Abstract

The invention is a fluid separation module with improved permeate flow characteristics. Such modules comprise a hollow fiber bundle, two tubesheets, a tubesheet support which encircles the bundle and is contacted with the outer edge of the inside of both tubesheets, a feed inlet, a permeate outlet, a non-permeate outlet, a core, and one or more baffles for channeling flow, wherein the baffles for channeling flow have one end embedded in the second tubesheet and the second end placed at a short distance from the first tubesheet, with the distance between the end of the baffles for channeling flow and the first tubesheet being sufficient to allow the permeate stream flowing along the baffles for channeling flow to flow to the permeate outlet.
