Membrane Fouling and Mitigation Strategies in PVDF-Based MBRs
Membrane fouling presents a significant challenge for the performance and longevity of polymeric membrane bioreactors (MBRs).

These deposition events can drastically reduce the permeate flux, increase energy consumption, and ultimately compromise the effectiveness of the MBR system.
A plethora of strategies have been proposed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly categorized into preventive and reactive approaches. Preventive measures aim to limit the formation of contaminants on the membrane surface by optimizing operational parameters such as transmembrane pressure (TMP), hydraulic retention time (HRT), and feed water quality.
Corrective methods, on the other hand, focus on clearing existing fouling layers from the membrane surface through physical or chemical treatment. Physical cleaning methods involve backwashing, air scouring, and manual removal, while chemical cleaning employs agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy depends on the specific fouling mechanisms occurring in the MBR system and the operational constraints.
