Membrane Fouling and Mitigation Strategies in PVDF MBR Systems
Membrane fouling presents a significant challenge in performance of polymeric nanofiltration membranes utilized in biological wastewater treatment. Polyvinylidene fluoride (PVDF) membranes, renowned for their mechanical robustness and biocompatibility, are frequently employed in these systems due to their superior permeability and antifouling properties. However, the adhesion of organic matter, inorganic precipitates, and microbial biofilms can significantly diminish membrane productivity, leading to increased operating costs and reduced wastewater quality. To mitigate the detrimental effects of fouling, various strategies have been implemented. These include advanced processes to reduce the concentration of foulants in the feed stream, implementation of physical cleaning protocols, modification of membrane surfaces to enhance their antifouling characteristics, and integration of passive anti-fouling mechanisms.
