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 multifaceted fouling mechanisms, including deposition of extracellular polymeric substances (EPS), microbial growth, and particulate matter accumulation.

These fouling events can drastically reduce the permeate flux, increase energy consumption, and ultimately affect the efficiency 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 preemptive and restorative 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 scraping, while chemical cleaning employs agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.

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