Influence in Operating Conditions to Fouling Resistance from PVDF Membranes at MBRs
The operation of membrane bioreactors (MBRs) is significantly impacted by the fouling resistance of the employed membranes. Polyvinylidene fluoride (PVDF) membranes are widely used 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, influents flow rate, temperature, and pH can greatly influence the fouling resistance. High transmembrane pressures can accelerate membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate can 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.
