Hydrogen peroxide oxidation/sterilization/filtration system for commercial facility in South Texas. Hydrogen peroxide oxidizes/precipitates iron, manganese and H2S gas while sterilizing all anaerobic bacteria including sulfate reducing bacteria that cause that horrible odor in your water, and leaves zero toxic residuals like chlorine does (THM's). A small residual amount of hydrogen peroxide in the water can be very beneficial or it can be completely removed using catalytic carbon. This particular water well had slight iron and H2S gas, typical for South Texas. Water treated with hydrogen peroxide runs through zeolite/carbon filter. The result is iron-free, odor-free and bacteria-free water. Hydrogen peroxide does not fix "everything", but it does oxidize anything that is sensitive to oxygen. Arsenic III, for example, oxidizes to Arsenic V. If dissolved iron exists in the water, it also oxidizes from Fe+2 to Fe+3 and attracts the Arsenic V, so when you catch the iron you also catch the arsenic. If no iron exists then the Arsenic V may be run through an anion exchange softener with special media or an arsenic filter that utilizes iron oxide. Whatever the case, the Arsenic III must be oxidized to Arsenic V before it can be filtered out. Calcium is not sensitive to oxygen but dissolved carbon is sensitive to oxygen, so if dissolved carbon (CO2) exists in the water then a carbonate (CO3) is formed when oxygen is released into the water which attracts the calcium to it. The calcium carbonate (CaCO3) will then drop out but the amount is dependent upon how much carbon is in the water. Once all the carbon is oxidized and exhausted, the remaining calcium remains dissolved and will not precipitate until it is exposed to atmospheric carbon dioxide. In other words, no more buildup in the lines or in the water heater. Hydrogen peroxide is a very effective, versatile and environmentally friendly alternative to sodium hypochlorite (bleach) but like everything else, the question is not "what" but "what and how much" regarding the contaminants in your water.
