ABSTRACT:
A module, utilizing a spirally wound membrane envelope, and adapted to be fitted into a containment tube of a fractionator, has a lip seal between the module and the containment tube, there being small apertures in the lip of the seal arranged and directed so as to allow a small controlled flow to continually bypass the module and thus prevent the product from becoming stagnant behind the seal.
