ABSTRACT:
A honeycomb structure for fluid filtration includes a support of porous ceramic material having a multiplicity of axially parallel passageways extending therethrough and uniformly spaced by porous partition walls to permit flow of fluid under pressure passing therethrough and a selective membrane coated onto the surface of the passageways to separate one or more components from the fluid and to permit flow of filtrate passing therethrough to be carried through the porous partition walls to the exterior surface of the partition walls for collection. In the honeycomb structure, the partition walls are formed to permit the passage of filtrte at a flow quantity more than twenty times the flow quantity of filtrate passing through the selective membrane and partition walls, and an average pore size of the selective membrane is about from 10 to 10000 angstroms.
