ABSTRACT:
A device for separation of constituents, separable in a filter, from a liquid medium, comprising a stack of a plurality of plate units (10), arranged one after the other, with filters (11) arranged therein. Along the filters there are arranged rotors (24) for scraping off coatings deposited on the filters. Each rotor is mounted on a separate shaft piece (22) arranged in each plate. The shaft pieces are connected to each other by means of connections which can be drawn apart in the stacking direction of the plate units. Defects in the device can be detected in a channel (20) which extends in the stacking direction of the plate units and which is common to liquid having passed through the filter. A defective plate unit can be shut off, while maintaining the separation device in operation, and be replaced without dismantling the entire device (FIG. 7).
