Abstract

A method of draining water from low-consistency water-fiber suspensions, in which the water-fiber suspension is fed to a filtering surface comprising holes. The rougher fibers are first separated from the water-fiber suspension and fed to the filtering surface to form a separate filtering layer and the water-fiber suspension is led to flow through the filtering layer formed by the rougher fibers.
