Magnetic confinement-enabled membrane reactor for enhanced removal of wide-spectrum contaminants in water: Proof of concept, synergistic decontamination mechanisms, and sustained treatment performance

•A magnetic confinement-enabled membrane chemical reactor is developed.•Magnetic confinement engineering achieves efficient loading, spatial dispersion, and ultrahigh hydrodynamic stability of ZVI.•The HF-MCR enables synergistic and much enhanced removal of NPs, BPA and P.•Magentic gradient and hydrodynamic forces continuously depassivate the ZVI surface.•Perodic ZVI reloading ensures sustainable reactivity and lasting decontamination.
