The raw materials of the mbr uf membrane can be divided into organic membranes and inorganic membranes, but the cost of inorganic membranes must be higher, so they are rarely used in my country. MBR membranes are generally organic membranes, and the raw materials for membrane production are high-pressure polyethylene, polypropylene, etc.
The main factor of the long-term operation of the mbr uf membrane that causes the flux attenuation is the environmental pollution of the membrane module. The larger the relative molecular mass of membrane interception, the stronger the flux attenuation and the lower the repair rate of chemical water treatment. For immersed MBR components, reverse osmosis ro membrane or microfiltration membrane can be selected. Since the gel layer on the membrane surface can also have a filtering effect, when solving urban sewage, there will be no significant difference in the amount of water produced by the microfiltration membrane component or the reverse osmosis ro membrane after the solution, so the immersed MBR component is generally selected as 0.1 ~0.4μm microfiltration membrane.
When choosing the model and specification of the membrane, the choice must be made according to the specific manufacturing requirements, so that the resolved water meets the consumer's application requirements.
