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

These contamination events can drastically diminish 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 grouped into preventive and corrective approaches. Preventive measures aim to reduce 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 procedures. Physical cleaning methods encompass backwashing, air scouring, and manual abrasion, while chemical cleaning relies upon agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy varies on the specific fouling mechanisms occurring in the MBR system and the operational constraints.
