Hydrogen Sulfide (H2S) causes severe problems in wastewater collection and treatment 
plants. Equipment corrosion, odor complaints, and operator/public safety are some of the issues routinely encountered with H2S. Chemical dosing is typically used to control H2S, but to better manage facilities and optimize mitigation practices, utilities need more information to understand how H2S behaves throughout the sewer networks and facilities over time. 
New H2S sensor technologies enable operators to continuously measure H2S in both liquid and gas phases in collections systems and treatment plants. Through their installation, they give a complete and dynamic overview of H2S impacts, providing a path to proactive and data-driven approaches to H2S management. Trends and trouble-spots can be identified before they become problems. The result ofthis is optimized chemical dosing, minimized odor complaints, prevention of equipment corrosion and premature equipment failure, and protection operator and public safety. 
These probes are robust, ClDl rated, and can operate in remote locations. They are easily cleaned, maintained, and simple to calibrate. Importantly, their successful operation has been proven with multiple case studies documenting their efficacy.
