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?

An industry generates 4 million gallons per day (MGD) (that is 15,000 m^3/ day) of liquid industrial wastewater having BOD5 of 1000 mg/L and first order reaction rate constant of 2.0/day. Because of the high BOD, there is a plan to build an industrial pre-treatment system at an industrial park. Effluent from the pre-treatment will be discharged into the city sewer for final polishing at the city wastewater treatment plant. Determine: a. Percent BOD removal if the wastewater is treated in one 5000 m^3 continous flow stirred tank reactor. b. Percent BOD removal if the wastewater is treated in one 5000 m^3 plug flow reactor. c. Percent BOD removal if the wastewater is treated in one 2500 m^3 continous flow stirred tank reactor followed by one 2500 m^3 plug flow reactor. d. Percent BOD removal if the wastewater is treated in one 2500 m^3 plug flow reactor followed by one 2500 m^3 continous flow stirred tank reactor. e.

A wastewater treatment plant discharges 2.16x107 L/hr of treated effluent with an ultimate BOD of 22.0 mg/L and dissolved oxygen concentration of 5.0 mg/L to a river. Upstream of the waste discharge, the river has a flow of 9.0 m3/s, an ultimate BOD of 10.0 mg/L, and dissolved oxygen concentration of 7.0 mg/L. Both the river and effluent are at 20°C. After the river and effluent mix, the river flows at a velocity of 0.13 m/s and has a depth of 1.8 m. The deoxygenation rate constant for the waste is 0.45 day-1. A fish hatchery is located 9.6 km downstream of the waste discharge. The hatchery requires 5.0 mg/L DO for healthy fish growth and reproduction. Is the hatchery requirement being met? show all work

A small town discharges its sewage effluent in a nearby river. The river has an initial background BOD of 23.5 mg/L.The oxygen deficit just upstream from the point of discharge of the sewerage is 4 mg/L. The river is flowing at aspeed of 43 km/day. You have been asked to determine the impact of this town’s sewerage discharge on the rivergiven that the deoxygenation rate coefficient kd is 0.3/day, and the reaeration rate coefficient kr is 0.5/day.a) A sensitive fish species inhabits the river 120 km from the point of discharge. Determine if the impact of theBOD will have led to the minimum DO before or after the location of the fish species.b) Find the minimum DO due to the effluent discharge.c) Discuss the oxygen deficit in relation to the location of the fish species and whether the fish are at risk due tothe discharge upstream.
Please calculate the theoretical OD, COD, and ultimate BOD of a wastewater containing (a) 500 mg/L acetate (CH3COOH), which is fully biodegradable; or (b) 500 mg/L oil (C40H80), which is not biodegradable.
As an operator of a wastewater treatment facility, you have learned that your plant runs well at an SRT (based on MLVSS (X) in the aeration basin) of 12 days. If today’s MLVSS (X) concentration is 2,700 mg/L and the RAS (Xr) concentration is 5,500 mg/L, how many L of sludge should you waste from the secondary clarifier today? Other design conditions: Average influent flow = 12,000 m3/d Influent soluble BOD = 150 mg/L Required effluent TSS = 30 mg/L Aeration tank Volume = 1,000 m3

The raw water supply for a community contains 160 mg/L total particulate matter. It isto be treated by addition of 86 mg/L alum.Essentially all of the added alum precipitatesby this reaction:Al2(SO4)3 · 14H2O ⇒Al(OH)3(s) + 3SO2−4 + 6H+ + 8H2O. For a total flow of 5500 m3/day, compute the daily alum requirement. Answer in units of kg/day. Determine the concentration of solids in the water following alum addition (i.e., the sum of the solids initially present and those formed during treatment). Answer in units of mg/L.
