The film is a kind of inorganic or polymeric materials with speciaselectivity function, it can put the fluid into two separate partswhich are not communicated, so that one or several of themthrough, and other substances separated. The membraneseparation technology with its high effciency, energy saving!environmental protection and molecular fltration characteristicshas been widely used in medicine, water treatment, chemicaindustry, electronics, food processing and other felds, hasbecome one of the most important technologies in this century oseparation science. ls recognized as one of the most importantindustrial technoloay in twenty-frst Century membranetechnology, is a new green industrial technology
The inorganic ceramic membrane separation technology is aseparation technology and sieving effect of porous ceramicmaterial based on the material, with the traditional "dead endand "cake filtration" flter "different dynamic cross fow fltratiormethod: pressure driven membrane pipe inside the raw liquid inthe flm surface with the velocity of high speed flow the smalmolecules (liquid) along the vertical direction and through themicroporous membrane, large molecules (or solid) is to achievethe separation of membrane, fluid concentration and purificationpurposes.
