IN SITU FILTRATION FOR A BIOCONTAINER
The disclosure herein relates to a TFF assembly including a baffle comprising a microporous filter within a bioreactor. The baffle may include a collection receptacle to capture a target product or waste materials within the baffle after passing through the microporous filter.
Sorbent emitter for direct air capture of carbon dioxide
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.
Separation membrane module
A separation membrane module may decrease a bending load applied to a support member supporting ends of tubular separation membranes and omission of a seal member between the outer circumferential surface of the support member and the inner circumferential surface of a housing. The separation membrane module may include a tubular housing, tubular separation membranes arranged in a longitudinal direction of the housing, end tubes connected to lower ends of the tubular separation membranes, a support box supporting the end tubes, and a backpressure chamber below the support box. The tubular separation membranes may be in communication with a support box collection chamber. A nozzle disposed on the support box may extract permeated fluid. A chamber and the backpressure chamber are in communication via a gap between the support box outer circumferential surface and the inner circumferential surface. The chamber and backpressure chamber have substantially the same pressure.
HYBRID FILTER ASSEMBLY AND METHOD
A two-stage filter enclosed within a single vessel is provided. The two-stage filter is provided in the form of the vessel having a first filtration stage configured to capture particles of a first size, and a second filtration stage downstream of the first filtration stage and in fluid communication with the first filtration stage configured to capture particles of a second size, wherein the first size is larger than the second size. The first filtration stage may comprise a porous media. The second filtration stage may comprise one or more membrane filters.
CARTRIDGE OF FUEL CELL HUMIDIFIER AND FUEL CELL HUMIDIFIER
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.
Assembly-type cartridge block and hollow-fiber membrane module comprising same
The present invention relates to an assembly-type cartridge block enabling various types of cartridges, and a hollow-fiber membrane module comprising the same. The assembly-type cartridge block of an embodiment of the present invention comprises: a body part having a plurality of hollow-fiber membranes therein and having mesh parts formed respectively at the upper and lower parts thereof; and a fastening part formed on a side surface of the body part and configured to be fastened to an adjacent assembly-type cartridge block. Further, the hollow-fiber membrane module of an embodiment of the present invention comprises: a housing unit including a first fluid inlet, a first fluid outlet, a second fluid inlet, and a second fluid outlet; and a cartridge unit installed inside the housing unit and formed by fastening a plurality of assembly-type cartridge blocks, each of the assemble type cartridge blocks having a plurality of hollow-fiber membranes therein.
Flat-plate filter for water treatment and flat-plate filter module comprising same
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.
Disposable device for filtering a large medium volume
A single-use device for filtration of a large volume of medium including a plurality of single-use filter units, at least some of which, preferably all of which, are connected to each other by rigid pipes.
