Influence in Operating Conditions for Fouling Resistance of PVDF Membranes in MBRs
The performance of membrane bioreactors (MBRs) is significantly influenced by the fouling resistance of the employed membranes. Polyvinylidene fluoride (PVDF) membranes are widely employed in MBR applications due to their positive 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, solution flow rate, temperature, and pH can greatly modify the fouling resistance. High transmembrane pressures can increase membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate may result in increased 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.
