Parametric assessment of VAG prototype Final Report

Project Report: Parametric Assessment of the Original Vortical Aerosol Generator and Its Replica Assembled at PNNL

1. INTRODUCTION Under the Project PNNL T2-242 “Development of Effective Decontamination Methods and Technology” sponsored by the US DOE Global Initiatives for Proliferation Prevention (GIPP), PNNL and the Institute of Highly Pure Biopreparations (IHPBP, Saint Petersburg, Russia) have developed a non-intrusive method/technology “PAEROSOL” for concurrent decontamination/disinfection of airborne pathogens and pathogens residing on inanimate surfaces (fomites) in contained environments, such as hospitals, transportation units, farms, food processing facilities, and alike. High bactericidal efficacy of PAEROSOL has been demonstrated with significant number of different microbial cells, viruses, microbial, and fungal spores in an aerosol chamber of 100 ft3 and in the rooms of 2,000 and 3,000 ft3. PAEROSOL was shown neither toxic, nor corrosive, and no negative impact to sensitive electronics was observed during long-term practicing PAEROSOL protocol in the same room. PAEROSOL requires minimal logistics and leaves virtually no wastes after mission completion.
