A filter medium includes a plurality of layers each including an undulating strip of solidified material.

Screening members, screening assemblies, methods for fabricating screening members and assemblies and methods for screening materials are provided for vibratory screening machines that incorporate the use of injection molded materials. Use of injection molded screen elements provide, inter alia, for: varying screening surface configurations; fast and relatively simple screen assembly fabrication; and a combination of outstanding screen assembly mechanical and electrical properties, including toughness, wear and chemical resistance. Embodiments of the present invention use a thermoplastic injection molded material.

A filtration device (10A, 10B, 10C) comprising one or more filtration media (20) secured by one or more activatable adhesive layers (22). A method of forming a filtration device, including: (a) forming the one or more adhesive layers into a desired shape; (b) activating the one or more adhesive layers; (c) securing the one or more filtration media to the one or more adhesive layers; and (d) curing the one or more adhesive layers.

A method for manufacturing a filter includes providing a computer-readable three-dimensional model of the filter, the three-dimensional model being configured to be converted into a plurality of slices that each define a cross-sectional layer of the filter, and successively forming each layer of the filter by additive manufacturing.

A layered porous film with a fluidic path through orthogonally oriented ribbed layers of varying size and spacing for the filtering or separation of particles or compounds. Any number of additional layers and materials may be added to modify the flow characteristics through the film.

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).

A blood treatment filter includes a housing having a first resin sheet and a second resin sheet, a filter member disposed in the housing, a peripheral edge molded body formed on a peripheral edge portion of the filter member and having an inner peripheral portion joined to an outer peripheral end edge of a filtering material, and a connection sheet extending outward from the peripheral edge molded body and connected to the housing.
