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 multifaceted fouling mechanisms, comprising deposition of extracellular polymeric substances (EPS), microbial colonization, and particulate matter accumulation.
These fouling events can drastically reduce the permeate flux, increase energy consumption, and ultimately negatively impact the efficiency of the MBR system.
A plethora of strategies have been developed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly grouped into preventive and reactive approaches. Preventive measures aim to reduce 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 removing existing here fouling layers from the membrane surface through physical or chemical treatment. Physical cleaning methods include backwashing, air scouring, and manual abrasion, while chemical cleaning relies upon agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy varies on the specific fouling mechanisms existing in the MBR system and the operational constraints.
