A plethora of strategies have been developed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly classified into preventive and restorative approaches. Preventive measures aim to limit 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 abrasion, while chemical cleaning utilizes agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.
The choice of mitigation strategy depends on the specific fouling mechanisms occurring in the MBR system and the operational constraints.
