Membrane Fouling and Mitigation Strategies in PVDF-Based MBRs

Membrane fouling constitutes a significant challenge for the performance and longevity of polymeric membrane bioreactors (MBRs). Particularly, polyvinylidene fluoride (PVDF)-based MBRs can be susceptible to diverse fouling mechanisms, such as deposition of extracellular polymeric substances (EPS), microbial colonization, and particulate matter accumulation.

These deposition events can drastically diminish the permeate flux, increase energy consumption, and ultimately affect the efficiency of the MBR system.

Numerous strategies have been developed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly categorized into proactive and restorative approaches. Preventive measures aim to reduce the formation of deposits 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 removing existing fouling layers from the membrane surface through physical or chemical treatment. Physical cleaning methods encompass backwashing, air scouring, and manual removal, while chemical cleaning relies upon agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.

The choice of mitigation strategy depends on the specific fouling mechanisms present in the MBR system and the operational constraints.
