Abstract
The present study in solid-liquid contactors, an attempt has been made to calculate the minimum/critical impeller speed required for complet e suspension of solids. A new correlation, involving Reynolds number, modified Froude number, along with the agitation characteristics is pr oposed. The effect of impeller geometry as well as impeller clearance are clearly established for 6-blade (flat) turbine agitated contactors .
