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

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

Integrated Membrane Bioreactors: Combining PVDF Membranes with Advanced Treatment Processes

Membrane bioreactors (MBRs) are increasingly utilized for wastewater treatment due to their efficiency in removing suspended solids and organic matter. However, challenges remain in achieving high-level 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.
• Furthermore, integrating ozonation processes can improve degradation of recalcitrant organic compounds that are difficult to treat through conventional MBR methods.

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