ABSTRACT:
An improved spiral wound reverse osmosis or ultrafiltration membrane cartridge has the inner end and side areas of a permeate transfer leaf sealingly attached to its central collection tube surface, with sealing adhesive applied as band areas near each side edge of the proximate transfer leaf surface in amount in excess of the amount to substantially fill a pair of circumferential grooves in the collection tube when the assembly, including the permeate transfer leaf is spirally wound around it. The adhesive seal is preferably cured at room temperature with the cartridge standing on one of its ends for a period of about 12 to 24 hours. In an alternative embodiment, resilient O rings may be seated in the collector tube grooves, and an additional pair of grooves within the side band areas may also be filled with adhesive.
