Membrane Fouling and Mitigation Strategies in PVDF MBR Systems
Membrane fouling presents a significant challenge in performance of polymeric microfiltration membranes utilized in biological wastewater treatment. Polyvinylidene fluoride (PVDF) membranes, renowned for their chemical robustness and biocompatibility, are frequently employed in these systems due to their remarkable permeability and antifouling properties.

Function of PVDF Membranes in Enhanced Nutrient Removal by MBRs
PVDF films play a crucial function in enhancing nutrient removal within membrane bioreactors (MBRs). Their unique chemical and physical properties contribute to efficient filtration of organic matter, nitrogen, and phosphorus. PVDF membranes exhibit excellent permeability, allowing for a uniform flow of treated water while effectively capturing nutrients within the bioreactor. The compact pore structure of PVDF membranes prevents the flow of suspended solids and microorganisms, promoting transparency in the effluent. Moreover, PVDF's resistance to clogging ensures prolonged membrane effectiveness, minimizing operational challenges.
Fiber Membrane Bioreactor : A Sustainable Solution for Industrial Wastewater Treatment
