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 multifaceted fouling mechanisms, including deposition of extracellular polymeric substances (EPS), microbial attachment, and particulate matter accumulation.
These contamination events can drastically reduce the permeate flux, increase energy consumption, and ultimately negatively impact the effectiveness of the MBR system.
A plethora of strategies have been implemented to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly grouped into preventive and reactive 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 cleaning. Physical cleaning methods include backwashing, air scouring, and manual removal, while chemical cleaning utilizes 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.
