Abstract
Disclosed, herein is a single pass cross flow filtration system comprising: a filtration module, comprising two or more filtration segments fluidly connected in series, each having an upstream side and a downstream side; wherein each filtration segment comprises hollow fiber filter membranes, and wherein, when in use, the desired permeate flux is controlled by a configuration comprising: each filtration segment having a selected length; the hollow fiber filter membranes of each filtration segment, having a selected lumen diameter, wherein the selected inner diameter of each filtration segment may be the same or different, provided that at least one selected lumen diameter differs from another selected lumen diameter, and provided that the two or more filtration segments are arranged such that for a given filtration segment, having a selected lumen diameter, no filtration segment on the upstream side of the given filtration segment has a selected lumen diameter that is larger; and one or more pumps, mounted in the permeate channel.
