Abstract

In this work, bubble size distribution generated by six-blade impeller (6CB) was compared with Rushton Turbine(6RT)in a 40 cm diameter cylindrical tank for gas-liquid and gas-liquid-solid systems.Bubbles were drawn out from the tanks using a suction pump and captured by digital camera when the bubble passed through a specially built cylindrical perspex tube. The Sauter mean diameter, d32 and distribution curves were compared at 5L/min aeration rate and 60,80,and 100 rpm for two(0% inert solid) and three phase systems (addition of 2%wt inert solid). The investigation showed that at 60 rpm, d32 values that 6CB. Addition of solid 2%wt inert solid was found to decrease the d32 values (compared to gas-liquid system) but became almost similar and bi-modal distribution was also observed for both the impellers.
