ABSTRACT:
A cross-flow filtration device which receives a feed stock at a feed end face and separates the feed stock into filtrate and retentate, the device having a structure, preferably a monolith, formed of porous material and defining a number of passageways which extend longitudinally from the feed end face to a retentate end face of the structure. The structure further includes a number of longitudinal filtrate chambers and a filtrate collection volume extending into the structure and communicating with the filtrate chambers. The filtrate chambers are distributed among the passageways to provide low pressure drop flow paths for filtrate flow through the porous material from the passageways to nearby filtrate chambers, and at least some of the passageways are separated from filtrate chambers by intervening passageways, thereby enabling a high ratio of passageway surface area to volume of the device and a high rate of filtrate removal.
