Abstract
There is provided an apparatus for the filtration of fluid media, in particular for the pre-screening of media, that has a primary pack of hollow discs, which are arranged parallel to each other at regular distances to each other, the walls of which are made of a sieve material. The apparatus also has a primary, hollow shaft, which penetrates and is fixed to the hollow discs, connecting its interior to the cavities of the discs, and is fitted with a drive. Also included is a secondary pack of discs, which are arranged similarly to the hollow discs of the primary pack. There is a secondary shaft that is arranged similarly to the primary shaft. The two packs with their respective shafts are designed and arranged in such a way that the discs of one pack protrude into the spaces between neighboring discs of the other pack. There is a container that encloses the packs and the shafts. The container has an inlet for the medium to be treated, as well as an outlet for the retentate. Each of the hollow shafts has an outlet for the filtrate.
