Magnetic Dust Purifies Wastewater Efficiently

You can now purify wastewater using nothing but magnetic dust and a simple magnet.

Scientists just created these supercharged iron nanoparticles that act like microscopic trash collectors.

They coated them with a chemical called EDTA which basically makes them sticky to pollutants.

You dump them into dirty industrial water and they instantly latch onto toxic heavy metals like

lead and the stuff that makes water hard. The best part is you don't need massive

energy-draining filters to finish the job. You just wave a magnet over the

water and it pulls the pollution right out. It is cheap, reusable,

and could literally save us from future water shortages.
