1.	Which material is disengaged in the disengagement zone?(a) Culture broth(b) Culture media(c) Bubbles(d) MicrobesI got this question in quiz.My query is from Bioreactor Configurations topic in portion Reactor Engineering of Bioprocess Engineering
Answer» Right option is (c) Bubbles For explanation: The sudden widening at the top of the REACTOR SLOWS the bubble velocity and thus disengages the bubbles from the liquid FLOW. Carbon-dioxide rich bubbles are thus prevented from entering the downcomer. The increase in area will also helps to stretch bubbles in foams, CAUSING the bubbles to burst. The AXIAL flow circulation caused by the draft tube also helps to reduce foaming.
