Enhancing Membrane Fouling Mitigation in PVDF MBRs for Wastewater Treatment
Fouling remains a significant challenge in the operation of polyvinylidene fluoride (PVDF) membrane bioreactors (MBRs) used for wastewater treatment. This accumulation of biomass, inorganic materials, and other contaminants on the membrane surface decreases permeate flux and overall system efficiency.
