In embodiments of the invention, there is provided a dialyzer or filter comprising hollow fibers, in which blood flows on the exterior of the hollow fibers, and dialysate or filtrate may flow on the inside. The external surfaces of the hollow fibers may have properties of smoothness and hemocompatibility. The fiber bundle may have appropriate packing fraction and may have wavy fibers. Optimum shear rates and blood velocities are identified. Geometric features of the cartridge, such as pertaining to flow distribution of the blood, may be different for different ends of the cartridge. Air bleed and emboli traps may be provided. Lengthened service life may be achieved by combinations of these features, which may permit additional therapies and applications or better economics.

A cartridge for a water purifier has: a granular filter medium; an inner cylinder that supports the granular filter medium from inside, and does not allow the granular filter medium to pass through but allows water to pass through; an outer cylinder that supports the granular filter medium from outside, and does not allow the granular filter medium to pass through but allows water to pass through; a cap member that connects one end of the inner cylinder to one end of the outer cylinder, and that has an opening connected with an inner diameter side channel; an inner cylinder blocking member that blocks the other end of the inner cylinder; and an end portion adhesion material for adhering and fixing the inner cylinder blocking member and the outer cylinder, wherein the inner cylinder blocking member, the outer cylinder, and the end portion adhesion material are arranged so as to integrally block the granular filter medium.

Disclosed herein is a hollow fiber membrane module provided with a hollow fiber membrane bundle, a case in which the hollow fiber membrane bundle is contained, a fixation part which affixes the hollow fiber membrane bundle within the case and divides the space inside the case into a first space that is outside the hollow fiber membranes and a second space that is in communication with the insides of the hollow fiber membranes, and a partition plate which divides the first space into a first region and a second region.

A sterile solution product bag includes sterilization grade filter integrated directly into the product bag such that microbial and particulate matter filtration can be performed using the filter directly at the point of fill. The filter can include a hollow fiber filter membrane contained in a stem connected to a bladder of the product bag.

A filter module (10) including: a housing (12) extending between an opposing first (14) and second end (16) and defining an inner chamber (18), a plurality of hollow fiber membranes (20) located within the inner chamber, a tubesheet (26) including the ends (24) of the hollow fibers encased but open within a block of potting material, an end cap (30) secured to the end of the housing and including: a permeate fluid outlet (32) in fluid communication with the ends of the hollow fibers, and a concentrate fluid outlet (34) in fluid communication with the inner chamber, wherein the permeate and concentrate fluid outlets are axially aligned, and a concentrate distributor (36) including: an annular ring (38) located adjacent to the second end of the housing, at least one aperture (40) in fluid communication with the inner chamber, and an annular concentrate passageway (42) extending from the aperture and concentrically about the permeate tubesheet to the concentrate fluid outlet of the permeate end cap.

A membrane filter module configured to treat a liquid contained in a tank at an ambient pressure. The module may have a header, with a bundle containing a plurality of substantially vertical hollow fiber membranes, wherein a lower end of each hollow fiber membrane is fixed in the header. The module may also have a gasification device adapted to periodically generate a gaseous bubble and configured to release the gaseous bubble within the bundle. The module may further have an enclosure that substantially surrounds the bundle that extends from a lower region to an upper region of the membrane bundle, wherein the enclosure is configured to retain the liquid introduced into the enclosure such that the liquid surrounds the membrane bundle. The gaseous bubble has a cross-sectional area that corresponds with a cross-sectional area of the enclosure, such that the cross-sectional area of the gaseous bubble occupies substantially the entire cross-sectional area of the enclosure as it flows along the bundle.

A water filter cartridge is reduced in fluctuation in filtration flow rate or in filtration performance due to activated carbon, and can exhibit stable performance even at the time of large scale production; and a water purifier is equipped with the water filter cartridge.
