The present invention relates to a filtering panel (100) for a disk filter and a disk filter for water purification, comprising a metal filter cloth (16, 116) such as a stainless steel filter cloth, pre-tensioned in both warp and weft directions and fastened to a frame (10, 110) comprising a peripheral portion (11, 111), which is integral with an inner grillwork (12) and which divides the inner area of the peripheral portion (11, 111) into fields (15, 115). The frame (10, 110) comprises a plastic material reinforced with glass fibers or carbon fibres such as polypropylene loaded with fibreglass in an amount of at least 20 weight percent. Each field of the grillwork (12, 112) has an area not exceeding 10% of the inner area of the peripheral portion (11, 111). The pre-tensioning of the filter cloth (16, 116) in both directions is from at least 20% of the yield stress of the cloth (16, 116). Further the present invention relates to a disk filter comprising said filtering panels (100) and method of making said filtering panel (100).

The invention proposes a rotary filter intended for liquid/solid separation of a suspension, comprising a trough, a spraying device, and at least one disk which is non-rotatably connected to a main shaft, characterized in that: each disk comprises a first series of at least one filter sector which is separated from a second series of at least one filter sector by means of two non-filtering zones, the main shaft comprises a first pipe which communicates with the first series of at least one filter sector of each disk, and a second pipe which communicates with the second series of at least one filter sector of each disk, said rotary filter comprises comb teeth.

The invention also proposes a filtration method.

A filter for filtering liquid, comprising: a cylindrical housing; and a multiplicity of discs positioned perpendicularly to a height of the cylindrical housing, each of the multiplicity of discs comprised of a first number of cassettes, wherein each cassette is shaped as a truncated sector having a wide end and a narrow end, the cassettes arranged such that a perimeter of the disc is formed by the wide end of the first number of cassettes, and wherein each of the first number of cassettes is connected to a housing at its wide end, and each cassette having an opening along the wide end, wherein during filtration, liquid being filtered flows over the multiplicity of discs towards the perimeter of the multiplicity of discs.

The invention relates to a disc shaped filter element for filtering a liquid such as a polymer. The filter element comprising—a hub, said hub defining a central opening therethrough, —an upper filter medium and a lower filter medium, said upper filter medium and said lower filter medium extending radially outwards from said hub. The upper filter medium and the lower filter medium comprise a layered structure comprising a first layer and a second layer. The first layer comprises a non-sintered metal fiber fleece and the second layer comprises a layer of non-sintered metal powder particles. The first layer and the second layer are sintered together.
