<p>Module assembly has at least two spacer frame elements (12) each having opposed spaced faces surrounding an opening (22), with each face having an inner peripheral portion and an adjacent outer peripheral portion. A porous membrane (14) may be bonded to one inner peripheral surface of each frame element (12) or to each inner peripheral surface of one frame element. The outer peripheral surface of an adjacent frame element, on a face which does not carry a membrane on its adjacent inner peripheral surface, is bonded to the outer peripheral surface on the face of a frame carrying a membrane to form a continuous bond between the outer peripheral surfaces of the spacer frames, and to define a compartment between membranes through which a fluid may flow from an inlet to an outlet provided in one of the support frames. A membrane support frame carrying a membrane on a face not adjacent another frame can have an alternative device (16) bonded to the periphery to support the membrane.</p> |
