A new sampling device for measuring solids hold-up in a three-phase system

  • Published:
Biotechnology Techniques

Abstract

Measurement of solids hold-up in gas-liquid-solid systems was achieved by using a cylinder with a valve in each extremity, which allowed direct sampling inside the reactor causing minimal disturbances to the fluid flow. The method was developed and tested in a 60 L concentric draught tube airlift reactor. Validation of the method was done by means of an overall balance to the solid phase in the bioreactor.
