Abstract: In some embodiments thereof, the present invention describes TFF (Tangential Flow Filtration) filtration devices that utilize tubular membranes for the separation of cells and particles. These devices encompass several innovative features, including the use of membrane tubes with either circular or non-circular cross-sections. These tubes are closely surrounded by both tube housing and filter housing to regulate the pressure of the liquid exiting the filter housing. Additionally, the membrane tubes may feature internal cores within their lumens and/or structures along their inner walls. These internal features serve to regulate flow patterns and pressures within the tubes. One notable aspect of this invention is the inclusion of features on the tube housing or tube core that effectively regulate pressure resistance and feed flow patterns. These features lead to a reduction in the required recirculation rate and contribute to improved transmembrane pressure profiles, making these membrane filters highly effective for cell retention in cell culture and other applications. The patent also introduces various filter designs that incorporate tubular membranes into TFF filtration devices to achieve multiple goals, including a more consistent TMP (Transmembrane Pressure) profile for efficient separation, reduced recirculation rates to generate adequate shear rates, higher packing densities of membrane surface areas within the same filter design, and enhanced manufacturability and recyclability of the filters. Overall, this invention represents a significant advancement in the field of TFF filtration, offering innovative solutions for a wide range of applications in the separation of cells and particles.

Abstract: The present disclosure relates to a fuel cell membrane humidifier in which the discharge performance of condensate generated in a humidification module is improved. The disclosed fuel cell membrane humidifier includes a humidification module configured to humidify air supplied from an outside with moisture in off-gas discharged from a fuel cell stack, and caps respectively coupled to both ends of the humidification module. The humidification module includes a mid-case in which an off-gas inlet through which the off-gas is introduced and an off-gas outlet through which the off-gas is discharged are formed. The off-gas outlet is formed on a bottom surface side of the mid-case and configured to discharge condensate generated in the humidification module to the outside.

Abstract: A filter device includes an inlet manifold, an outlet manifold and membrane filter units. Each membrane filter unit has an inlet opening for a fluid flow to be processed, a first outlet opening for a retentate portion of the fluid flow, and a second outlet opening for a remaining portion of the fluid flow. Each inlet opening is fluidly connected to the inlet manifold, and each first outlet opening is fluidly connected to the outlet manifold. The two membrane filter units are staggered and are not axially aligned with respect to each other. One of the membrane filter units is fluidly connected to the inlet manifold and to the outlet manifold via a first set of conduits, and the other membrane filter unit is fluidly connected to the inlet manifold and to the outlet manifold via a second set of conduits.

Abstract: A hollow fiber membrane bundle useful for manufacturing a wide variety of hollow fiber membrane modules having different flow configurations includes hollow fiber membranes arranged around a porous support tube, a cured resin tubesheet formed at first end of the bundle, and either a cured resin nub or a cured resin tubesheet formed at a second end of the bundle. The bore(s) of the hollow fiber membranes are open at a face of the tubesheet adjacent the first end of the bundle. The tubesheet has an annular structure that encapsulates the hollow fiber membranes and the porous support tube at the first end of the bundle but which does not completely block a bore of the porous support tube, wherein the collection tube has a plurality of orifices formed therein at least at positions adjacent the nub.
