Optimizing Operation Parameters in a Novel Polyvinylidene Fluoride (PVDF) MBR System
Membrane Bioreactors (MBRs) have gained popularity as an effective wastewater treatment technology due to their high removal rates of organic matter and suspended solids. Polyvinylidene fluoride (PVDF) membranes exhibit superior performance in MBR systems owing to their hydrophobicity.

Influence in Operating Conditions for Fouling Resistance of PVDF Membranes in 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 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, 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 increased contact time between the membrane surface and foulants, promoting adhesion and biofilm growth. Temperature and pH variations could 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 robustness 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.
- Considerably, 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 degradation of recalcitrant organic compounds that are difficult to treat through conventional MBR methods.
