Hydrogen Sulfide (H2S) formation in sewer systems is a well-documented problem. It is a gas, which when released from the wastewater, can cause problems in asset degradation, human health and safety, and odor problems that influence liability in cities.
The data|APX® platform helps utilities with their hydrogen sulfide problems through a dedicated analysis module. Using available data from the utility and through an empirical model for calculating hydrogen sulfide formation, it provides a complete and dynamic overview of the potential hydrogen sulfide challenges in the utility’s sewer system. This is used in the initial identification and prioritization of problematic sites.
- Dynamic overview of the potential hydrogen challenges in the utility’s sewer system
- Identify and prioritize problematic sites
- Complete the elimination of the hydrogen sulfide problem as observed in the data|APX® platform interface.
Our H2S analysis module integrates to market available H2S sensors, one being the SulfiLogger sensor from Unisense. Combining dynamic data modelling and real-time sensor data provides the utility with a unique solution for optimizing the identification of potential H2S threats.
One specific example of use is the city of Struer where the local utility, Struer Forsyning, identified a potentially problematic branched force main south of the city Struer. Using the continuous sensor signal from these installations, Struer Forsyning optimized the dosing rate used in the existing chemical mitigation strategy to match the actual H2S levels resulting in a complete elimination of the hydrogen sulfide problem as observed in the data|APX® platform interface.
