Measuring Hydrogen Sulfide in ,Wastewater,. ,Wastewater treatment, costs can be reduced if pipelines are protected from corrosion due to rising sulfide loading and if the injection of chlorine (to break down H 2 S) can be optimized. Since the pH of the water determines how much of the H 2 S is presently dissociated to ions, additional measurement of the ions would provide a much …
