PROCESS FOR MANUFACTURING A STERILIZING FILTER
The present disclosure relates to a process for manufacturing a sterilizing filter comprising a plurality of hollow fiber membranes having a large inner diameter.
HOLLOW FIBER MEMBRANE MODULE
A hollow fiber membrane module includes a pressure vessel, a plurality of hollow fiber membrane elements arranged in series inside the pressure vessel, and a connector that connects the hollow fiber membrane elements to each other. Each of the hollow fiber membrane elements includes a plurality of hollow fiber membranes, and a double-core tube extending in a longitudinal direction of the plurality of hollow fiber membrane elements. The connector includes a first channel and a second channel that do not communicate with each other. Between the hollow fiber membrane elements, the outer channels of the hollow fiber membrane elements are connected to each other through the first channel, the inner channels of the hollow fiber membrane elements are connected to each other through the second channel, and hollow portions of the hollow fiber membranes communicate with the inner channels through the second channel.
METHOD FOR MANUFACTURING HOLLOW FIBER MEMBRANE MODULE, AND HOLLOW FIBER MEMBRANE MODULE
A method for manufacturing a hollow fiber membrane module, the hollow fiber membrane module including: a hollow fiber membrane bundle including a plurality of hollow fiber membranes; a housing configured to contain the hollow fiber membrane bundle; and a potting part in which a potting agent is added between an outer surface of the hollow fiber membranes and an inner surface of the housing at both end regions or at one end region of the hollow fiber membrane bundle, wherein the method including: providing a sheet-shaped spacer in a space between the hollow fiber membranes at the both end regions or at the one end region of the hollow fiber membrane bundle; and adding a potting agent between the outer surface of the hollow fiber membranes and the inner surface of the housing at the both end regions or at the one end region of the hollow fiber membrane bundle such that the provided spacer is embedded, wherein the potting agent includes resin, rubber, or elastomer, as a main ingredient, and wherein the spacer is a net, a non-woven fabric, a porous sheet, or a film.

CO2 CAPTURE AND UTILIZATION SYSTEM AND METHOD
A carbon dioxide (CO.sub.2) capture and utilization system captures CO.sub.2 from flue gas and utilizes the same to enhance algae or cyanobacteria growth. The system generally comprises a CO.sub.2 capture unit and a utilization unit that is in fluid communication with the CO.sub.2 capture unit. The CO.sub.2 capture unit includes a membrane CO.sub.2 absorber that captures CO.sub.2 from incoming flue gas to produce a CO.sub.2-rich solvent. The utilization unit processes the CO.sub.2-rich solvent to produce a product stream that includes CO.sub.2 and NH.sub.3 in a predetermined CO.sub.2:NH.sub.3 ratio. The product stream is delivered to a cultivation subsystem of the utilization of the unit including one or more species of algae or cyanobacteria. A method for capturing and utilizing CO.sub.2 is also provided herein.
Porous Composite Membrane for Solvent Extraction
An example porous composite membrane for solvent extraction is provided. The porous composite membrane includes a Janus membrane with a first side and a second side opposing the first side. The first side exhibits hydrophobic characteristics and the second side exhibits hydrophilic characteristics. At least one of the first side or the second side is sized to perform nondispersive membrane solvent extraction.
DIFFUSION DEVICE
The present disclosure relates to a diffusion device, such as a blood oxygenator or gas exchanger, and a process for its production. The diffusion device is used in the removal of carbon dioxide from blood.
Cartridges and systems for membrane-based therapies
A cartridge is provided for dialysis or other blood processing therapy. In the cartridge, fibers may be substantially uniformly distributed near a midplane, but near an end, in the inter fiber space, there may be void flow channels, which may cause fluid flow in the inter fiber space to transition within a short region to uniform flow with minimal stagnation zones. Void flow channels may be be radially oriented, introducing fluid from the outer circumference, or axially oriented, introducing fluid along the axial direction through passageways through the potting material. The fluid flow in the inter fiber space may be perpendicular to the fibers, or radial with respect to a cartridge longitudinal axis. The cartridge may have blood flow in the inter fiber space, and flow of dialysate or ultrafiltrate in the lumens of the fibers, or the opposite situation.
