Membrane Fouling Control Strategies in PVDF MBRs for Improved Water Quality
Fouling in film bioreactors (MBRs) is a persistent challenge that affects water purity. Polyvinylidene fluoride (PVDF), a popular membrane material, is susceptible to fouling by organic matter. This deposition hinders the separation process, leading to decreased water output. To mitigate this issue, various control strategies have been developed and utilized.
These comprise pre-treatment processes to eliminate foulants before they reach the membrane, as well as post-treatment strategies such as chemical cleaning to clear accumulated foulants.
Furthermore, alteration of the PVDF membrane surface through functionalization can boost its antifouling properties.
Effective implementation of these control methods is crucial for enhancing the performance and longevity of PVDF MBRs, ultimately contributing to improved water quality.
