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). Particularly, polyvinylidene fluoride (PVDF)-based MBRs are susceptible to multifaceted fouling mechanisms, such as deposition of extracellular polymeric substances (EPS), microbial attachment, and particulate matter accumulation.
These deposition events can drastically diminish the permeate flux, increase energy consumption, and ultimately compromise the effectiveness of the MBR system.
Several strategies have been implemented to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly grouped into preemptive and reactive approaches. Preventive measures aim to minimize 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 eliminating existing fouling layers from the membrane surface through physical or chemical cleaning. Physical cleaning methods involve 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 existing in the MBR system and the operational constraints.
