Abstract
A membrane filtration module is provided incorporating a seal assembly to seal the annular space or bypass channel existing between the outer diameter of the filtration cartridge and the inner diameter of the housing in which it is disposed. The seal assembly prevents a feed stream from entering the bypass channel, and includes a pair of seals each having a flexible gasket and a sleeve extending perpendicularly therefrom, the sleeve being adapted to be positioned directly on the cartridge. This positioning prevents the feed stream from ever coming into contact with the housing.
