Instabilities when using a Standard (T/3) Rushton Turbine for Stirring as Foam Disruption (SAFD)

Abstract:

The concept of using the upper stirrer for foam disruption in a bioreactor agitated by multiple impellers has recently been published by Hoeks et al. (1997). This concept, stirring as foam disruption (SAFD), was shown by them to be effective with a range of impellers. However, the commonly used (so-called) standard Rushton turbine of one-third the fermenter diameter was not included. This paper fills that important gap. By measuring the foam height, the holdup, the power draw and the velociti...
