Abstract
An electroflocculation cell for the separation of clay particles from an aqueous suspension thereof, the cell being equipped with an anode and cathode separated by a first semipermeable membrane impermeable to clay particles which divides the cell into anode and cathode compartments. A second semipermeable membrane is provided in the anode compartment spaced from the anode and the first membrane. Upon application of a direct current to the anode and cathode, clay particles in a suspension fed to the area of the cell between the first and second membranes deposit electrophoretically on the second membrane. By avoiding contact of the clay deposit with the anode, contamination of the deposit by anode corrosion products is thereby avoided.
