MEMBRANE

摘要

A composite porous membrane for use in water treatment comprises an inorganic support having interstices and porous inorganic films of sintered non-metallic particles carried by the support and bridging the interstices thereof. Exterior and interior surfaces of the membrane are provided with a photocatalyst which upon irradiation with electromagnetic radiation of the appropriate wavelength is effective oxidatively to decompose organic materials in water. The preferred photocatalyst is the anatase form of titania.
