Description:
This Bulletin is a brief description of the AIR2000 technology developed by KSE, Inc., of Amherst, MA. The AIR2000 unit treats air streams containing volatile organic compounds (VOCs). The demonstration occurred at the Stamina Mills superfund site in North Smithfield, RI from August-October 1999.
In the AIR2000 technology, a contaminated air stream flows into a photocatalytic reactor where the VOCs are adsorbed onto the surface of a proprietary catalytic adsorbent that is continuously illuminated with ultraviolet light. The ultraviolet light destroys the adsorbed, concentrated VOCs through enhanced photocatalytic oxidation. KSE claims that the AIR2000 process offers advantages over other photocatalytic technologies because of the high activity, stability, and selectivity of the photocatalyst. Analytical results compiled prior to the SITE demonstration indicate that the photocatalyst is highly resistant to deactivation, even after thousands of hours of operation in the field.
