Influence of 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 positive 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 significantly influence 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 increased 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.
