ABSTRACT:
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. 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). The membrane units (10) with associated spacer elements (18, 34) are arranged in a stack. 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. 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).
