An artificial, extracorporeal system for liver replacement and/or assistance, comprises a liver dialysis device for conducting hemodialysis on a patient suffering from liver failure. The liver dialysis device comprises a first standard hollow fiber membrane dialyzer which does not allow passage of an essential amount of albumin over the membrane wall and which is perfused with the patient's blood, and a second hollow fiber membrane dialyzer which allows the passage of essential but defined amounts of albumin over the membrane wall and which receives the blood of the first standard hemodialyzer. The filtrate space is closed off from the lumen space of the hollow fibers and is populated by adsorbent material which may comprise one or more different adsorbents.

A method for forming a ceramic membrane module system includes disposing at least one membrane (118) within a housing (120), the membrane (118) having capillaries therein. The method includes sealing the first housing end (122) and capillaries, applying force to the removable gasket with an external frame assembly (200), and disposing potting material into the housing (120) without plugging the capillaries with the potting.

A method for forming a ceramic membrane module system includes disposing at least one membrane within a housing, where the membrane has capillaries therein. The method includes sealing the first housing end and capillaries, applying force to the removable gasket with an inflatable bladder assembly or piston assembly, and disposing potting material into the housing without plugging the capillaries with the potting material.

Hollow fiber membranes are potted by injecting a liquid material into a substantially closed cavity (44) containing the fibers. The cavity may be formed in part by the interaction of a mold a permeate pan (52) and a layer of an adhesive pre-applied to a bundle of the membranes.

An energy-saving filtering system and a hollow fiber membrane module for the same are disclosed. According to the filtering system of the present invention, pretreated feed water flows into the case of the hollow fiber membrane module by gravity, and the filtrate passing through the hollow fiber membrane is discharged from the hollow fiber membrane module by gravity.

The present invention relates to novel cartridges and modules for separation of fluid mixtures, especially for gas separation, to a process for production thereof and to a method of use thereof.

A membrane fibre bunch for use in a membrane-aerated biofilm reactor (MABR), the membrane fibre bunch comprising: a group of membrane fibres arranged as a bunch (4) of vertical or horizontal membrane fibres attached at either end to an gas supply manifold (8) within the housing, with each fibre having a lumen containing a gas phase; and a means for connecting the group of membrane fibres so that the gas can flow within the lumen of the membrane; wherein the group of membrane fibres are maintained in position by a connector or overmold (10), the connector or overmold configured to maintain the group of membrane fibres (2) in a spaced-apart configuration from one another and the cross-section of the connector/overmold being of non-circular shape such as ellipsoidal, star-shape etc.

The present disclosure relates to a process for producing a filtration and/or diffusion device, e.g., a capillary dialyzer or an ultrafilter.
