Influence of Operating Conditions on Fouling Resistance with PVDF Membranes within 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 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 significantly affect the fouling resistance. High transmembrane pressures can accelerate membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate could result in prolonged contact time between the membrane surface and foulants, promoting adhesion and biofilm growth. Temperature and pH variations can also modify the properties of foulants and membrane surfaces, thereby influencing fouling resistance.
