Quality of life is entirely linked to air quality around us, whether inside or outside a building. Therefore, it is not surprising that the owners and occupants of certain spaces pay attention to the air quality, especially when they work or are close to a wastewater treatment plant. The aims of this work are to diagnose the existing situation in ventilation and deodorization system of covered wastewater treatment plant and to suggest changes to improve indoor air quality and make the operation of this system more reliable and economical. The ventilation system, consisting of 10 air handling units, supply 230.000 m3/h, where some ventilation lines have 250 m. The system’s optimization solution, as well as the two new centrifugal fans implementation, with speed variation, allow a reduction in the total fans power to 60 kW and increase the energy efficiency in 60 %.
