Compressible cake filtration

The formation of a compressible kaolin filter cake has been examined using an electrical conductivity technique that continuously monitors the local solids concentration with height and time during filtration. The relative importance of liquid drag, solids weight and velocity inside a filter cake during the cake forming process were studied, and their effect on the modelling approach of Tiller and Shirato considered. It is concluded that a more accurate representation of the cake concentration profile would result from an incremental simulation of the solid deposition process.
