  • Patent number: 11001508
    Abstract: A filter housing can be configured to receive a filter media to form a filter assembly. Water filter media housings can be adapted for filter-as-you-pour filtration in the context of container (e.g., pitcher) systems where filtering is achieved as the user pours water from the container. The filter housing can have a frame and an optional casing securable about the frame. A filter assembly can include a filter media within, connected to, or associated with a filter housing. The filter media can be securable in an at least partially curved configuration and/or within, connected to, or associated with the filter housing.

  • Patent number: 10981100
    Abstract: A filter module with a perforated inner tube (20) and a concentric, perforated outer tube (22), forming an interposed annular gap for a filter membrane (10) pleated into folds. The membrane folds (11, . . . ) are of different fold types with differing fold heights, extend from a respective fold edge (111, . . . ) resting against the outer tube towards the inner tube to the respective fold tip (114, . . . ) and are arranged along the circumference of the annular gap as groups of folds (11, . . . ) of different types. Each group has a mating fold (15) which extends from a mating fold edge (151) resting against the inner tube towards the outer tube to the mating fold tip (154). The height of the mating fold is no more than the difference between the width of the annular gap and the height of the fold type with the shortest height of the same group.

  • Patent number: 10946325
    Abstract: There is a need to reduce the amount of overlapping parts of a nonwoven fabric of a filter component to thereby lengthen the life of the filter component. This need is met by the filter component formed of a cylindrical nonwoven fabric having a center axis, and having a plurality of polygon-shaped cross-sections which are a same shape that are formed side-by-side at predetermined intervals along the center axis. Each side of each of the polygons is formed by a mountain fold part on a plane perpendicular to the center axis, and each vertex of one polygon is connected by a mountain fold part to each vertex of another polygon, respectively.

  • Patent number: 10478759
    Abstract: A filter element has a preferably multilayer structure of a pleated filter medium (3) with a plurality of individual filter pleats (5, 7). Due to an alternating sequence of filter pleats (5) with a first pleat height (h1) and filter pleats (7) with a second pleat height (h2), more effective filter surfaces are available than with filter pleats with a uniform pleat height. Upon throughflow by a fluid to be filtered, a lower surface load for the filter medium (30 and lower passage speed of the fluid are present during filtration. A static loading of the filter medium (3) during operation of the filter is then reduced. A hydraulic circuit has such a filter element (1).

    Abstract: A filter element that is provided with automatic air bleeding features to efficiently bleed air from a fuel filter module containing the filter element. The filter element has an upper end cap with one or two air vents. One of the vents provides a bypass for air through wet filter media through which air from the fuel supply may not be able to pass through easily. The inner air vent is located on the inside of a circle formed by attachment clips that attach the respective filter element to a removable cover. The inner air vent allows for air inside the filter module to be easily purged out via a drain hole on the fuel filter module, while providing resistance to fuel. The drain hole is provided on the filter module which is internally connected to the fuel outlet and therefore to the fuel tank.

  • Publication number: 20140183134
    Abstract: Described herein is a structure for a permeate spacer for use in spiral wound osmosis membrane elements, having at least two sets of parallel ribs, wherein the ribs in the first set are oriented at about a 90 degree angle to the ribs in the second set. The permeate spacer is used by sandwiching it inside a membrane envelope or leaf, and is particularly useful for non-pressure-driven processes, such as forward osmosis (FO) and pressure-reduced osmosis (PRO).

  • Patent number: 8757393
    Abstract: A replaceable filter has a filter housing with a cylindrical connecting end. A housing lid has a cylindrical counter connecting member matching the cylindrical connecting end. A filter closure system seal-tightly connects by form fit the cylindrical connecting end and the cylindrical counter connecting member when the connecting end is inserted or pushed onto the counter connecting member in an axial connecting direction and moved relative to the counter connecting member. An annular member is arranged coaxially relative to the connecting end and has a terminal edge area that is connected seal-tightly to the filter housing such that the annular member and the connecting end define a receptacle for the cylindrical counter connecting member. A sealing device is arranged in the receptacle and connected to the filter housing. The sealing device interacts with the counter connecting member.
