In conjunction with a method of producing a fluid purifier membrane module, sheets of membrane material are disposed in layers with intermediate spacer elements in a manner to obtain mutually alternating spaces for contaminated and purified fluid respectively, it is proposed, among other things, that mutually adjoining sheets of membrane material (12) are joined together in pairs in a manner to obtain membrane units (10) which include closed cavities (28), and that the membrane units (10) with associated spacer elements (18, 34) are arranged in a stack, and that the mutually facing outer surfaces of the membrane units are joined together in zones and in a fluid-tight fashion along at least one line (36) which extends through the walls of the membrane units, and that the membrane units are perforated along the line in a manner to obtain through the membrane units a passageway (32) which communicates with the cavities (28). The invention also relates to a membrane module produced in accordance with the method. <IMAGE> |
