A support structure in the form of a foraminous screen netting having an upper plurality of strands arranged in parallel fashion and intersecting at an angle with a lower plurality of strands, also arranged in parallel fashion. Each strand provides a ridge whose apex extends in a direction generally normal to the plane of the screen upon which is supported substantially by line contact a semipermeable dialyzing membrane. Between each ridge is a groove into which extend channels defined in the membrane by the ridges. |
