Influence of Operating Conditions on Fouling Resistance of 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 utilized 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, feed flow rate, temperature, and pH can significantly influence the fouling resistance. High transmembrane pressures can promote membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate could result in increased 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.
