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 tend to susceptible to various fouling mechanisms, including deposition of extracellular polymeric substances (EPS), microbial attachment, and particulate matter accumulation.
These fouling events can drastically diminish the permeate flux, increase energy consumption, and ultimately compromise the performance of the MBR system.
Numerous strategies have been proposed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly grouped into preemptive and restorative approaches. Preventive measures aim to minimize the formation of foulants 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 procedures. Physical cleaning methods involve backwashing, air scouring, and manual scraping, while chemical cleaning relies upon agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy relies on the specific fouling mechanisms present in the MBR system and the operational constraints.
