Abstract
A process for making a fluid processing module is provided wherein a plurality of filtration elements is alternated with a fluid porous layer to form a stack. The filtration elements comprise a membrane sheet having a thermoplastic element bonded to a portion of an edge of the membrane. An opening is provided either through the membrane or through the thermoplastic element. A portion of the thermoplastic element extends into the opening and can be sealed to an adjacent positioned thermoplastic element to seal the porous sheet positioned between adjacently positioned membranes from fluid communication with the opening. Sealing can be effected by extending a heating element through the opening of the stack to effect simultaneous sealing of a plurality of thermoplastic elements.
