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 various fouling mechanisms, including deposition of extracellular polymeric substances (EPS), microbial attachment, and particulate matter accumulation.
These contamination events can drastically diminish the permeate flux, increase energy consumption, and ultimately affect the effectiveness of the MBR system.
Numerous strategies have been developed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly categorized into preventive and reactive approaches. Preventive measures aim to reduce 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 procedures. Physical cleaning methods include backwashing, air scouring, and manual abrasion, while chemical cleaning employs agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy varies on the specific fouling mechanisms occurring in the MBR system and the operational constraints.
