ABSTRACT:
A membrane-coated substrate and method for forming the membrane coating on the substrate that involves providing a porous inorganic monolithic substrate having one or more through channels having inner surfaces, providing solid polymeric film fusible to the substrate, and joining the film to the substrate by applying the film in a softened state to those inner surfaces and applying pressure thereto, so that the film fuses to and coats the inner surfaces of the channels. A workstream is modified by passing it through the membrane-coated substrate to cause modification of the workstream by the membrane coating.
