In the case of a specific auto catalytic reaction, we want to convert wastewater

with a flow rate of $0\mathrm{.}1\frac{m^3}{m}in$ and initial concentration $C_{A0}=10$mmo$\frac{l}{m^3}$ by $90\%$

using an enzyme called A$.$ Design the optimal reactor under the conditions given

below. $($Hint: reactor volume $)$

When installing one MFR$,$ find the size of the reactor to obtain a conversion

rate of $90\%.$

If a separator is installed at the end of the reactor to separate the unconverted

reactants and feed them back into the reactor, find the type of reactor and the

volume of the reactor required to obtain the minimum volume.
