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 tend to susceptible to multifaceted fouling mechanisms, such as deposition of extracellular polymeric substances (EPS), microbial colonization, and particulate matter accumulation.
These contamination events can drastically decrease the permeate flux, increase energy consumption, and ultimately compromise the efficiency of the MBR system.
Several strategies have been implemented to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly classified into preventive 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 clearing existing fouling layers from the membrane surface through physical or chemical procedures. Physical cleaning methods include 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 occurring in the MBR system and the operational constraints.
