MODULE FOR FLUIDIZING FRACTIONATION TYPE PORE DIFFUSION MEMBRANE SEPARATION CONSTITUTED BY FLOW PASSAGE WITH CIRCULAR CROSS SECTION

摘要

PROBLEM TO BE SOLVED: To provide a module for pore diffusion membrane separation capable of maximally utilizing fluidizing fractionation effect in which a utilizing membrane is a flat porous membrane.MEANS FOR SOLVING THE PROBLEM: A module for pore diffusion membrane separation is characterized by that: all of wall surfaces in a pore diffusion region existing along the flow passage of a processing object liquid are constituted by porous flat membrane surfaces; the shape of the cross section of the flow passage vertical in a flow passage direction of a membrane is circular; a wall is a flat membrane molded to be cylindrical; and the surface of the flat membrane forms the surface of the wall and has at least one support being in close contact with the external surface (that is, the rear surface of the flat membrane) of the wall and extending in the flow passage direction.SELECTED DRAWING: Figure 1
