A separation system including a pressure vessel containing a plurality of membrane cartridge assemblies is provided for the separation of a fluid feed. The separation system typically includes an elongated pressure vessel having a feed stream inlet, a residual stream and at least one permeate stream outlet. Disposed within the pressure vessel are a first tube sheet assembly defining a first permeate reservoir, a first fluid reservoir, and a plurality of membrane cartridge assemblies. The first tube sheet assembly includes a first pair of tube sheets, which define the first permeate reservoir therebetween, and a plurality of first sleeves disposed between the first pair of tube sheets. The first permeate reservoir is in fluid communication with the at least one permeate stream outlet. The at least one membrane cartridge assembly includes a membrane cartridge and a first permeate adapter joined to a first end of the membrane cartridge.
