BIOFILTRATION OF WASTEWATER TREATMENT FACILITIES The Tennessee Valley Authority (TVA) is considering offering rights for exclusive license(s) to make and sell biofilters utilizing TVA-developed proprietary techniques and know-how for the control of odors in wastewater treatment facilities. The grant of such license(s) will be subject to TVA's reservation of a license on behalf of the U.S. Government to make or have made, use, practice and have practiced the invention. For exclusive licenses, the period contemplated for exclusivity is 8 years. Consideration will also be given to several exclusive licenses based on geographic areas. This technology utilizes selected microorganisms immobilized on a solid support matrix. As the odor compounds pass through the filter bed, pollutants are oxidized, forming carbon dioxide, water and salts. Parties interested in this technology should submit in writing a notification of interest within 30 days of this notice to W. Keith Rylant, Tennessee Valley Authority, Post Office Box 1010, CTR 1L, Muscle Shoals, Alabama 35662-1010. Posted 05/25/99 (W-SN335630).
