Influence in Operating Conditions for Fouling Resistance from PVDF Membranes within MBRs
The performance of membrane bioreactors (MBRs) is significantly influenced by the fouling resistance of the employed membranes. Polyvinylidene fluoride (PVDF) membranes are widely used 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, influents flow rate, temperature, and pH can substantially modify 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 could also modify the properties of foulants and membrane surfaces, thereby influencing fouling resistance.
