The reaction A --> B --> C has the rate equations. rA = 0.4 CA, rB = 0.3 CB - 0.4 CC Three tanks of different sizes are available. At the desired production rate, the residence times of 5 min, 10 min and 15 min, are maintained in the successive stages of the CSTR battery. The feed concentrations are CAo = 0.9; CBo = 1.2 and CCo = 0. Find the concentration of B in the effluent from each tank.

What will be the steady-state effluent BOD concentration for a CSTR (complete mix reactor with flows in and out, and no recycle) treating a wastewater with an initial BOD of 200 mg/L. The influent flow rate is 100 liters/day, and the reactor volume is 120 liters. Assume first order kinetics with a biodegradation rate constant of 0.5 day! Use the space provided below to show your calculations. mg/L Effluent BOD concentration

In a CSTR, reaction A→B occurs with rate constant kmol/s. The feed flow rate is Fi liter/s and the product flow rate is F liter/s. F is fixed (a pump is being used to maintain a constant product flow rate), whereas Fi is subject to changes. Therefore, the volume of solution in the reactor V is not necessarily constant. The concentration of A in the feed and product stream are CAi mol/liter and CA mol/liter, respectively. (a) (40 marks) derive...
