Influence in Operating Conditions to Fouling Resistance with PVDF Membranes in MBRs
The efficiency of membrane bioreactors (MBRs) is significantly affected 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. more info Parameters like transmembrane pressure, influents flow rate, temperature, and pH can significantly affect the fouling resistance. High transmembrane pressures can increase 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 affect the properties of foulants and membrane surfaces, thereby influencing fouling resistance.
