Filtration device or membrane device with increasing thickness walls

摘要: This invention is directed at a cross-flow filtration device for receiving feed stock and separating the into filtrate retentate, comprising multicellular monolith structure (10) having central longitudinal axis (11) peripheral surface (12). The has both an inlet outlet end face matrix of porous walls which define plurality cells (20); these mutually parallel extending longitudinally between faces. exhibit uniform transverse cross section throughout each respective cell's length cross-section shape variable when compared to least one other cell such that all equivalent hydraulic diameter. Lastly, structure's increasing aggregate wall thickness (21-28) in direction as approach surface.
