AN ADVANCED OXIDATION PROCESS:
Simplicity of operation is the mark of the KSE photocatalytic Adsorption-Integrated-Reaction (AIR) Process. Air streams contaminated with chlorinated hydrocarbons, alcohols, or other volatile organic compounds are emitted from manufacturing plants or remediation sites. The contaminated air stream enters the AIR reactor where the contaminants are trapped on the surface of a new, proprietary catalytic adsorbent. In the presence of ultraviolet light, the adsorbed contaminants are catalytically destroyed to form environmentally safe products. Oxygen in the air is the only reactant.
The AIR process has broken through barriers that have historically impeded the use of photocatalytic technology for emissions control. The AIR catalyst is highly active, providing orders of magnitude more activity, exceptional selectivity, and markedly lower power consumption, achieving operations which are safe, simple and economical to own, operate, and maintain.
UNEQUALED PERFORMANCE:
The AIR Process has clear advantages over alternative air emissions control options. It has been demonstrated to achieve up to 99+% destruction efficiency in field tests. It completely destroys the contaminants, avoiding the production of secondary wastes as in activated carbon treatment. The use of UV light bulbs to photocatalytically destroy pollutants provides extremely simple controls. The unit can be turned on or off with the flip of a light switch. The ambient operating temperatures result in low energy consumption, enables location of pollution control units at sites with potentially flammable concentration of VOCs, and provides low cost. For example, the ambient temperature AIR unit can be constructed of fiberglass reinforced plastic, rather then the expensive exotic alloys used in alternative high temperature technologies.
PROVEN TECHNOLOGY:
The KSE AIR Process has been successfully field demonstrated at full scale to control tetrachloroethylene (PERC) emissions from a soil vapor extraction operation at Loring Air Force Base (AFB) in Maine. The demonstration was an element of the EPA Superfund Innovative Technology Evaluation (SITE) Emerging Technology Program (ETP), with operational guidance and support of EPA Region 1 and the EPA New England Office of Site Remediation and Restoration. Through independent laboratory evaluations, the unit achieved 99+% destruction of contaminants, with demonstrated destruction only to environmentally benign compounds.
Another field demonstration was successfully completed at the Dover AFB Groundwater Reclamation Site. Dichloroethane contained in the air emitted from a groundwater stripper was demonstrated to be successfully destroyed by the AIR Process. The field program was conducted by Battelle Memorial Institute, Columbus, under contract to the U.S. Air Force. The unit met all performance specifications, and the AIR photocatalyst showed no deactiviation during thousands of hours of continuous operation.
WHY THE AIR PHOTOCATALYST IS UNIQUE:
KSE, Inc. has been developing scientific and commercial studies of catalysis for nearly 20 years. The role of ultraviolet (UV) light in photocatalysis adds a very important new dimension to the classic variables of catalyst synthesis and reactor design. All these advanced concepts are exploited in the AIR Process.
Many researchers are exploring photocatalysis, using variations of a titania catalyst. Although a useful photocatalyst may comprise titania along with other semiconductors, it is unlikely to consist solely of titania. Researchers have now embarked upon the important mission of exploiting the combinations of titania with other materials which will form the commercial basis for photocatalysis in coming decades.
 ADVANCED APPLICATIONS:
Under contract to NASA, the AIR Process has been developed for air revitalization in life support systems during extended space operations. Maintenance of ethylene levels in the ppb range in plant growth facilities is essential to successful implementation of a Controlled Ecological Life Support System (CELSS) which relies on the growth of healthy plants for space missions. KSE is preparing to provide a photocatalytic ethylene scrubber for the continual removal of ethylene from space-based plant growth systems. This technology has been used for ethylene air pollution control in the International Space Station.
