BACKGROUND
The invention is directed to the use of flexible, chemically resistant,
fast curing UV curable adhesive to reinforce fold areas and/or seams of
membranes utilized in spiral filtration modules. Spiral filtration modules
are used for microfiltration, nanofiltration, ultrafiltration, reverse
osmosis, and gas separation. Filtration devices of this type typically
comprise a plurality of spiral filtration modules through which a fluid to
be filtered passes.
Figure 4 of the present specification is reproduced below:
Figure 4 illustrates a single spiral filtration module.
The spiral filtration module includes a permeate carrier tube 20 with
leaf packets 16 circumferentially spaced around it. [0032]. A leaf packet
