Influence on Operating Conditions to Fouling Resistance with PVDF Membranes at MBRs

The operation of membrane bioreactors (MBRs) is significantly impacted 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 crucial 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 could result in longer 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.
