Environmental Engineering: A lake with a constant volume of 10*106 m3 is fed by a pollution-free stream with a flow rate of 50m3/s. A factory dumps 5m3/s of a nonconservative waste with a concentration of 100mg/L into the lake. The pollutant has a reaction coefficient rate, k, of 0.25/day. Assuming the pollutant is well mixed in the lake, find the steady state concentration of the pollutant in the lake.
A lake with a constant volume of 10 x 10^6m^3 is fed by a pollution-free stream with a flow rate of 50 m^3/s. A factory discharges 5 m^3/s of a non conservative waste with a concentration of 100 mg/L into the lake. The pollution has a reaction rate coefficient K of 0.35/day. Assuming the pollution is well mixed in the lake, find the steady-state concentration of the pollution in the lake.
A lagoon with a volume of 1200 m3 has been receiving a steady flow Q = 100 m3/day of a non-conservative pollutant with a reaction rate constant k1 = 0.2 day-1 for a long enough time to assume that steady state conditions apply (there is an effluent stream flowing out that needs to satisfy steady state conditions). The waste entering the lagoon has a concentration of 10 mg/L.Assuming complete mixing conditions, what would the concentration of the pollutant be in the effluent leaving the lagoon?
Example A well mixed sewage lagoon (a shallow pond) is receiving 430 m5ja of wastewater from a sewer pipe. The lagoon has a surface area o 10 Ha and a depth of 1.0 m. The pollutant concentration in the raw sewage being discharged into the lagoon is 180 mg/L. The pollutarit in the raw sewage degrades biologically (decay) in the lagocn according to first order kinetics. The reaction rate constant is 0.7 /d. Assuming no losses or gains due to evaporation and rainfall and the lagoon is completely mixed, find the steady state concentration of the pollutant in the lagoon effluent.
250 lbs. of contaminated soil containing 0.500 g of a pollutant per kilogram of soil will be treated (remediation) by agitating the soil in a tank containing a suitable liquid phase to transfer the pollutant. Consider a tank holding 500 gal of liquid is built to treat 250 lb of contaminated soil. The pollutant degrades following a first-order kinetic in which 0.50 percent of it is removed per second. Assuming the reactor is operated for 2 hours, what will be: a) The mass of pollutant remaining in the washed soil b) The g/kg of pollutant remaining in the soil and therefore, the percent removal c) The concentration of the pollutant in the liquid phase

Determine the SS and BOD5 concentrations in the primary sedimentation effluent flow.
A rapidly mixed tank consists of a treatment unit used to disinfect a solution. The solution enters the 2000 m tank at a rate of 0.4 m/s. The pollutant contains 7.94 CFU per liter and has no 0 mg/l of chlorine. The treatment unit uses a stock solution containing 750 mg/L which is released a rate that will cause the chlorine concentration in the tank to be 2 mg/L. The chlorine reacts with the water in such a way that it is depleted at a rate (in mg/L-h) given by ra = ( -0.45/ h) Ca. When exposed to chlorine, the bacteria die off at a rate (in cells/L-s) given by: Cet Cbact Tbact Img + Ca a) Calculate the required flow rate in L/s of the stock solution when the system is operating at steady state, including a schematic of the system. b) Determine the bacterial concentration (in CFU/L) thar should be expected in the effluent from the tank?
1. A wastewater treatment plant serving a city of 200,000 discharges 1.10 m/s of treated effluent having an ultimate BOD of 50.0 mg/L into a stream that has a flow of 8.70 m/s and a BOD of its own equal to 6.0 mg/L. The deoxygenation constant ka, is 0.20/day. a. Assuming complete and instantaneous mixing, estimate the ultimate BOD of the river just downstream from the outfall. b. If the stream has a constant cross section, so that it flows at a fixed speed equal to 0.30 m/s, estimate the BOD remaining in the stream at a distance 30,000 m downstream. 2. The wastewater in the question above has a dissolved oxygen concentration of 2.0 mg/L and a discharge rate of 1.10 m/s. The river that is receiving this waste has BO equal to 8.3 mg/L, a flow rate of 8.70 m/s, and a temperature of 20°C. Assuming complete and instantaneous mixing, estimate the initial dissolved oxygen deficit of the mixture of wastewater and river water just downstream from the discharge point.
A stream containing no biochemical O2 demand (obviously a hypothetical situation) has a DO of 5.00 mg/L and a flow rate of 8.70 m3/s. The temperature of the stream is 15 degrees Celsius. The average velocity in the stream is 0.174 m/s. The average depth is 5 m. Determine the reaeration coefficient and the rate of reaeration.

Currently the food processing plant does not treat the waste. What percent removal ofthe BOD would be required to ensure that the DO of the river at any locationdownstream of the plant is always greater than 5.0 mg/L?b. How far downstream would the lowest DO levels occur?c. What ultimate BOD concentration of the mixture of the river and waste immediatelydownstream of the discharge would result in a minimum DO concentration of 5.0mg/L?
