  • Method for producing a hollow fiber membrane module or a capillary membrane module
    Patent number: 6887304
    Abstract: The invention relates to a method for producing a hollow fiber membrane module or a capillary membrane module as well as a device having such a module. In the method, hollow fibers or capillaries are placed, in an unsintered state, in a mold structured for receiving the hollow fibers or capillaries and are sintered once inside the mold. Subsequently or simultaneously, the fibers are potted in the mold. The method permits producing hollow fiber membrane modules or capillary membrane modules in a simple manner with little risk of breakage.
