Abstract

Surface sulfonated copolymer beads and glass beads of various size distributions were used to study the removal of liquid from a packed column of spherical beads under centrifugal force. At low forces, from 1 G to approximately 20 G, the volume of liquid retained corresponds to the free volume between the packed beads. The liquid level varies with force from about 20 to 400 G. It is shown that the liquid level is a function of the force applied and the size distribution of the beads in the column. At forces from approximately 400 to 1200 G the weight of the liquid on the sample remains constant.
