Influence of Operating Conditions on Fouling Resistance from PVDF Membranes at MBRs

The efficiency of membrane bioreactors (MBRs) is significantly affected by the fouling resistance of the employed membranes. Polyvinylidene fluoride (PVDF) membranes are widely utilized in MBR applications due to their desirable properties such as high permeability and chemical resistance. Operating conditions play a vital role in determining the severity of fouling on PVDF membranes. Parameters like transmembrane pressure, feed flow rate, temperature, and pH can significantly affect the fouling resistance. High transmembrane pressures can accelerate membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate MBR may result in longer contact time between the membrane surface and foulants, promoting adhesion and biofilm growth. Temperature and pH variations could also influence the properties of foulants and membrane surfaces, thereby influencing fouling resistance.

Membrane bioreactors (MBRs) are increasingly utilized for wastewater treatment due to their effectiveness in removing suspended solids and organic matter. However, challenges remain in achieving optimal purification targets. To address these limitations, hybrid MBR systems have emerged as a promising approach. These systems integrate PVDF membranes with various advanced treatment processes to enhance overall performance.

• For instance, the incorporation of UV disinfection into an MBR system can effectively neutralize pathogenic microorganisms, providing a higher level of water quality.
• Additionally, integrating ozonation processes can improve removal of recalcitrant organic compounds that are difficult to treat through conventional MBR methods.

The combination of PVDF membranes with these advanced treatment techniques allows for a more comprehensive and eco-friendly wastewater treatment solution. This integration holds significant potential for achieving optimized water quality outcomes and addressing the evolving challenges in wastewater management.
