A device for filtering and separating pressurized liquid mixtures by means of a membrane includes a substantially pressure-tight container in which the membranes are accommodated in a pressure-tight manner. The container has at least one intake for the mixture, as well as at least one outlet for the permeate separated from the mixture by means of the membranes, and at least one outlet for the retentate, also referred to as a concentrate. The pressure-tight container is made of plastic.

The disclosure relates to devices and methods for extracorporeal conditioning of blood. Extracorporeal blood oxygenators and blood oxygenator components, such as conditioning modules, are described. An extracorporeal blood oxygenator includes a conditioning module having an external frame, an inlet cover, an outlet cover, and an internal chamber. A fiber assembly is disposed within the internal chamber and a potting material on the fiber assembly creates a circumferential seal that defines a passageway through the fiber assembly having a substantially circular cross-sectional shape. A fluid inlet is in fluid communication with the passageway, has a lumen that extends along an axis that is substantially perpendicular to the fiber assembly, and has an internal curvilinear surface adjacent the fiber assembly. A fluid outlet on the opposite side of the fiber assembly also has a lumen that extends along an axis that is substantially perpendicular to the fiber assembly.

A water treatment system comprising a pressure vessel, vertically aligned separation elements within the vessel each having at least one porous UF or MF membrane, feed fluid passageways, a permeate fluid passageway, a concentrate removal port, and a biocontactor within the vessel that has biogrowth surfaces surrounding flow paths through the biocontactor. The flow paths have a median ratio of surface area to volume which exceeds 15 cm.sup.1. The pressure vessel also contains a pressure plate with holes which separates the vessel into two chambers, a first chamber containing membrane elements and a second chamber that contains the biocontactor. A sealing means contacting the pressure plate prevents fluid flow between the first chamber and second chamber except through the porous membranes.

A system for removing a microbe from a liquid comprising: a housing; a microbial filter disposed within the housing; a disinfecting agent disposed in the housing. A flow of the liquid passes through the microbial filter and the disinfecting agent thereby trapping and/or killing the microbe, generating a cleaned liquid.

A hollow fiber module includes hollow fiber cartridges. A port receives a second solution to be treated in a shell side volume and another port for discharging the treated second solution. A first end cap has an inlet for a first solution and a distributer for distributing the first solution to a first end of the hollow fiber cartridges. A second end cap has a collector for collecting the treated first solution from the second end of the hollow fiber cartridges and an outlet for the treated first solution. A first connector has an inlet for the second solution and a distributer for distributing the second solution to a port of the hollow fiber cartridges. A second connector has a collector for collecting the treated second solution from the other port of the hollow fiber cartridges and an outlet for the treated second solution.

There is provided a chemical analyzer equipped with a hollow fiber degassing module that can maintain the original degassing performance even after long periods of continuous use, and can also suppress the proliferation of bacteria and the like. More specifically, a hollow fiber degassing module includes a housing and a hollow fiber membrane disposed in an internal space of the housing. The housing includes a liquid supply unit for connecting an outside of the housing and an internal space of the hollow fiber membrane to each other, and for supplying constant temperature water W, a liquid discharge unit for connecting the internal space of the hollow fiber membrane and the outside of the housing to each other, and for discharging constant temperature water, and a gas discharge unit for connecting an internal space of the housing and the outside of the housing to each other, and for depressurizing the internal space.

There is provided a chemical analyzer equipped with a hollow fiber degassing module that can maintain the original excellent degassing performance even after long periods of continuous use. More specifically, a hollow fiber degassing module 20A includes a housing 210 and a hollow fiber membrane 220 disposed in an internal space S1 of the housing. The housing 210 includes a liquid supply unit 216A for connecting an outside of the housing 210 and an internal space S2 of the hollow fiber membrane 220 to each other, and for supplying constant temperature water W1 from an outside of the housing 210 to an internal space S2 of the hollow fiber membrane 220, a liquid discharge unit 217A for connecting the internal space S2 of the hollow fiber membrane 220 and the outside of the housing 210 to each other, and for discharging constant temperature water W2 degassed from the internal space S2 of the hollow fiber membrane 220 to the outside of the housing 210, a gas discharge unit 218A for connecting an internal space S1 of the housing 210 and the outside of the housing 210 to each other, and for depressurizing the internal space S1 of the housing 210, and a liquid discharge unit 219A that is provided at a vertically lower end portion of the housing 210 for discharging a liquid generated in the housing 210.
