You are designing a reactor that uses chlorine in a plug flow reactor or a completely stirred tank reactor to destroy pathogens in water. A minimum contact time of 30 min is required to reduce the pathogen concentration from 100 pathogens/L to below 1 pathogen/L through a first-order decay process. You plan on treating water at a rate of 1,000 gal/min. (a) What is the first-order decay rate constant? (b) What is the minimum size (in gallons) of the reactor required for a plug flow reactor? (c) What size (in gallons) of CSTR would be required to reach the same outlet concentration

3. A CFSTR receives a flow rate of 100 m³/sec. There is one influent stream coming into the reactor and one effluent stream leaving the reactor. The concentration of a chemical in the influent stream is reduced by 95% in the reactor. Given, the chemical has a first order decay rate of 0.15/d. Find the volume of the CFSTR (in m³).
(a) Prove that for a first order decay reaction (k1= 2 days-1) taking place in reactors of identical size at steady state, it does not matter if you use a CMFR followed by a PFR or a PFR followed by a CMFR (i.e. show that the final treated effluent concentration, in mg/L, is approx. the same in each scenario). Assume the volume of each reactor is 15 L and the reactors in series will be used to treat a wastewater containing 5 mg/L of contaminant “C” at a flowrate of 10 L/day. (b) Does this remain true if a second order decay reaction was taking place? If not, which sequence of reactors is more efficient (i.e. removes more of the contaminant)? Assume the same reactor volumes, flow rate and contaminant concentration as in part (a), and k2 = 2 Lmg-1day-1 . You must show your derivation of the expression for a PFR with 2nd order decay.
