The Role of Fouling Mitigation Strategies in PVDF MBR Performance
Fouling remains a significant challenge in the operation of polyvinylidene fluoride (PVDF) membrane bioreactors (MBRs). These deposits of biomass, organic matter, and other constituents on the membrane surface can greatly reduce MBR performance by increasing transmembrane pressure, reducing permeate flux, and affecting overall process efficiency. To address this fouling issue, various strategies have been explored and adopted. These strategies aim to prevent the accumulation of foulants on the membrane surface through mechanisms such as enhanced backwashing, chemical pre-treatment of feed water, or the employment of antifouling coatings.
