Just-suspension conditions were studied in a dished base baffied cylindrical tank with internal diameter, T = 155 mm using two variables of impeller-to-tank geometry, D = 0.3T and 0.5T. The performance of the alternative geometries was studied using a conventional down-pumping 45 degrees four pitched blade turbine (4PBT) impeller in comparison to the novel SATAKE SUPERMIX (R) HR100 and HS604 impellers. The slurry comprised of 18.0, 75.3 and 195.5 mu m PMMA particles in concentrations ranging from 5-40% by weight. The performance of solid suspension was assessed in a dished base tank, which was found to be not as effcient as the flat base tank when used with the D = 0.5T impellers. However, it is interesting to note that, when used with a suitable impeller, namely the HS604 impeller, the dished base tank was more superior to the flat base tank. This indicates that impeller-to-tank geometry is critical in determining the effciency of solid suspension. Additionally, solid suspension performance in a dished base tank was markedly enhanced with D = 0.3T impellers by approximately 60 to 80% reduction in the specific energy at just suspension (epsilon(js)) compared with D = 0.5T, resulting from the fluid flow pattern generated inside the stirred tank. This suggests that the dished base tank is not a poor option for solid suspension if it is used with the right impeller geometry.
