2. A reactor is needed to remove a contaminant Ca from an industrial wastewater. A 95% removal efficiency is required, and the following conditions apply: Steady-state, first-order reaction, flow rate = 23 m'/d and reaction rate coefficient k = 0.11 d'. a) Determine the volume of reactor required for an ideal CSTR. b) Calculate the hydraulic retention time. c) If Gn=114 mg/L and the volume from part (a) is divided into 3 CSTRS in series, find the effluent concentration and % removal. d) What would the ideal total volume for the 3 CSTRS in series be to achieve 95% removal? 2.
