EUROCHAMP-2020 worked with the Anglo Italian company U-earth Biotech Ltd to test four prototypes of a biological air treatment device (“AIRcel”) and analyse the response when used against a diverse range of air pollutants. The prototypes were sent to the HELIOS simulation chamber one month before the campaign started, to give time to the biomass to adhere to the support and form the active biofilm. AIRcel abatement capacity was tested with a wide range of pollutants: acetone, sulphur dioxide, nitrogen oxides (nitrogen oxides and nitrogen dioxide), toluene, benzene, limonene, and methane. The tests were performed with standard and modified AIRcel configuration.
