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 are susceptible to multifaceted fouling mechanisms, such as deposition of extracellular polymeric substances (EPS), microbial growth, and particulate matter accumulation.
These contamination events can drastically decrease the permeate flux, increase energy consumption, and ultimately affect the performance of the MBR system.
Numerous strategies have been implemented to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly categorized into proactive and restorative approaches. Preventive measures aim to reduce 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 clearing existing fouling layers from the membrane surface through physical or chemical cleaning. Physical cleaning methods involve backwashing, air scouring, and manual abrasion, while chemical read more cleaning relies upon agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy depends on the specific fouling mechanisms present in the MBR system and the operational constraints.
