ABSTRACT:
An electrokinetic cell for the separation of solid particles from an aqueous suspension thereof, the cell being equipped with an anode and cathode separated by a semi-permeable membrane impermeable to clay particles which divides the cell into anode and cathode compartments. Upon application of direct current to the anode and cathode, clay particles in a suspension fed to the anode compartment deposit electrophoretically on the anode. Water contained in the suspension and entrained in the deposit simultaneously migrates electrosomotically therefrom and through the membrane where it is collected in the cathode compartment and thereafter removed from the cell.
