The thickener contribution to the film thickness quantified as \(\Delta h(\% )\) was found to be a function of the thickener concentration and grease particle dimensions obtained using AFM. The degree of film enhancement was found to be proportional to the ratio of the thickener concentration to the average volume of the individual thickener

A rate limiting layer is identified and is used as the basis for the calculations. This layer corresponds to the layer in the sedimentation set up that has the lowest capacity for the passage of the solid particles (Foust, 1980) and thus requires the largest area. The volume required for the compression zone in the continuous thickener is
