Influence in Operating Conditions on Fouling Resistance from PVDF Membranes in MBRs

The operation of membrane bioreactors (MBRs) is significantly impacted 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 substantially modify the fouling resistance. High transmembrane pressures can promote membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate may result in longer contact time between the membrane surface and website foulants, promoting adhesion and biofilm growth. Temperature and pH variations may also affect the properties of foulants and membrane surfaces, thereby influencing fouling resistance.

Hybrid 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 solution. 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 more level of water quality.
• Additionally, 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 processes allows for a more comprehensive and sustainable wastewater treatment system. This integration holds significant potential for achieving enhanced water quality outcomes and addressing the evolving challenges in wastewater management.
