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 H2S) can be optimized. Since the pH of the water determines how much of the H2S is presently dissociated to ions, additional measurement of the ions would provide a much more accurate reading of sulfide loading in the water.

The OMA system applies the power of dispersive UV-Vis absorbance spectroscopy to this analysis. Water has no absorbance in the ultraviolet range so the process background is completely transparent to this system's signal. The full-spectrum 200-800nm acquisition is critical for isolating the absorbance curves of each analyte in the water.

Applied Analytics is the industry leader in real-time analysis of multiple sulfur compounds. We utilize this expertise to measure H2S and its ions simultaneously in the water to produce a measurement with zero dependence on pH, thus providing a proven analytical solution for water streams where other analyzers have failed.
