Abstract

The solid-liquid mass transfer coefficient k_L of EGSTAR agitator, which has been practically used as a bioreactor, was measured and compared with the coefficients of some conventional impellers. Under operation conditions above the critical rotational speed for complete suspension, the solid-liquid mass transfer coefficient depends only on the power consumption per unit volume P_v regardless of the impeller geometries. The power consumption of the liquid circulation type impellers, propeller and pfaudler, for the complete suspension was lower than that of the high shear type impellers. The Maxblend impeller has the largest k_L among the impellers used at low rotational speed. The EGSTAR agitator, in which solid particles are packed, has larger k_L than the other impellers at low P_v.
