In this sewage plant under consideration, the wastewater is moved vertically using eight Archimedes screw pumps. During the process of moving the wastewater upward, there is an emission of H2S from the surfaces of the Archimedes pumps. Traces of H2S have been detected inside of the building that houses the pump engines.
The present paper evaluates a modification in the HVAC system of the building to mitigate the presence of H2S inside the building.
