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 various fouling mechanisms, such as deposition of extracellular polymeric substances (EPS), microbial growth, and particulate matter accumulation.
These fouling events can drastically diminish the permeate flux, increase energy consumption, and ultimately negatively impact the performance of the MBR system.
A plethora of strategies have been developed to mitigate PVDF MBR membrane fouling in PVDF-based MBRs. These strategies can be broadly classified into proactive and restorative 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 treatment. 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 existing in the MBR system and the operational constraints.
