The present disclosure relates to an apparatus used in the production of a sterilizing filter for dead-end filtration of medical liquids which comprises a plurality of microporous hollow fiber membranes having a large inner diameter, and to a process for operating the apparatus.

The present disclosure relates to a process for manufacturing a sterilizing filter comprising a plurality of hollow fiber membranes having a large inner diameter.

An emitter apparatus is mounted on a marine structure powered by wind or marine hydrokinetic energy to disperse a carbon dioxide sorbent such as sodium hydroxide. The sorbent can be generated by reverse osmosis of seawater with electrolysis of the brine, or delivered from an external supply. Suitable marine structures include offshore wind turbines, marine hydrokinetic generators, offshore oil platforms, merchant vessels, and other fixed and mobile structures. Effective capture is made by dispersing a fine mist or fog of aqueous sorbent from nozzles with a particle size from a nozzle of less than 100 microns. The sorbent reacts with atmospheric carbon dioxide forming carbonates and bicarbonates, which drift and fall to the ocean surface, reducing surface acidity and capturing additional atmospheric carbon dioxide via absorption at the local ocean surface. The resulting carbonates sink to the ocean floor and are there sequestered.

A cap removal device is adapted to remove end caps from water pump devices. The cap removal device has a cap remover that is adapted to be secured to the end caps of pressure vessels. The cap removal device further has a honed tube that is adapted to stabilize the cap removal device and the end cap during removal of the end cap thereby preventing cross-threading. The cap removal device also has a puller handle that is adapted to make removal of the end cap more efficient.

An automated modular filtration system, particularly for low volume tangential flow filtration processes, comprises a plurality of filtration modules formed as separate assemblies and at least one control unit for jointly controlling filtration processes of individual filtration units. Each filtration module contains at least one individual filtration unit for executing a filtration process independent of the other filtration units, first input ports for receiving a first type of fluids, second input ports for receiving a second type of fluids, and exit ports for outputting unused system fluids. First type fluids are process fluids are specific to the filtration processes executed in individual filtration units. Second type fluids are system fluids not specific to filtration processes executed in the individual filtration units. The second input and exit ports establish inter-module connections so system fluids can be forwarded from one filtration module to an adjacent filtration module of the filtration system.

A filtration system can include a loading member configured to receive a plurality of filtration members which can be sequentially moved from a non-active position in which a respective one of the plurality of filtration members is not in fluid communication with a sample flow path of the cell removal system, to an active position in which the respective filtration member is in fluid communication with the sample flow path, and to a discarded position in which the respective filtration member has been removed from fluid communication with the sample flow path.

A water purification filter element is provided. The water purification filter element may include a filter bottle, a filter material, an end cover, and a water self-stopping and passing structure.

The present invention relates to a cartridge of a fuel cell humidifier and the fuel cell humidifier, the cartridge comprising: an inner case to be inserted into a middle case of the fuel cell humidifier for humidifying dry gas supplied from the outside using wet gas discharged from a fuel cell stack; a plurality of hollow-fiber membranes accommodated inside the inner case; a first potting part which is coupled to the inner case and which fixes one side of each of the hollow-fiber membranes; a second potting part which is coupled to the the inner case and which fixes the other sides of the hollow-fiber membranes; and a link member for connecting the inner case to the middle case so that the middle case and the inner case are linked so as to move according to the pressure of the wet gas positioned inside the middle case.

The present disclosure relates to devices and processes for the production of hollow fiber membrane bundles. The bundles are used for the manufacture of filtration and/or diffusion devices, e.g., capillary dialyzers.

A flat-plate filter for water treatment and a flat-plate filter module comprising the same are provided. The flat-plate filter for water treatment according to an embodiment of the present invention comprises: a piece-shaped filtration member comprising a first support and a membrane formed on both sides of the first support; and a support frame fitted in and coupled to the edge of the filtration member so as to support the filtration member, and having a flow path through which filtered water introduced from at least one surface of the filtration member flows, wherein a part of the filtration member is disposed in the flow path or at the edge of the flow path such that the first support is exposed.
