Summary: This research developed a zwitterionic copolymer, poly(OxMA-co-SBMA), with aldehyde functional groups for nucleophilic addition reactions and SBMA units for antifouling properties. The copolymer was grafted onto an amine-based substrate using dip-coating technology, resulting in nonfouling and antiprotein properties. The optimized copolymer exhibited improved hydrophilicity and resistance to protein adsorption, as well as reduced blood cell activation, tissue cell adhesion, and bacterial attachment. The dip-coating method offers a fast and simple procedure for achieving biofouling resistance in biomedical materials.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
