In Sanitary wastewater collection, conveyance, and treatment system, the existence of hydrogen sulfide (H2S) can develop serious problems. These include corrosion, toxicity, and noxious odors. In normal course, corrosion control, corrosion repair, and odor control can cost billions of dollars per year. Hydrogen sulfide can be treated in vapor phase or in the liquid phase using several methods, such as addition of caustic, hydrogen peroxide, chlorine, ferrous sulfate and ferric chloride, or nitrate. Yet the capital investment for such methods are estimated to be more than $50,000 per treatment site
