This study evaluates a push-pull ventilation system with localized extraction designed to reduce H2S concentrations in the settling stage of a wastewater treatment plant in Santiago, Chile.
CFD simulations and field measurements show that the existing crossed ventilation system results in H2S concentrations up to 21 mg/m³ over the water surface. The improved push-pull system effectively lowers H2S levels in the plant corridors to below 7.5 ppm, complying with Chilean regulations.
