A sewage lagoon that has a surface area of 50,000m2 and a depth of 2m is receiving 8500m3d-1 of sewage containing 150mg/L of biodegradable contaminants. At steady state, the effluent from the lagoon must not exceed 20mg/L of biodegradable contaminant. Assuming the lagoon is well mixed and that there are no losses or gains of water in the lagoon other than the sewage input. What is the biodegradation reaction rate (d-1) for a first order reaction
