You are constructing a sewage lagoon with a 3,100 m3/day inlet/outlet flow rate. You must attain a BOD outflow load of 12 mg/L given a BOD inlet load of 26 mg/L. BOD has a half-life of 2.4 days.What volume is needed for the lagoon and how long would it take for the output BOD concentration to reach 1 ppm if freshwater started to replace the wastewater that was previously entering the lagoon?
You are building a wastewater lagoon with an inlet/outlet flow rate of 3,100 m3/day. The BOD inlet load is 26 mg/L and you need to achieve 12 mg/L at the outlet. The half-life of BOD is 2.4 days. What is the volume required for the lagoon? If the wastewater stopped entering the lagoon and was replaced by freshwater, how long would it take for the outlet BOD concentration to reach 1 ppm?
A city of 200,000 people deposits 37 cubic feet per second (cfs) of sewage having a BOD of 28.0 mg/L and 1.8 mg/L of DO into a river that has a flow rate of 250 cfs and a flow speed of 1.2 ft/s. Just upstream of the release point, the river has a BOD of 3.6 mg/L and a DO of 7.6 mg/L. The saturation value of DO is 8.5 mg/L. The deoxygenation coefficient kd is 0.61/day, and the reaeration coefficient kx is 0.76/day. Assume complete and instantaneous mixing of the sewage and river. (a) Find the initial oxygen deficit and ultimate BOD just downstream of the outfall.(b) Find the time and distance to reach the minimum DO. (c) Find the minimum DO.(d) Find the DO that could be expected 10 miles downstream.
Problem 5.27 Suppose the only source of BOD in a river is untreated wastes that are being discharged from a food processing plant. The resulting oxygen sag curve has a minimum value of DO somewhere downstream equal to 3.0 mg/L See figure P 5.27. Just below the discharge point, the DO of the stream is equal to the saturation value of 10.0 mg/L. By what percent should the DO of the wastes be reduced to assure a healthy stream with at least 5.0 mg/L of DO everywhere? Would a primary treatment plant be sufficient to achieve this reduction? Assume that a primary treatment plant removes 35% of BOD. If the stream flows 60 miles per day, has a reaeration coefficient kr equal to 0.80/day, and has a deoxygenation coefficient kd of 0.20/day, how far downstream (miles) would the lowest DO occur? What ultimate BOD (L0 mg/L) of the mixture of river and waste just downstream from the discharge point would cause the minimum DO to be 5.0 mg/L? d.Sketch the oxygen sag curve before and after treatment…
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 industrial plant discharges wastewater into a stream. The plant discharge has a flow rate of 0.2 m3/s and a BODu concentration of 40 mg/L. The stream receiving the discharge has a flow rate of 1.3 m3/s and a BODu of 6 mg/L. Downstream of the discharge point, the velocity in the stream is 0.15 m/s. Assuming no other sources of BOD enter the stream, what is the BODu remaining in the stream 10 km downstream of the plant discharge? Use k = 0.23 day-1.

Problem: 1. Design a facultative pond to treat (13500)gpm of sewage having (13500/20)mg/L of BOD. The average summer and winter temperature is 43oC and 13oC, respectively. Convert the same pond into aerated lagoon, if the concentration of influent BOD reaches to (13500)mg/L. 2. Determine the diameter of a trickling filter for a wastewater flowing at the rate of (13500)m3/day. The influent BOD (So) concentration for the wastewater is (13500 * 10)mg/L, whereas desirable effluent BOD should be as per NEQS.
