What is the MBR film?
1. Polymer organic film materials: polyolefin, polyethylene, polyacrylonitrile, polysulfone, aromatic polyamide, fluoropolymer, etc.
Organic membrane cost is relatively low, cost cheap, membrane manufacturing technology is relatively mature, the membrane pore size and form are more diverse, widely used, but running process easy to pollution, low intensity, short service life.
2. Inorganic film: it is a kind of solid film, which is made from inorganic materials such as metal, metal oxides, ceramics, porous glass, zeolite, inorganic polymer materials, etc.
At present, a lot of use of inorganic membrane in the MBR for ceramic membrane, the advantages are: it can be in the pH = 0 ~ 14, pressure P < 10 mpa, temperature < 350 ℃ environment, its high flux, energy consumption is relatively low, very competitive in the high concentration of industrial wastewater treatment;
The disadvantage is that it is difficult to fabricate expensive, alkali, elastic and film processing.
