H2Scents® - H2S Monitoring

Where’s the Rotten Egg?

Bioreactions within a collection system generate Hydrogen Sulfide (H2S) causing odors. The smell can be strong, persistent, and a nuisance to employees, residents, community leaders, and businesses located near manholes and water treatment facilities. Although the scent of H2S is a characteristic rotten egg smell, the odor isn’t a dependable indicator of H2S presence or for increasing concentrations of the gas. Yet, you can be assured community-wide complaints increase when H2S is present. H2S monitoring preserves infrastructure and prevents complaints.

Hydrogen Sulfide (H2S) is the most commonly known and prevalent odorous gas in domestic wastewater collection and treatment systems. Bioreactions within a collection system and wastewater treatment plant processes generate H2S, causing odors that can be strong, persistent, and a nuisance to employees, residents, and businesses located near manholes, pump stations and wastewater treatment facilities.

H2Scents® uses a specialized sensor designed to integrate with our proprietary software for reliable, real-time measurement of H2S levels over extended periods of time.

Damage from H2S
Our technology continuously gathers and analyzes sewer flow data. When suspicious changes are detected, public works is informed of any intake point. Over time, data from specific hotspots is used to detect unusual surges, indicating a large discharge into the sewer system. Time stamped data is tracked and used to investigate illegal entry and dumping into a collection system — saving millions of dollars in resources.

Dosing Costs Escalate
dentifying and controlling H2S levels leads to greater efficiency — operators can be more accurate with water treatment dosing, minimizing chemical use.

Asset Management
Identifying and controlling H2S levels leads to greater efficiency and efficacy — operators can be more accurate with water treatment dosing and the decreased exposure of infrastructure assets to H2S leads to longer asset life.

Advanced Warnings
Operators use SmartCover for real-time decision support for advance warning of potential issues. Not only does this make an operator’s job easier, it offers significant public benefits by reducing the possibility of annoying smells wafting through local neighborhoods.
