Abstract: The present disclosure relates to support membranes for filters that include a support sheet formed of a polymeric material and a continuous base section having opposed outer surfaces and spaced-apart ribs extending outwardly from at least one of the opposed outer surfaces. The spaced-apart ribs define continuous flow channels bound by the adjacent spaced-apart ribs. The ratio of the height of the ribs to the height of the continuous base ranges from about 2:1 to about 5:1. This relatively high aspect ratio of the ribs and the base layer increases the performance of the filter and reduces the cross-flow pressure drop of fluids filtered through the membrane.
