Consider a disinfection process that destroys E. Coli in water. The reaction rate constant is k=1 day 1. The influent concentration of coliforms is 100 coliforms per mL of solution. The CSTR reactor volume is 400L and the flow rate in Qin and flow rate out Qout at steady operation are both at 1600 LPD (Liters-Per-Day). a) First, show how one obtains the steady state effluent concentration equation C=1+ktRC0 for the CSTR. Hint, start with the mass balance equation for the contaminant and work through the derivation to obtain the final equation offered in class. Finally, calculate coliform steady effluent concentration and reactor treatment efficiency in destroying E.Coli in CSTR reactor. b) Repeat the same calculation for the steady effluent concentration and reactor treatment performance (like in part a)) when the same volume and flowrate PFR reactor is used. Briefly, comment, which flow reactor (CSTR vs PFR) is preferred to remove E.Coli from the water at these conditions
