The effect of the type of impeller, particle size and shape, solids concentration, impeller submergence, and baffle configuration on the minimum draw down speed (Njd) and power input (Pjd) are investigated in this study. It was found that in baffled tanks where the formation of a large surface vortex was suppressed or reduced, the intensity of turbulence and mean circulation velocity of the liquid were responsible for solids drawdown and distribution in the tank. The position of the impeller relative to the liquid surface and the pumping mode of the pitched blade impeller (PBT) were found to be the controlling parameters. Based on the knowledge from the different experiments performed, a new configuration is proposed and studied. Better distribution of the particles and reduction of the rotational speed, Njd, and power requirement, Pjd, for solids drawdown relative to conventional baffle configurations was obtained. CFD simulations were carried out to obtain a better understanding and interpretation of the flow patterns and drawdown mechanisms for the different baffle configurations.
