A lagoon with volume 1,000 m3 has been receiving a steady flow of a nonconservative pollutant with reaction rate of .20/day at a rate of 100 m3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 100 mg/L. Assume completely mixed conditions. If the input waste concentration suddenly decreased to 10mg/L, what would the concentration in the effluent be 10 days later?

You are designing a sewage lagoon to accommodate an input flow of 0.1 m3/min. At steady-state, the effluent (also at 0.1 m3/min) from the lagoon must not exceed a BOD of 10 mg/L. Assume the lagoon is well mixed, that there are no additional inputs to the lagoon and that the BOD degrades with a reaction rate constant equal to 0.1 day-1. What is the volume of the lagoon needed to achieve the effluent BOD goal if the influent BOD...

11. A lagoon with constant volume of 450,000 m' is being used to treat two separate waste streams. One has a flow rate of 5.0 m/s and a waste concentration of 500 mg/L. The other has a flow rate of 1 m/s and a waste concentration of 1500mg/L. The pollutant has a reaction rate coefficient (k) of 0.3/day. Assuming the pollutant is well mixed in the lagoon, find the steady-state concentration of pollutant in the lagoon. (10 Points)

A well-mixed lagoon is used to pre-treat an agricultural waste stream before it is sent to the local municipal wastewater treatment plant. The waste stream has a flow rate of 400 m3/d and contains 300 mg/L of biodegradable waste. The waste decomposes via a first- order biodegradation process with a rate constant of 0.35 d-1. How large must the lagoon be in order to drive the concentration of waste down to 20 mg/L (as required by the municipal wastewater treatment...

1. A lake with constant volume 10 x 106 m3 is fed by a pollution-free stream with a flowrate 50 m3/s. A factory dumps 5 m3/s of nonconservative waste with concentration 100 mg/L into the lake. The pollution has a reaction coefficient 0.25 day1. Assume the pollution is well mixed in the lake. Find steady state concentration of pollution in the lake.
