A module has a housing and a tube-sheet. Hollow fiber membranes are potted in the tube-sheet with their ends open. Mechanical interference prevents excessive movement of the tube-sheet along the length of the housing. A gasket is placed in a groove between the tube-sheet and the housing, opening towards the outer face of the tube-sheet. A cap is secured and sealed to the end of the housing. To construct the module, membranes are placed inside of the housing with their ends protruding. A potting fixture is attached to the end of the housing over the ends of the membranes and protruding into the end of the housing so as to form the groove. Liquid potting material is injected into the potting fixture and solidified into a tube-sheet. The potting fixture is removed and the ends of the fibers are cut open. The module may be used, for example, to dehydrate a fermentation product vapour mixture fed through the lumens of the fibres by extracting water vapour permeated into the housing under partial vacuum.
