HOLLOW FIBER MEMBRANE MODULE

PURPOSE:To permit hollow fiber membranes to be prevented effectively from damages at the time of joining thereof into a module, reception thereof into a module container and disjoining thereof by protecting the periphery of bundled hollow fibers by solid fibers. CONSTITUTION:A number of synthetic resin-made hollow fibers 1 are bundled and both ends thereof are adhesively secured with potting material 2 with at least either end left open. Synthetic resin-made solid fibers 3 are provided over the substantially entire surface of the bundled hollow fibers 1 located on the outermost periphery thereof. As a result, since the periphery of the hollow fiber bundle is protected by the solid fibers, at the time of joining thereof into a module, reception thereof into a module container and disjoining thereof, the hollow fibers can be prevented effectively from damage. Therefore, when the various kinds of gases or liquids are subjected to membrane separation using such a module, the separating operation can be effected with the separation efficiency maintained at a satisfactory degree.
