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 lago

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.
