How the Ozone Kits clear your waterAnimation: dirty borehole water fills the tank through the NanoJet™. The ozone generator switches on and the venturi draws ozone into the jet; dissolved iron and manganese oxidise, particles clump and settle as sludge to drain or filter out. Iron removal needs a pH of about 7.2–7.5 or higher and manganese removal a pH of about 7.2–8.5, plus contact time (with ozone, about 10 minutes for iron). Test your water first.
