Influence in Operating Conditions to Fouling Resistance from 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 used in MBR applications due to their favorable properties such as high permeability and chemical resistance. Operating conditions play a vital role in determining the severity of fouling on PVDF membranes. Parameters like transmembrane pressure, solution 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 may result in longer contact time between the membrane surface and foulants, promoting adhesion and biofilm growth. Temperature and pH variations can also influence the properties of foulants and membrane surfaces, thereby influencing fouling resistance.
