Abstract
The membrane module according to the invention is characterized in that it has concrete flanges. This membrane module is made by first sealing a bundle of ceramic fiber membranes at one end using a viscous sealant and then pressing it into a fluid mass of concrete in a mould. After the mass of concrete has hardened the process is repeated with the other end of the bundle. Finally the ends of the fiber membranes are opened by sawing off a slice of the flanges.
