Fouling Mitigation Strategies for Polyvinylidene Fluoride (PVDF) Membranes in MBR Systems

Membrane biofouling in Membrane Bioreactor (MBR) systems utilizing Polyvinylidene Fluoride (PVDF) membranes presents a significant challenge to their efficiency and longevity. To combat this issue, various approaches have been investigated to minimize the formation and accumulation of undesirable deposits on the membrane surface. These methods can be broadly classified into three categories: feed water treatment, membrane modification, and operational parameter optimization.

Pre-treatment processes aim to reduce the concentration of fouling agents in the feed water before they reach the membrane. Common pre-treatment methods include coagulation/flocculation, sedimentation, filtration, and UV disinfection. Membrane modification involves altering the surface properties of PVDF membranes to render them more resistant to fouling. This can be achieved through various approaches such as grafting hydrophilic polymers, coating with antimicrobial agents, or incorporating nanomaterials. Operational parameter optimization focuses on adjusting operational conditions within the MBR system to minimize fouling propensity. Key parameters include transmembrane pressure, permeate flux, and backwashing frequency.
