Description

Effective odour control management in sewer networks remains a challenge for wastewater utilities due to the limitations of existing H₂S monitoring technologies. While traditional gas-phase H₂S sensors excel at detecting local odour incidents in wells or manholes, the reliability of their readings is impacted by factors such as flow dynamics, turbulence, and ventilation. Furthermore, these sensors provide only local measurements, detecting the degassed fraction of H₂S rather than the dissolved fraction carried within the sewage. As a result, they fail to capture the full downstream odour potential of a sewer line, restricting the scope of odour control strategies that can be implemented.

This presentation will explore the concept of liquid-phase H₂S measurements as a promising alternative to gas-phase measurements. We will show how utilities can achieve a more comprehensive understanding of potential odour releases through continuous, liquid phase measurements. This approach is supported by data from a comparative sensor mapping campaign conducted in collaboration with a major utility. The findings demonstrate that liquid-phase measurements offer a more detailed perspective on H₂S challenges, enabling utilities to implement proactive and more effective odour control strategies.
