A large stream has a re-oxygenation constant of 0.4 per day. At a velocity of 0.90 m/s and at the point at which an organic pollutant is discharged, it is saturated with oxygen at 9.2 mg/L (D-0). Below the outfall, the ultimate demand for oxygen is found to be 20 mg/L and the de- oxygenation constant is 0.2 per day. What be the DO at 50 km downstream?

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.
Suppose a wastewater has a BOD5 equal to 180 mg/L and a reaction rate (k) equal to 0.22/day. Find the ultimate carbonaceous oxygen demand (CBOD).
Discharge of waste water from a pulp mill results in an oxygen sag minimum value of 3.2 mg/L. At the point of discharge the river has a saturated DO value of 9 mg/L. The pulp mill isthe only source of BOD to the river. Given a river velocity of 2 m/s, an average depth of 5 m and kd of 0.22/day, calculate: the percent reduction of the BOD in the waste water to ensure a healthy river with > 5mg / L everywhere. the downstream distance that the DO minimum occurs the ultimate BOD of the river waste water mixture at discharge point so that DO minimum si 5 mg/L.
A lake with a volume of 10.0 x 10^6 m^3 that is fed by a stream with a flow rate of 5 m^3/sec and a pollutant concentration equal to 10mg/L. An industry dishcharges treated wastewater at a rate of 0.5 m^3/sec of the same pollutant into the lake at a concentration 100mg/L. The pollutant has a reaction rate constant of 0.20/day. Assuming pollutant is completely mixed in the lake and that ther is no evaporation and no other water losses or gains, determine the steady-state concentration of the pollutant in the lake.

A lake is fed by a polluted stream and a sewage outfall. The stream and sewage wastes have a decay rate coefficient (k) of 0.9/day (1st order units).

ENVIRONMENTAL ENGINEERING-WATER POLLUTION: The ultimate BOD of a river just below a sewage outfall is 50.0 mg/L, and the DO is at the saturation values of 10.0 mg/L. The deoxygenation rate coefficient, kd is 0.30/day, and the reaeration coefficient, kr is 0.90/day. The river is flowing at a speed of 48 miles per day. The only source of BOD on this river is this single outfall. FIND: The critical distance downstream at which DO is a minimum. The minimum DO. If a wastewater treatment plant is to be built, what fraction of BOD would have to be removed from the sewage to assure a minimum of 5.0 mg/L everywhere downstream?
A city of 20,000 people disposes of 1.05 m3/s of treated sewage that still has an ultimate BOD of 28.0 mg/L and 1.8 mg/L DO into a river. Upstream from the outfall, the river has a flow rate of 7.08 m3/s and a velocity of 0.37 m/s. At this point, the ultimate BOD and the DO in the river are 3.6 and 7.6 mg/L, respectively. The saturation value of DO (at the temperature of the river) is 8.5 mg/L. The deoxygenation coefficient is 0.61/day, and the reaeration coefficient is 0.76/day. Assume complete mixing and the velocity in the river is the same upstream and downstream of the outfall. What is the oxygen deficit and the ultimate BOD just downstream from the outfall (just after mixing, before any reaction can occur)?
Dissolved chloride in a concentration of 500 mg/L is being advected with flowing groundwater at a seepage velocity of 0.3 m/d in an aquifer with a porosity of 0.25. Groundwater from the aquifer discharges into a river. a. What is the mass flux of chloride into the river (in g/(m2d))? b. How long does it take the chloride to travel 100 m through the aquifer (i.e., the travel time for a 100 m distance)?
A well‐mixed sewage lagoon is receiving 430 m^3/d of untreated sewage. The lagoon has a surface area of 10 hectares and a depth of 1.0 m. The pollutant concentration in the sewage discharging into the lagoon is 180 mg/L. The pollutants degrades in the lagoon according to first‐order kinetics with a reaction rate constant of 0.70 d^‐1. Assuming no other water losses or gains and that the lagoon is completely mixed, find the steady‐state concentration of the pollutant in the lagoon effluent.
A river, flowing at 1.5 m3/s, is polluted with the pesticide permethrin and flows into a lake (100 m x 100 m 2.5 m). The steady state concentration of permethrin leaving the lake is 1.4 ppm and the average cross-sectional area of the river is 2.7 m2. The half-life of permethrin in this environment is 19 hrs. What is the concentration of permethrin entering the lake? What distance downstream of the outlet would the concentration be less than 1 ppm?
