METHOD AND APPARATUS FOR DEHYDRATION OF SLUDGE Abstract of the Disclosure Sludge like sewage sludge is fed at the beginning of a path of travel of two endless belts of filter material. The sludge, carried between the two endless belts, is compressed and dehydrated between a drum which is supported in bearings with its periphery in contact with one of the endless belts and pressure belts which are trained around a plurality of rolls and brought into contact with the other of the endless belts. The pressure belts are composed of a multiplicity of narrow belts. Pressing by individual pressure belts is applied to the endless filter material belts at a suitable number of stages into which the path of the filter material belts is divided. Preferably, pressure is exerted on the sludge by a smaller number of pressure belts at early pressing stage and by a larger number of pressure belts at later pressing stages.
