Abstract (en)

[origin: WO2008122871A2] The invention relates to the purification of indoor air using a method that essentially comprises forcing the air to be processed to flow through an active medium exposed to a germicidal radiation in the presence of a photocatalytic material contained therein, with a destructive action on the microorganisms optionally present in the air and retained in the active medium such as reduced and/or weakened due to the impact on wall members provided therefor in the active medium. A first active medium includes a mass made in the form of a three-dimensional network of walls with photocatalytic surfaces and located in the immediate vicinity of a germicidal radiation source. A second active medium includes a liquid mass in which particles with a photocatalytic surface are dispersed and submitted to a germicidal radiation. The liquid mass is agitated by feeding air therein in order to generate a vortex.
