Cake filtration research—a personal view

An outline of the directions and topics of future cake filtration research is presented. The proposed topics include the formulation of more accurate and efficient procedures of determining filter cake characteristics from experimental data, more complete analysis of cake formation and growth, the effect of accurate and non-intrusive measurements of the evolution of cake thickness histories. The selection is based on practical needs, intrinsic significance or both. The relationships between these proposed topics and some current and past research are also discussed.
