摘要： A filter press type compressive and electroosmotic dehydrator comprises first and second press plates 20, 22 which can be brought into face-to-face abutment around a pair of filter cloths 32. The face of each press plate is recessed 42, 142, the recess 42 of one being lined with an electrically insulating flexible diaphragm 46 containing an embedded metal core plate 68 connected to one pole of a DC power source. Conductors 70 project from the core plate through the diaphragm and support a plurality of divided flush carbon electrode plates 76. The recess 142 of the other press plate contains an electrode plate 176 connected to the other pole of the DC power source. The divided electrode plates 76 have the advantage over a single electrode plate that they are subject to more even pressures and are less liable to break, and that the electrical pathways to the electrodes are shorter and equalized.
