Abstract
One or more hollow fiber membranes having a coflow of filtrate to provide trans-membrane pressure (TMP) control. The membranes preferably are capable or forming a shear effect or Dean vortices at their inner surface. Optionally, the filtrate channel may contain one or more types of beads, either inert or formed of a capture resin such as affinity chromatography beads or ion exchange resins, for selectively capturing and retaining certain molecules from the filtrate of feedstream. The beads, in addition to the optional capture function, aid in the control of the TMP.
