Z18 Engineering has developed recyclable magnetic nanoparticles (RMNPs) coated with an Amine-PEG ligand to eliminate PFAS from water, wastewater, and sludge. These nanoparticles bond with PFAS through surface ligands and separate PFAS from the media under the influence of a magnetic field. The RMNPs are reusable, highly efficient, and more cost-effective compared to conventional treatment technologies. The technology also has the potential for customization to target specific pollutants and can be applied to wastewater sludge treatment
