ABSTRACT In the treatment of a suspension of pulp fibre it is known to provide roller presses with a washing device. However, as there is no defined washing area within these devices the pulp fibre suspension becomes canalized, which results in poor washing and a tendency towards the formation of plugs. The present invention pertains to a method and an apparatus for the treatment of a pulp fibre suspension in which there is a definite washing zone, thus overcoming the drawbacks of the prior art.
