3. To split the flow into reactors in parallel with the same residence
time does not have any impact on the final effluent concentra-
tion, as shown in cases (a), (b), and (d).
4. Note that all the effluent concentrations from the CFSTRs in
Example 4.22 exceed the cleanup level. These two examples
again illustrate that PFRs are more efficient than CFSTRs, pro-
vided that the influent concentrations, reaction-rate constant,
and the residence time are the same.
