Abstract: A method and apparatus for removing a fluid from a mixture of a fluid and a solid substance. The mixtue is poured onto the upper run of a moisture-permeable conveyor belt conveying the mixture along a trajectory. In the first portion of the trajectory, the fluid flows out of the mixture by a draining effect, whereas in the last portion of the trajectory an increasing pressure is exerted on the mixture by mechanical means, while a relative displacement of the solid particles is performed.

Abstract: The invention relates to a method and a device for separating liquids and solids from a mixture, in which the mixture is applied in the form of a layer to a movable, endless filter belt, which is supported from a subjacent suction box adapted to move parallel to the belt, in which box a subatmospheric pressure is intermittently produced, the liquid constituents of the mixture being drawn across the filter belt during the periods of subatmospheric pressure, while the filter belt and the suction box are in intimate contact with each other and do not move relatively to each other owing to the suction force, whereas at the restoration of the atmospheric pressure in the suction box a relative displacement of the filter belt and the suction box is carried out.
