PVDF Membrane Fouling Control Strategies in Membrane Bioreactors

Fouling adheres a persistent challenge in membrane bioreactor (MBR) operation. This phenomenon involves the deposition of unwanted materials upon the surface of polyvinylidene fluoride (PVDF) membranes, leading to decreased permeate flux and reduced treatment efficiency. To mitigate such fouling issues, various control strategies have been implemented. Physical methods include backwashing, which aim to remove accumulated deposits by disrupting the adhesion of foulants. Chemical approaches utilize disinfectants or enzymes to degrade organic matter, while biological control strategies leverage microorganisms which activity can reduce fouling formation.

Furthermore, membrane modifications like surface coatings or functionalized designs offer potential for improved resistance to fouling. The selection of an effective ultra-filtration membrane strategy relies on factors such as the nature of the foulants, operating conditions, and specific application requirements. Ongoing research continues to investigate novel approaches for reducing PVDF membrane fouling in MBRs, paving the way for more efficient and sustainable wastewater treatment processes.

Microfiltration: A Key Process in Modern Membrane Bioreactor Technology
