Packed Bed Bioreactor vs. Batch Bioreactor


A waste water stream containing soluble contaminants species at 30 g/L is to be treated using bacteria immobilized in porous beads. The kinetics of contaminant conversion by this immobilized culture is subjected to inhibition by contaminant according to

Where rm = 32.8 g contaminant consumed/L of liquid h, Ks = 0.24 g/L and Kt = 40 g/L while the effects of external mass transfer limitations on contamination transport are negligible, we know that mass transfer limitations will present within the pores of the beads.

Suppose we will be required to achieve 95% contaminant conversion in this treatment process. State whether it is possible to operate with the same residence time and produce the same (95%) contamination conversion in each reactor for the following cases. provide a quantitative justification for each response.

Chemostat Vs. batch bioreactor


This question belongs to bioreactors in biotechnology and discusses about 95% contaminant conversion in a treatment process in bioreactors and to state whether it is possible to operate with the same residence time.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
