Summary
In wastewater management, hydrogen sulfide (H₂S) is a familiar threat—linked to odor complaints, corrosion, and safety risks. But are you looking in the right place?
Most monitoring focuses on the gas phase, where readings are influenced by ventilation, turbulence, and sensor placement. But H₂S is born in the liquid phase—and that’s where the real story begins. Liquid phase monitoring allows you to detect sulfide activity at its source, enabling earlier insights and more effective control strategies.
Watch a practical, application-focused session where we’ll explore how liquid phase H₂S measurement with the GSX440 gives you a clearer, earlier, and more actionable view of what’s happening in your network or plant.
Learning Objectives
- Why gas-phase monitoring often misses the bigger picture
- How liquid-phase measurement reveals hidden risks and upstream sources
- Real-world use cases: from rising mains to buffer tanks and WWTP influents
- How to optimize reagent dosing and validate mitigation strategies in real time
Who is this webinar for
Operators, engineers, and decision-makers in municipal and industrial wastewater treatment who want to move from reactive to proactive H2S management—and finally see what’s really happening below the surface.
