Case study Liquid-phase H2S sensor provides new insights at treatment plants Despite causing severe odor, corrosion, and worker safety issues, H2S is still a neglected process parameter at wastewater treatment plants (WWTPs). This case study examines how two of Veolia's French subsidiaries; Klearios and Société des Eaux de Marseille (SEM), gained new insights into the H2S challenges at two WWTPs. These insights were obtained using a novel sensor for permanent and real-time monitoring of H2S in untreated sewage. Download this case as a PDF Background H2S is a major challenge [...]

Case study New sensor provides better H2S insights in sewer networks This case study shows that a new sensor technology provides better insights into how hydrogen sulfide impacts sewer networks by continuously measuring H2S directly in or just above untreated wastewater. This new approach to H2S monitoring delivers true and reliable data that allow wastewater utilities to manage and optimize H2S mitigation activities on a fully informed basis. Download this case as a PDF Background The toxic, foul-smelling, and highly corrosive gas hydrogen sulfide (H2S) poses a major challenge [...]
