Abstract
An apparatus for dewatering aggregate solid substrates is disclosed which is comprised of a frame, two moving permeable belts, means mounted on the frame for guiding the movement of the belts, roller means mounted on the frame for positioning the belts such that the substrate is guided and compressed between them, means for contacting the substrate with a displacement fluid while it is compressed between the belts such that the fluid collects between the top belt and the roller means before permeating through the top belt and contacting the substrate, means for removing relatively pure water which is expressed by the fluid through the bottom belt, means for further compressing the substrate to remove excess displacement fluid, and means for removing the dewatered substrate from the apparatus.
