Abstract
A method and an apparatus for washing a fiber pulp mixture, whereby water and, with it, ash and other particle-type impurities are removed from the fiber pulp mixture. The fiber pulp mixture is fed between two wires in a dewatering section so that water and ash are removed from the fiber pulp through both wires, after which the wires and the fiber pulp between them are led to run along a curved surface to remove any extra water by means of the tension of the wires and centrifugal force.
