A screening or filtration device for multi-phase mixtures, particularly liquids containing fibers, includes a casing with at least one feed pipe, at least one filtrate discharge pipe, at least one retentate discharge pipe, and at least one filter or screen through which the filtrate flows. The filter or screen being formed at least by an essentially rigid top surface of an at least essentially circular filter disc with hollow interior that can be rotated round an essentially central axis, where the interior of the disc is connected to the filtrate discharge pipe. The device also comprising at least one structural element adjacent to the filter or screen, where guiding and drive facilities are also provided that cause this structural element and the filter disc to describe movement relative to one another parallel to the level of the filter disc.
