Question

Alternative reactor systems are being considered to reduce the reactant in a steady liquid flow from
an initial concentration of 100 mg/L to a final concentration of 20 mg/L. Assuming a first-order
reaction-rate constant of 0.80 day-1, calculate the hydraulic retention time required for each of the
following reactor systems:
1. One plug flow reactor.
2. One completely mixed reactor.

The volume of a CFSTR is 45 m' and average constant flow in the reactor is 300 m /d. The reactor flow regime was established by feeding continuously 6 g/L stock tracer solution in the influent line at a rate of 125 L per day. Determine the theoretical tracer concentration in the effluent at 3 and 10 h after the tracer injection. Plot the tracer profile as a function of (a) concentration versus t, and (b) C/Co versus t/0.
For an SBR process, the sludge takes 45 minutes to settle and the depth of liquid in the reactor is 40% of the depth of the reactor after draw-off to prevent disturbing the settled sludge. The draw-off period takes an additional 20 minutes after the settle face. An idle time of 10 minutes is to be allowed. What is the required volume of each of the tanks in 2-tank and 3-tank SBR systems to handle a flow of 55000 M cubed per day to provide a react time of 60 minutes?
