A spiral wound-type separation membrane module and a method for manufacturing the same are provided. The spiral wound-type separation membrane module according to an exemplary embodiment of the present invention is implemented by including an outlet pipe; a filter assembly wound in a spiral wound on the outlet pipe; and an adhesion portion in which part or all of a heat-adhesive yarn wound to surround the outer surface of the filter assembly in the longitudinal direction of the outlet pipe is melted and fixed to the filter assembly. According to the above, the spiral wound-type separation membrane module and the method for manufacturing the same can significantly reduce the defect rate and process time and simultaneously exhibit an eco-friendly effect during disposal after use.

In one aspect, a tubular membrane assembly is provided for a heat exchanger. The tubular membrane assembly includes a header having a header body, a tubular membrane, and a fitting connecting the tubular membrane to the header body. The fitting is configured to form a fluid tight connection between the fitting and the tubular membrane. The tubular membrane assembly further includes potting of the header keeping the tubular membrane connected to the fitting.

A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.

A potable water filter for an aircraft galley plumbing system is disclosed. In embodiments, the filter includes a body attachable to a mount via a central threaded attachment stud. The stud is surrounded by a filter mount chamber and encloses a central flow channel allowing outflow from the filter body to an outlet port. Potable water enters the mount through an inlet port; an annular “puck” inlet valve extends around the attachment stud, sealing off the filter mount chamber when the filter body is absent and, when the filter body is screwed onto the attachment stud, providing for water flow throughout the filter mount chamber. The filter body houses a solid block of sintered carbon with a hollow core. Water enters the filter chamber via bypass slots in the base of the filter body and flows around and through the carbon filter before flowing down to the outlet port.

Disclosed is a hollow fiber filter arrangement and a bioreactor system comprising such a hollow fiber filter arrangement. The hollow fiber filter arrangement comprising: an inlet for receiving a sample to be filtered in the hollow fiber filter arrangement; an outlet for delivering of the filtered sample out from the hollow fiber filter arrangement; a bundle of elongate hollow fibers connected at a first end to the inlet and connected at an opposite second end to the outlet; and an outer housing enclosing the bundle, wherein a filtrate/waste collection space is provided between the outer housing and the at least one elongated hollow fiber, and wherein the outer housing is made from a flexible material.

A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.

A cartridge for non-cryogenically separating a gas into components includes a plurality of hollow polymeric fibers, the fibers being anchored by a pair of tubesheets, each tubesheet being adjacent to a head, the tubesheet and head being joined by a clamshell retainer. The cartridge does not have a core tube. The fibers are enclosed within a sleeve, the sleeve being sufficiently thin so as to be a non-structural element. The cartridge may be inserted within a larger pressure vessel. The cartridge of the present invention can accommodate more fibers than comparable cartridges of the prior art, and therefore has greater throughput.

A membrane humidifier for a fuel cell includes a hollow fiber membrane cartridge including a cartridge housing which is formed as a hollow having openings facing opposite sides of the cartridge housing in the longitudinal direction thereof and which has a side wall having a plurality of vent holes, a hollow fiber membrane inserted into an interior of the cartridge housing, and a resin layer filling an inner space of opposite sides of the cartridge housing in the longitudinal direction thereof, a membrane humidifier housing in which the hollow fiber membrane cartridge is formed, and a bulkhead formed in an interior of the membrane humidifier housing, wherein the bulkhead has mounting holes into which ends of the cartridge housing in the longitudinal direction thereof are inserted.

The present invention relates to a fuel cell membrane humidifier capable improving humidifying efficiency by controlling the flow direction of fluid, and the fuel cell membrane humidifier according to an embodiment of the present invention comprises: a hollow fiber membrane module for accommodating a hollow fiber membrane in which a first fluid and a second fluid perform moisture exchange while the first fluid flows therein and the second fluid flows on the outside thereof; and a housing part constituting the appearance of the membrane purifier, wherein a fluid guide part for uniformly guiding the flow of fluid is formed between the hollow fiber membrane and the housing part.

A tube unit includes multiple tubes and bundling portions that bundle end portions of respective tubes at opposite ends of the tubes. At least one of the end portions of respective tubes has a tube wall portion that tubularly extends in an extension direction of the tubes and also has a protrusion protruding radially outward from the tube wall portion.
