2.8 Dairy wastewater is treated in a series of CSTRS. The initial con- centration of complex organics in the wastewater is 1500 mg/L. The first order rate coefficient is 0.45 d-1. Detention time in each reactor is 1.5 d. If two reactors are used in series, calculate the final effluent concentration of the organic matter. What is the conversion efficiency? 2.9 Using the data from Problem 2.8, calculate the overall efficiency if three reactors are used in series. Would it be feasible to use three reactors?
