A harmful industrial organic compound, A, found in waste water, is transformed using an enzyme into a harmless product. Laboratory tests using a specific quantity of the enzyme in a mixed flow reactor give the following data:

Here is the residence time in minutes and and are the inlet and outlet concentration of A in mmol/.

This Demonstration computes the reactor volume (expressed in ) needed to treat of this waste water for in order to achieve a user-specified value of the conversion . Two types of reactor are considered: PFR (plug flow reactor) and CSTR (continuous stirred-tank reactor). The reactor residence time, in minutes, is equal to the shaded area shown in the figure.

For a PFR:

For a CSTR:
