摘要:
The invention relates to a filter module comprising a plurality of essentially parallel tubular membranes, the tubular membranes comprising a porous tube wall that functions as a filtering membrane, wherein the module comprises a support structure for supporting the tubular membranes, the support structure comprising an open three-dimensional network of stable shape consisting of stiff wires or fibres, the support structure being shaped such that it comprises open parallel tubes or parts of tubes that envelope each of the tubular membranes at least partly over at least a part of its length, in such a way that a tube or part of a tube of the support structure supports at least one tubular membrane.

An integrated fiber membrane module for air dehydration and air separation includes dehydration and separation units disposed concentrically in a generally cylindrical module. Air flows through the outer dehydration unit, becomes dried, and is then directed, in an opposite direction, through the separation unit. The permeate gas from the separation unit serves as a sweep gas for the dehydration unit. A portion of dried gas produced by the dehydration unit may be used as a sweep gas for the separation unit, and al so for the dehydration unit. The module makes it feasible to dry and separate air using a device which occupies relatively little space, and which is therefore especially suited for use in aircraft and in other cramped environments.
摘要:
A method for filtration of fluid, primarily liquid, with fluid filtration device having a fluid inlet and a fluid outlet and a fluid path between the inlet and the outlet through a microporous filter with a pore size adapted for filtering bacteria or bacteria and virus by mechanical particle size separation. The filtration device comprises further an antimicrobial source adding antimicrobial substance to the fluid in the fluid path between the fluid inlet and the inlet surface of the microporous filter. The fluid filtration device is provided with a design flow through the device, the design flow assuring a proper filtration of the fluid flowing through the device with a cleaned fluid at the flow outlet. The antimicrobial source, for example a halogen source, is configured to release the antimicrobial substance at a low elution rate that is not high enough for killing substantially all the microbes in the fluid during the time it takes the fluid to flow through the device at the design flow, but which is high enough to prevent prevention of a biofilm in the long term.
摘要:
A filtration module comprises a housing having an inlet and an outlet; a plurality of hollow fiber membranes disposed in the housing, each membrane having a wall and a lumen open to the outlet; a porous shell disposed in the housing and encasing the plurality of hollow fiber membranes, the shell having an opening through which ends of the hollow fiber membranes pass; and a plug in the outlet, the ends of the hollow fiber membranes passing through the plug and the shell ending in the plug. A liquid treatment apparatus comprising the filtration module is also disclosed, as are method for making the filtration module and the liquid treatment apparatus.
摘要:
A water purification apparatus comprising a semi-permeable membrane capable of being contacted with a water source; a superabsorbent polymer capable of absorbing water across said semi-permeable membrane; a pressure application surface capable of transmitting pressure to the gel; and a permeable membrane through which absorbed water is capable of being released from the gel upon application of pressure thereto from said pressure application surface, wherein said permeable membrane is isolated in use from the water source by an isolation means
摘要:
A device and methods for extracorporeal treatment of fluids, such as blood, for effective plasmafiltration or hemofiltration alone or in combination with dialysis. The preferred devices (10) is a circuit that may include a dialyzer (20), a plasmafilter (30), a sorbent pump (40) to circulate a treatment sorbent solution, a sorbent container (32), and a leak detector (50) may be located downstream from the filtration member.
