Degassing/aeration membrane module

An external circulation-type hollow fiber membrane module which has a high processing capacity and which is capable of inhibiting a to-be-treated liquid within a case from flowing through a short path and efficiently bringing the liquid into contact with a hollow fiber membrane in whichever direction of a vertical direction, a horizontal direction, etc., the liquid flows. An external circulation-type hollow fiber membrane module is provided with: a hollow fiber membrane bundle; a case; and a short-path prevention body that blocks flowing of a to-be-treated liquid in a gap between the hollow fiber membrane bundle and the case, wherein a first end of the hollow fiber membrane bundle is fixed in the case, and the short-path prevention body is provided to the downstream side of a first port which is a liquid flow-in port in the case so as to project from the inner surface of the case.

External circulation-type hollow fiber membrane module

The present invention pertains to a hollow fiber membrane module () for removing gas from an objective liquid or supplying gas to the objective liquid, comprising: a hollow fiber membrane bundle (); and a collecting member () configured to collect first ends () of the hollow fiber membrane bundle () while maintaining openings of opened end portions () of hollow fiber membranes () of the hollow fiber membrane bundle (), wherein the collecting member () has a coupling portion configured to couple the collecting member () to an installation object in a detachable and liquid-tight manner.

Hollow fiber membrane module, degassing and gas supplying device, inkjet printer, and device for manufacturing carbonated spring

Disclosed herein is a hollow fiber membrane module provided with a hollow fiber membrane bundle, a case in which the hollow fiber membrane bundle is contained, a fixation part which affixes the hollow fiber membrane bundle within the case and divides the space inside the case into a first space that is outside the hollow fiber membranes and a second space that is in communication with the insides of the hollow fiber membranes, and a partition plate which divides the first space into a first region and a second region.

Hollow fiber membrane module

Provided is a filtration device exhibiting a high water treatment capacity and capable of increasing the longevity of a hollow-fiber filter, in a water purification device not requiring a purification material and requiring a high water treatment capacity. The filtration device () has: a housing case () having a water inlet unit and a water outlet unit arranged on one end side thereof; and a membrane module () provided inside this housing case (). A first flow path () for causing raw water that has flowed in from the water inlet unit () to flow further to the other end side of the housing case () than the membrane module (), and a second flow path () for causing the raw water that has flowed further to the other end side of the housing case () along this first flow path () to pass through the membrane module () and flow to the water outlet unit () are provided inside the housing case (). A spacer () is provided on the upstream side of the membrane module () in the second flow path ().

Filtration device

A potting material for membrane modules which is formed of an epoxy resin composition, in which the mass change ratio of a cured product of the epoxy resin composition after being immersed in diethylene glycol methyl ethyl ether at 40&#xb0; C. for one week is &#xb1;10% or less, and the mass change ratio thereof after being immersed in tetrahydrofurfuryl acrylate at 40&#xb0; C. for one week is &#xb1;5% or less, and a hollow fiber membrane module which uses the potting material for membrane modules.

Potting material for membrane modules and hollow fiber membrane module using same

The present invention relates to a external-perfusion hollow-fiber membrane module containing a hollow-fiber membrane bundle including a plurality of hollow-fiber membranes; and a casing that houses the hollow-fiber membrane bundle, wherein the hollow-fiber membrane bundle has one end that is fixed to an inside of the casing by a potting portion in an open state, and the external-perfusion hollow-fiber membrane module is configured to perform degassing on a gas contained in a liquid inside the casing, the gas being introduced into an inside from an outer surface of the hollow-fiber membrane.
