Smart ventilation system optimisation for wastewater treatment plants, with improved energy efficiency.

Odour formation and emission associated with wastewater treatment can vary, depending on several operating and environmental conditions, such as temperature. During the warmer season, higher odour pollutant concentrations can be observed, especially for hydrogen sulphide. Nonetheless, ventilations systems at wastewater treatment plants have typically constant operating regimes, and are not adapted to these variable conditions.

During the project OptimOdour – Smart optimization of wastewater treatment plant ventilation systems – funded by the Portugal 2020 Research and Technological Development Scheme (Ref. 2015/3357), a software was developed to manage and control the ventilation systems, supported on real time pollutant monitoring.
