Optimizing Flux and Fouling Control in Polyethersulfone (PES) MBRs
Effective operation of membrane bioreactors (MBRs) relies heavily on mitigating both flux decline and fouling. Polyethersulfone (PES) membranes, renowned for their excellent mechanical strength and permeability, frequently face challenges related to fouling. This can result in reduced transmembrane pressure (TMP), decreased permeate water quality, and increased operational costs. Techniques to optimize flux and control fouling in PES MBRs encompass a multifaceted approach, involving pre-treatment of influent wastewater, membrane surface modifications, optimized operational parameters, and effective backwashing procedures. By incorporating these strategies, it is possible to enhance the longevity and overall performance of PES MBR systems, thereby contributing to sustainable water treatment processes.
