ABSTRACT:
A method for removing liquid from a mixture of liquid and solid matter wherein the mixture is led over one or more casings by a conveyor belt which is pervious to liquid. In use a sub-atmospheric pressure is generated in the casings during a first period, in which the casing(s) and the conveyor belt are stationary with respect to each other, while at the same time a pressure is exerted on the mixture by one or more rollers. During a period following the first period, a relative movement takes place between the conveyor belt and the casing(s), while during this period no sub-atmospheric pressure is exerted in the casings and no compressive force is exerted on the mixture by the rollers.
