ABSTRACT:
An apparatus and method for removing liquid from liquid bearing material are provided, the apparatus comprising a pair of electrodes having portions thereof disposed adjacent each other and defining an inlet to the adjacent portions and an outlet from the adjacent portions, structure for feeding the liquid bearing material into the inlet, structure for moving the liquid bearing material from the inlet to the outlet so that sections of the material serially move from the inlet to the outlet while being disposed between the adjacent portions, and a unit for creating a voltage between the pair of electrodes so as to create an electrostatic field arrangement between the adjacent portions of the pair of electrodes for acting through the material that is disposed therebetween to remove liquid from that material, the unit providing different voltages between different parts of the pair of electrodes so that different intensities of the electrostatic field arrangement serially act through each section of the material as each section of material moves from the inlet to the outlet.
