Claim:
A process for fabricating a spiral wound module comprising: a. providing a generally rectangular membrane envelope comprising a first and second membrane sheet, a permeate sheet interposed between the first and second sheet, and an open envelope edge and three sealed envelope edges; b. positioning the open envelope edge relative to a permeate collection tube having holes so that the open envelope edge is in fluid communication with a plurality of the holes; c. positioning a feed spacer sheet adjacent to the membrane envelope; d. winding the membrane envelope and adjacent feed spacer sheet about the permeate collection tube to form a wound membrane scroll having two spaced-apart scroll faces, each face being generally perpendicular to the permeate collection tube; and e. applying a circumferential bead of reactive sealant material proximate to each juncture between the permeate collection tube and a scroll face, wherein the reactive sealant material comprises a cyanoacrylate and is ultraviolet light cured in less than 15 minutes.
