Abstract:
Ultrafiltration membranes have been widely used in industrial technology due to their high removal effectiveness. Long-term use of membranes will reduce membrane performance, so cleaning is required to maintain stable membrane performance. Chemical cleaning has proven to be effective for removing impurities but can also have a negative impact on membrane life. Polyethersulfone (PES) is proven to have strong mechanical properties due to its hydrophobic nature, but this hydrophobic nature makes PES membrane performance less than optimal so a hydrophilic pluronic co-polymer is needed.

This research project introduced a novel membrane coating strategy to combat biofouling, which is a major problem for the membrane-based treatment of agricultural and municipal wastewaters. The novelty of the strategy is that the membrane coatings have the unique ability to switch reversibly between passive (antifouling) and active (antimicrobial) fouling control mechanisms. This dual-mode approach differs fundamentally from other coating strategies that rely solely on one mode of fouling control.
