METHOD OF DRAINING WATER FROM LOW-CONSISTENCY WATER-FIBRE SUSPENSIONS

摘要

A method of draining water from low-consistency water-fibre suspensions. In the method, the water-fibre suspension is fed to a filtering surface comprising holes. In the method, the rougher fibres are first separated from the water-fibre suspension and fed to the filtering surface to form a separate filtering layer and the water-fibre suspension is led to flow through said filtering layer formed by the rougher fibres.
