Jul 01, 2019· Our method electrolyzes the water molecules into H+ and OH- ions. This process draws out potentially harmful elements like aluminum, antimony, arsenic, barium, cadmium, lead, silver and uranium. The hydrogen ions positively charge the water and draw out the negatively charged ions of the toxins, binding any heavy metals like a magnet.
