Membrane Fouling Control Strategies in PVDF MBRs for Improved Water Quality
Fouling in membranes bioreactors (MBRs) is a persistent challenge that reduces water purity. Polyvinylidene fluoride (PVDF), a widely used membrane material, is susceptible to fouling by biological matter. This accumulation obstructs the filtration process, leading to lowered water flow. To mitigate this issue, various control strategies have been developed and implemented.
These encompass pre-treatment processes to remove foulants before they reach the membrane, as well as post-treatment strategies such as chemical cleaning to remove accumulated foulants.
Furthermore, engineering of the PVDF membrane surface through functionalization can improve its antifouling properties.
Effective implementation of these control strategies is crucial for maximizing the performance and longevity of PVDF MBRs, ultimately contributing to improved water quality.
