Abstract: The invention relates to an apparatus (1, 1?) for filtering a fluid, in particular a Bernoulli filtering apparatus (1, 1?), comprising: a housing (3, 3?), a plurality of filter elements (55), arranged in the housing (3, 3?), for filtering the fluid, an inlet (5) for admitting fluid to be filtered into the housing (3, 3?), and an outlet (7) for discharging the filtered fluid from the housing (3, 3?). The invention solves the stated problem by providing the housing (3, 3?) with a plurality of housing segments (23) which can be connected to adjacent housing segments (23), and by a filter element (55) being arranged at least partially inside each housing segment (23), and by the housing segments (23) and filter elements (55) together forming a modularly assembled filter module (9).

Abstract: A filter apparatus and method for filtering a liquid. The filter apparatus comprises a housing that has at least one inlet for admission of the liquid to be filtered and at least one outlet for discharge of the filtered liquid. The apparatus further comprises at least two substantially cylindrical filter elements that can be fitted into the housing and which have a plurality of openings through which the liquid can flow to filter particles out of the liquid, and at least one filter cleaning element that can be introduced into a respective filter element in a region of an inner surface of the filter element to increase a flow speed of the liquid to be filtered so that substances in the filter element are flushed away. The filter elements are further connected in a parallel arrangement in the filter apparatus.
