ArenA test location for spread and filtering of aerosols

The project investigates how aerosols, possibly carrying the corona virus, spread inside sports accommodations. Tests are being carried out in the Johan Cruijff ArenA and sports centers CTO Papendal and The Hague and Maaspoort Sports and Events.

The measurements in the Johan Cruijff ArenA will first be performed without audience, using artificial aerosol generators on the stands. These generators will disperse aerosol amounts similar to enthusiastic football supporters. Between the generators, 184 aerosol particle sensors are mounted to provide insight into the spreading of the small saliva aerosols.

Finally, large-scale air cleaning systems will be employed to analyze to what extent the aerosols can be removed from the stadium air with systems that combine cold plasma, glass fiber, electrostatic precipitation and active carbon and that are placed next to the seat rows. Dependent on permission by the Dutch authorities, TU/e, Johan Cruijff ArenA, Plasmamade and Ajax also want to test with a real-life audience of spectators. They hope these tests can be performed in January.
