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 monolith with at least one filtrate network. The monolith is formed of porous material and defines a number of passageways which extend longitudinally from the feed end face to a retentate end face of the monolith. The filtrate network includes a number of longitudinal filtrate chambers and one or more filtrate channels which transect the chambers. The filtrate channel communicates with at least one filtrate duct that discharges filtrate from one or both end faces of the monolith. 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.
