A filtering component for a filtering unit with backwashing, the filtering component being annular and comprising a filtering medium between an inner edge and an outer edge, and an internal face and an external face on either side of the filtering medium. The filtering component is adapted to be assembled against a first identical filtering component so that their facing respective internal faces define a space that is circumferentially compartmented by contacting respective ribs. One of the inner edge and the outer edge has passages communicating with each of the sectors on the internal face. The external face has a key for pairing the filtering component in a given position with respect to a second identical filtering component, such that the passages of the second identical filtering component are offset with respect to the passages of the filtering component.
A filtering component for a filtering unit with backwashing, the filtering component being annular and comprising an inner edge, an outer edge and a filtering medium extending between the inner edge and the outer edge, the filtering component having an internal face and an external face on either side of the filtering medium, wherein, on the internal face, ribs extending between the inner edge and the outer edge are circumferentially distributed to form sectors, wherein the filtering component is adapted to be assembled against a first identical filtering component so that their facing respective internal faces define a space that is circumferentially compartmented by the contacting respective ribs of said internal faces, wherein a first one of the inner edge and the outer edge has passages communicating with each of the sectors on the internal face, and wherein the external face has a key for pairing the filtering component in a given position with respect to a second identical filtering component, the key being arranged such that the passages of the second identical filtering component are offset with respect to the passages of the filtering component.
A filtering element for a filtering unit with backwashing, the filtering element being annular and comprising an inner edge, an outer edge and a filtering medium extending between the inner edge and the outer edge to define a pre-filter chamber, at least the pre-filter chamber being circumferentially compartmented in sectors, at least one of the inner edge and the outer edge having passages communicating with each of the sectors, wherein the filtering element further has a key for pairing the filtering element in a given position with respect to an identical filtering element, the key being arranged such that the passages of the identical filtering element are offset with respect to the passages of the filtering element.
A filtering assembly for a filtering unit with backwashing, comprising a sleeve and a plurality of filtering parts stacked with one another, wherein each filtering part has a filtering medium and a plurality of passages for conducting fluid to the filtering medium, the passages opening out on compartmented sectors, wherein the filtering parts are keyed with respect to the sleeve so that the passages of one of the filtering parts are offset with respect to the passages of an adjacent one of the filtering parts.
