    摘要: An improved method of fabricating a spiral wound module seals a juncture between each scroll face, preferably a smooth, trimmed scroll face, and a central permeate tube. The tube is generally perpendicular to the scroll face. Modules produced using the improved method have fewer insertion point leaks than those produced without using the improved method.

    摘要: Various methods for testing spiral wound modules by thermal imaging are described. In a preferred embodiment, the method(s) includes flowing a gas between a scroll face and permeate collection tube of a spiral wound module and detecting temperature differences on the scroll face. Temperature differentials on the scroll face may be captured as a thermal image. The location(s) of temperature differentials on the scroll face can be correlated to defects in the module. In preferred embodiments, the subject test methods are non-destructive and can be applied to spiral wound modules in either a dry or wet condition.
