A lagoon with volume 1,200 m3 has been receiving a steady flow of a conservative waste 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 10 mg/L. assuming completely mixed conditions,

(a) What should be the concentration of pollutant in the effluent leaving the lagoon?

(b) If the input waste concentration suddenly increased to 100 mg/L, what the concentration in the effluent be 7 days later?

C)A Nonconservative of pullutant with rate constant k=0.20/d.
