Photocatalytic Air Disinfection to Destroy
Airborne Hazardous Microorganisms
The biggest danger from biohazards, such as anthrax, comes when
they become airborne and spread through the building ventilation
system. Conventional air filtrations systems are inadequate to
provide a satisfactory solution. Drastic measures, such as fumigation
with Chlorine Dioxide, have serious consequences. Photocatalytic
disinfection technology developed by Dr. Goswami has been shown
to be effective, however, the technology needs improvement to be
effective against bioterrorism. It is proposed to improve the
photocatalytic air disinfection technology to reduce the time needed
for complete oxidation to a fraction of a second. The improved
photocatalytic technology incorporated with HEPA and electrostatic
air filters will provide complete solution to removing and neutralizing
biohazards from indoor air. The proposed improvements will include
active removal electrons from the catalytic surface, thereby improving
the reaction rate, and identifying catalysts that may utilize visible light
for activation.
