Water Treatment System Using a Magnetic Confinement Method

This groundbreaking water treatment system offers an efficient and sustainable solution for decontaminating complex waters. It uses parallel magnetic fields to enable targeted reactions, resulting in effective decontamination. At its core, the system consists of a flow-through chemical reactor and permanent rubidium magnets. Its key feature is the assembly of magnetic (catalytic) materials into forest-like arrays of porous needles. These structures enable specific reactions that effectively remove contaminants from water. Two specific structural configurations are developed to address typical water treatment scenarios. The first configuration involves a hollow fibre membrane chemical reactor, which integrates sequential membrane separation, and high and sustainable Fenton-like catalysis. This design enables the system to achieve high and synergistic wide-spectrum decontamination. The second configuration centres around a magnetic confinement-enabled zerovalent iron column reactor, coupled with periodic ultrasonic depassivation. This setup excels in removing arsenic from water by reacting with in situ generated iron (oxyhydr)oxides, which result from the oxidative corrosion of zerovalent iron. This novel water treatment system, enabled by magnetic confinement engineering, is also promising for the efficient and sustainable decontamination of industrial wastewater.
