The filter device (1) is especially used for mechanical cleansing of waste water and for water treatment. It is rotationally arranged in a container (2) and surrounded by the liquid to be filtered The filter device (1) comprises several filter elements (4) which arc arranged at a distance from each other, form segment-shaped filter modules (3) and are assembled to form a rotary filter. The individual filter elements (4) consist of filter plates which are used to divert the filtrate and which are provided with filters on both sides. The aim of the invention is to prevent solids from adhering to the filters during the filtering process. This is achieved by providing the rotary filter with a hollow area (14) that is connected to the container (2) via a suction inlet and which is scaled by means of a carrier plate (6) for the filter segments, and also by making the hollow area (14) cooperate with a now member. A pump blade wheel is used as a flow member. Preferably, the pump blade wheel (15) is driven via the rotary filter.
A filter device (1) for the clarification of contaminated liquids, in particular of sewage, consisting of a plurality of disk-shaped filter elements (4) which are spaced apart from one another and which are combined into circular or polygonal filter modules (3) and are arranged rotatably about a horizontal axis in a vessel (2) containing the unclarified liquid, the filtrate being capable of being discharged via the individual filter modules (3), characterized in that the filter modules (3) form centrally a cavity (14) which on one side is closed by means of a carrying disk (6) and on the other side is connected to the vessel (2) via a suction-intake orifice (12), and in that the cavity (14) is connected operatively to a flow member in such a way that, via the suction-intake orifice (12), a flow can be generated in the unclarified liquid between the spaced-apart filter elements (4) and avoids an adhesion of solids to the filter elements.
