In order to ensure the excellent performance of the membrane, it is necessary to control the surface characteristics and supporting structure of the membrane during the production process of ultrafiltration and microfiltration. At the same time, the membrane material must also have good mechanical properties to ensure that the produced membrane has high strength and flexibility. Moreover, the membrane material should also have excellent anti pollution performance
Commonly used membrane materials include polyvinylidene fluoride (PVDF), polypropylene (PAN), polyether ether (PES), polyethylene (PS), cellulose acetate (CA), polyethylene (PE), polypropylene (PP), polyethylene (PVC), etc. Among them, polyvinylidene fluoride (PVDF) materials are increasingly favored by people due to their unparalleled superior properties.
The biggest characteristic of polyvinylidene fluoride is its extremely high chemical stability. And chemical stability determines its outstanding antioxidant ability and acid and alkali resistance. The most common and headache problem encountered during the application of membranes is membrane fouling. During the water treatment process, microorganisms and organic matter (especially in sewage) in the water often adhere to the surface of the membrane. As the membrane application time increases, these substances will slowly block the membrane pores. This leads to a direct decrease in membrane separation ability. In order to ensure the normal operation of the membrane and stabilize the water flux, it is necessary to regularly clean the membrane. The most effective method to remove these microorganisms and organic matter adsorbed on the membrane surface is oxidant cleaning. But oxidants can cause damage to many membranes. The ability of polyvinylidene fluoride (PVDF) to withstand oxidants (such as sodium hypochlorite) is more than 10 times that of materials such as polyether and maple, greatly extending its service life.
Although both polyvinylidene fluoride and polyvinylidene fluoride have extremely high strength, polyvinylidene fluoride also has extremely strong flexibility. Flexibility is expected in the process of membrane air washing. Therefore, polyvinylidene fluoride is widely used in membrane filtration forms that require air, such as membrane bioreactor (MBR) and membrane modules in the form of external pressure filtration. In the actual case investigation results, it is shown that polyvinylidene fluoride membrane fibers have the lowest wire breakage rate
Due to its extremely low wire breakage rate, high oxidation resistance, high strength, excellent flexibility, and pollution resistance, polyvinylidene fluoride (PVDF) membranes have been increasingly widely used in the field of sewage treatment.
