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

The efficiency 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, solution flow rate, temperature, and pH can significantly influence the fouling resistance. High transmembrane pressures can accelerate 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 foulants, promoting adhesion and biofilm growth. Temperature and pH variations may also influence the properties of foulants and membrane surfaces, thereby influencing fouling resistance.
