Influence on Operating Conditions to Fouling Resistance of PVDF Membranes within MBRs

The performance of membrane bioreactors (MBRs) is significantly affected by the fouling resistance of the employed membranes. Polyvinylidene fluoride (PVDF) membranes are widely employed in MBR applications due to their favorable 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, solution flow rate, temperature, and pH can substantially modify the fouling resistance. High transmembrane pressures can increase membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate could result in prolonged contact time between the membrane surface and foulants, promoting adhesion and biofilm growth. Temperature and pH variations can also affect the properties of foulants and membrane surfaces, thereby influencing fouling resistance.

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

• Specifically, the incorporation of UV disinfection into an MBR system can effectively destroy pathogenic microorganisms, providing a safer level of water quality.
• Moreover, 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 processes allows for a more comprehensive and efficient wastewater treatment system. This integration holds significant potential for achieving optimized water quality outcomes and addressing the evolving challenges in wastewater management.
