You are being tasked to design a continuous bioreactor for growing bacterial cells. Your colleagues suggest three possible configurations as shown below: Scheme 2 FOFOO Scheme 1 Sin. Xin=0 F Sout V₂ V₂ Scheme 3 Sout In all three configurations the volumetric flowrate of the sterile medium F and the inlet substrate concentration Sin will be the same: F= 15 L/h and Sin= 10 g/L. In Scheme 1, the reactor volume is V₁-100 L, and in Schemes 2 and 3 the bioreactor volumes are V₂ = 0.5V₁. The microbial process follows the Monod kinetics with um = 0.2 h¹, Ks = 2 g/L, and Yx/s = 0.5 g/g. (a) (15 points) Calculate the substrate conversion for each bioreactor configuration. (b) (5 points) Which configuration would you recommend and why? You are being tasked to design a continuous bioreactor for growing bacterial cells.
