Also disclosed is a method of manufacturing the spiral wound membrane module.

An artificial lung device includes: a housing which is formed in a tubular shape including both end portions closed, includes a blood inflow port and a blood outflow port, and is arranged such that a center axis of the housing is directed in a lateral direction; a hollow fiber body (gas exchanger) which is arranged in the housing and performs gas exchange with respect to blood while the blood flows from the blood inflow port to the blood outflow port; and a straightening frame (gas guide portion) by which a gas having flowed through the gas exchanger by the flow of the blood is guided to the gas exchanger again in the housing.

A spiral wound membrane module, comprising a perforated core having an axially extending internal bore; at least one membrane packet comprising a folded membrane sheet defining a first outer face, a first inner face, a second outer face and a second inner face, the fold of the folded membrane sheet being a leading end of the membrane packet; a feed sheet positioned between the first and second inner faces so as to be sandwiched by the folded membrane sheet; a first permeate screen adjacent the first outer face of the membrane sheet defining a first permeate channel; a second permeate screen adjacent the second outer face of the membrane sheet defining a second permeate channel; and a fluid impermeable support coupled to the leading edge of the membrane packet. Also disclosed is a method of manufacturing the spiral wound membrane module.

Proposed are a gasket assembly and a fuel cell humidifier comprising the same which can be manufactured with improved productivity and can drastically reduce maintenance costs thereof. The gasket assembly according to an embodiment of the present disclosure is a gasket assembly for a fuel cell humidifier comprising a mid-casing, a cap fastened to the mid-casing, and at least one cartridge disposed in the mid-casing and receiving a plurality of hollow fiber membranes. The gasket assembly includes a packing part provided with a hole into which an end part of the cartridge is inserted, an edge part formed by being connected to the packing part, and a damping part formed on an outer peripheral surface of the cartridge.

A gas-permeable well for use with a bioreactor may include a reinforced gas-permeable membrane. The gas-permeable membrane may include an integrated reinforcing structure such as a stainless steel mesh or perforated screen, and may include an integrated gasket or O-ring, or other regions of increased thickness. A sensor brought into close proximity to the reinforced gas-permeable membrane may take an indirect measurement of a condition of process medium on the other side of the gas-permeable membrane, such as a measurement of dissolved oxygen or carbon dioxide.

A method of using a system includes injecting a liquid mixture from a reservoir to an upper cell; stirring the liquid mixture in the upper cell using a stirrer; separating a first organic constituent from the liquid mixture by absorbing the first organic constituent of the liquid mixture at a first peripheral section of a membrane thereby causing a retentate comprising a second organic constituent and a solvent to reside in the upper cell; desorbing the first organic constituent of the liquid mixture at a second peripheral section of the membrane to obtain a first organic constituent permeate vapor; receiving the first organic constituent permeate vapor in a third feed line of a lower cell; receiving the retentate in a second feed line of the upper cell; and sending the retentate to the reservoir via the second feed line.

A field flow fractionator comprises a top plate, a bottom plate, a channel between the top plate and the bottom plate, an o-ring between the top plate and the bottom plate to form a first seal for the channel, and a membrane along a bottom of the channel. The top plate further comprises a lip extending vertically from the top plate to form a second seal for the channel by directly abutting the membrane.

Proposed is a fuel cell membrane humidifier that can maintain high humidifying efficiency by enabling high-humidity gas discharged from a stack of a hydrogen fuel cell to make uniform contact with the entire upper, middle, and lower parts of a hollow fiber membrane module without a dead zone, and improve airtightness and assemblability between a main housing coupled to a cartridge, an inlet housing, and an outlet housing. The fuel cell membrane humidifier includes the main housing in which a flow-in section forming an inlet portion for humid gas, a flow-out section forming an outlet portion for the gas, and at least one or more cartridge support portions are integrally formed, and a hollow fiber membrane cartridge including at least one or more outer flanges on a cartridge housing, having a plurality of hollow fiber membrane modules inside the cartridge housing, and separating the flow-in section from the flow-out section.
