摘要

Filter element made of a ceramic material comprises a cylindrical or multi-cornered prismatic outer surface, a central channel and a number of surrounding retentate channels coated with a filter membrane. The center of the surrounding retentate channels (2) is located halfway between the outer surface (1) and the central channel (3). The circumference curvature of the surrounding channels is greater than that of the middle channel and outer surface. The ratio of the filter membrane surface to the total cross-section of the filter element and/or the resulting filtrate throughput with respect to the outer surface and middle channel, is maximized
