Why use hydrogen peroxide in your water/wastewater system?

H₂O₂ is Widely Used

Since it was first commercialized in the 1800’s, hydrogen peroxide production has now grown to over a billion pounds per year (as 100%). In addition to pollution control, hydrogen peroxide is used to bleach textiles and paper products, and to manufacture or process foods, minerals, petrochemicals, and consumer products (detergents). Its use for pollution control parallels those of the movement itself — municipal wastewater applications in the 1970’s; industrial waste/wastewater applications in the 1980’s; and more recently, air applications in the 1990’s. Today, hydrogen peroxide is readily available throughout the U.S. in drum, tote, mini-bulk, and bulk quantities in a variety of concentrations.

H₂O₂ is Powerful

It is one of the most powerful oxidizers known — stronger than chlorine, chlorine dioxide, and potassium permanganate. And through catalysis, H₂O₂ can be converted into hydroxyl radicals (•OH) with reactivity second only to fluorine.

H₂O₂ is Safe

Despite its power, 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, the issue of safety is one of concentration. Industrial strength H₂O₂ is a strong oxidizer and as such requires special handling precautions.

H₂O₂ is Versatile

The fact that hydrogen peroxide is used for seemingly converse applications proves its versatility. For example, it can inhibit microbial growth (as in the biofouling of water circuits) and encourage microbial growth (as in the bioremediation of contaminated groundwaters and soils). Similarly, it can treat both easy-to-oxidize pollutants (iron and sulfides) and difficult to oxidize pollutants (solvents, gasolines and pesticides).

H₂O₂ is Selective

The reason why H2O2 can be used for such diverse applications is the different ways in which its power can be directed — termed selectivity. By simply adjusting the conditions of the reaction (e.g., pH, temperature, dose, reaction time, and/or catalyst addition), H₂O₂ can often be made to oxidize one pollutant over another, or even to favor different oxidation products from the same pollutant.
