Need
The Arazuri wastewater treatment plant (WWTP), managed by the Mancomunidad de la Comarca de Pamplona, expressed their interest in knowing the critical points where odour episodes could occur due to high levels of H2S.
To this end, it was decided to implement a system for measuring environmental variables to improve decision-making in order to reduce the impact that odour episodes could have on nearby populations.
A study was carried out at different locations using an air quality monitoring system capable of detecting diffuse emissions of gases such as H2S and establishing the most appropriate arrangement of the sensor network based on the areas with the greatest potential for odour problems.
