Problem
The rate of growth of Escherichia coli obeys Monod kinetics with μmax = 0.9 h-1 and Ks = 0.7 kg/m3. A CSTR is used to grow the bacteria at 1 kg/m3 with inlet substrate pollutant feed rate of 1 m3/h and [S]in = 100 kg/m3. If the cell yield is 0.7, calculate
(a) the reactor volume required for the maximum rate of production of E. coli?
(b) If the effluent from the reactor is fed to a series reactor, what is the volume of the second reactor if the desired pollutant concentration in the exit stream is 0.1 kg/m3?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
