Sulfide odor control within sanitary sewers has been practiced for over 50 years, yet only recently have substantive advances been made. Where once the choice of chemical treatment was either chlorine or iron salts, safer and more environmentally benign technologies based on nitrates, hydrogen peroxide, and/or magnesium hydroxide have gained acceptance. These new alternatives, however, can increase treatment costs substantially and present limitations in themselves. Therefore, it makes sense to explore new avenues for lessening the adverse impacts of the older, cheaper mainstays, particularly iron salts (ferrous/ferric chloride or sulfate) that provide other benefits to wastewater treatment operations.
