Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).

A filter press device includes a supporting frame and elongated side rails disposed parallel and horizontally on the supporting frame. A following head assembly is disposed on an end portion of the supporting frame, and a following head assembly is movably disposed on another end portion of the supporting frame. The elongated side rails support a combination of filter plates of varying sizes through one or more adapters. An adapter plate interposes between adjacent filter plates of different sizes, providing fluidic communication between the different sized filter plates.

Filter disk segments, methods of use, and filter devices including the filter disk segments are disclosed.

A filtering unit includes a filtering component having a pre-filter chamber circumferentially compartmented in sectors, a filtering medium and a post-filtering chamber, a divider arranged coaxially with the filtering component and having distinct distribution columns, a cover and a rotary backwashing distributor having a shutter provided with a discharge opening. The rotary backwashing distributor is mounted to rotate so that the discharge opening is periodically and selectively put into communication with each distribution column. Each distribution column periodically and selectively establishes communication between the discharge opening and respective ones of the sectors. The filtering unit further includes a dividing plate arranged between the cover and the rotary backwashing distributor, the dividing plate being detachably secured with respect to the cover and having apertures opening into the distribution columns. The shutter abuts the dividing plate at least around the discharge opening.

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.

A filter element has: a carrier element permeable to fluid and having a support surface, the support surface having a surface area increasing contour; and a filter medium deposited onto the support surface of the carrier element forming a filter layer adapted to the surface area increasing contour.
