Abstract: A reacting canister utilizing transparent optical fiber technology coated with a photo-catalyst and a plasmonic layer, including yttrium aluminum garnet nanoparticles, disposed between the optical fiber and the photo-catalyst to degrade off-flavor compounds in aquacultured aquatic life. The degradation of off-flavored compounds—including 2-methylisoborneol—can be significantly enhanced by increasing the surface area of the catalyst. Coating individual transparent optical fibers and aligning those fibers in a canister configuration allows the treatment of large volumes of water in portable and scalable reactors. Once the fluid is treated, the fluid is returned to the reservoir containing the aquacultured aquatic life.

Abstract: A catalytic reactor using catalyst-coated optical fiber technology that will allow the control of light and its emission mode to quantitatively optimize catalytic degradation of off-flavor compounds. This degradation can be greatly enhanced by increasing the surface area of the catalyst. Coating individual transparent optical fibers and aligning them in a canister configuration allows the treatment of large volumes of water in portable and scalable reactors.
