcentration used should be the five-day BOD. The incoming flow is 75 m3/d however there are lossesupstream of the plant accounting for 15 m3/d of the flow. The target BOD discharged from the plant is 25mg/l. the kinetic constants for the system are Ks = 90 mg/L BOD5, kd = 0.2 d-1, μm = 1.5 d-1, and Y = 0.6 mg VSS/mgBOD5. Include a sketch to illustrate the biological reactor and its incoming flows.
A municipal waste water has a BOD5 of 200 mg/L at 20 ˚C. The reaction rate constant k at 20 ˚C is 0.23 day-1.[5] a. calculate the ultimate CBOD.[5] b. calculate BOD5 at 15 ˚C.
A waste-holding lagoon situated near the main plant of a chemicalcompany receives sludge on a daily basis. When the lagoon is full, it is necessary toremove the sludge to a site located 4.95 kilometers from the main plant. Currently,when the lagoon is full, the sludge is removed by pumping it into a tank truck andhauling it away. This process requires the use of a portable pump that has an initialcost of $800 and an 8-year life. The company can operate the pump at a cost of $25per day, but the truck and driver cost $110 per day.Alternatively, the company has a proposal to install a pump and pipeline to theremote site. The pump would have an initial cost of $600, a life of 10 years, and acost of $3 per day to operate. (a) If the MARR is 15% per year and the pipeline willcost $3.52 per meter to construct, how many days per year must the lagoon requirepumping to justify construction of the pipeline? (b) The lagoon was pumped40 times last year. Which alternative would have been cheaper?…
A wastewater treatment plant treats a wastewater at a flowrate of 10 million liters per day. The wastewater has zero dissolved oxygen when it leaves the plant. The NPDES requirements include a minimum dissolved oxygen concentration of 2 mg/L in the discharge to protect the river. As an engineer, you must design a reaeration system to provide a minimum dissolved oxygen concentration of 3 mg/L (using a 1.5 safety factor). Use the reaeration data for the reactor with the largest volume to design a system. Assume each reactor that you used in lab represents the capacity of one aerator. How many aerators will be required to reaerate the water?
Problem 6. A new manufacturing facility is being located in your town. It plans to produce 2,000 m³/day of a wastewater that consists primarily of water and the chemical phenol dissolved in it at a concentration of 5 mg/L. Phenol has a chemical formula of C,H5OH. The company has asked the municipal wastewater treatment to consider treating this industrial waste. Your plant currently treats 30,000 m³/day with an average influent of 350 mg COD/L. a) Estimate the increase in COD loading (kg COD/day) if you accept the industrial waste discharge? b) Estimate the additional amount of oxygen (in kg O2/day) needed to oxidize the phenol at the treatment plant.

Xnew = 4,340 mg MLVSS/l)
Waste, measured as BOD, is removed according to first order kinetics at a rate constant of 0.4 min^-1. The wastewater flow rate is 27 m^3/min. The wastewater contains 216.5 mgBOD/L. To remove 80% of the BOD, how large (m^3) should the reactor be?
1. It is estimated that the BOD of raw sewage received at a treatment plant serving a population of 20,000 will be 300 mg/L. It is es1mated that the per capita BOD loading is 0.17 lbm/day. 30% of influent BOD is removed by settling. One single-stage high-rate trickling filter is to be used to reduce the plant effluent to 50 mg/L. Recirculation is from the filter effluent to the primary settling influent. Ten States' Standards is in effect, which specifies 100 gpcd in the absence of other information. (1) What is the design flow rate?
