ABSTRACT:
A filter to concentrating fiber suspension of the type having annular filter discs (2) which rotate about a collection trough (13) for dewatered fibers. Each filter disc comprises two mutually spaced filter elements (3) which, together with an annular wall (4) radially inwardly terminating the disc, define a filtrate chamber (5) inside the disc. The filtrate chamber (5) communicates radially outwardly with its surroundings. The suspension container (1) of the filter is inwardly provided under the suspension surface with an arcuate duct (15) for each disc, this duct being in communication with the filtrate outlet (17) of the container. Thee is communication between each disc (2) and associated duct (15) such that the filtrate can be transferred from a filtrate chamber to the respective duct (15).
