In short, hydrogen peroxid is the best way to remove iron and/or sulfur from water. Hydrogen peroxide is one of the most powerful oxidizers, and is stronger than chlorine, chlorine dioxide, and potassium permanganate. Only fluorine, the hydroxyl radical and ozone are better oxidizers, but all are either deadly poison or cost prohibitive.
Not only is H2O2 a powerful oxidizer, but H2O2 is a natural metabolite of many organisms, which decompose the H2O2 they produce into oxygen and water. H2O2 is also formed by the action of sunlight on water a natural purification system for our environment. Consequently, H2O2 has none of the problems of gaseous release or chemical residues that are associated with other chemical oxidants. And since H2O2 is totally miscible with water, it reverts to hydrogen and oxygen after the reaction is complete.
Hydrogen peroxide is lethal to iron, sulfur and manganese. Complete elimination of iron and sulfur, regardless of the levels, without the use of dangerous chemicals is the paramount reason to use H2O2. It will eliminate iron and sulfur and the rotten-egg odor, even if the water contains iron and sulfur-reducing bacteria. It also has a relatively low cost, using only 20 to 40 gallons of hydrogen peroxide a year for a family of four.
I guess that is the only downside to the inFusion system: You have an annual H2O2 bill of typically $300 to $400 dollars a year… but most of our customers think that is a small price to pay for the best water this side of heaven!
