Influence in Operating Conditions for Fouling Resistance from PVDF Membranes at 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 essential role in determining the severity of fouling on PVDF membranes. Parameters like transmembrane pressure, feed flow rate, temperature, and pH can greatly affect 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 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.
