POSITIVE PRESSURE TYPE HOLLOW FIBER MEMBRANE MODULE

摘要

PURPOSE: A pressurized hollow fiber membrane module is provided to prepare a complex hollow fiber membrane using tubular braids and to be obtained using the complex hollow fiber membrane. CONSTITUTION: A pressurized hollow fiber membrane module includes a module case(140), a complex hollow fiber membrane bundle, a first fixing part(120), and a second fixing part(130). The module case includes a feed water inlet(141) and a filtered water outlet(142). The complex hollow fiber membrane bundle is positioned in the module case. One end part of the bundle is potted to the first fixing part, and the first fixing part is bonded to the inner side of the module case. Another end part of the bundle is potted to the second fixing part, and the second fixing part is bonded to the inner side of the module case. The bundle is composed of complex hollow fiber membranes(110). Each complex hollow fiber membrane includes tubular braid and a polymer resin film.
