Abstract
The report evaluates a photocatalytic oxidation technology's ability to destroy volatile organic compounds (VOC) and other contaminants present in liquid wastes. Specifically, this report discusses performance and economic data from a Superfund Innovative Technology Evaluation (SITE) demonstration and one case study of the technology. This technology involves exposing titanium dioxide (TiO2) particles to ultraviolet (UV) light having a predominant wavelength of 254 nanometers. The TiO2 is activated by UV light to produce highly oxidizing hydroxyl radicals. Matrix also uses hydrogen peroxide and ozone to enhance the treatment system's performance. Target organic compounds are either mineralized or broken down into low molecular weight organic compounds, primarily by hydroxyl radicals. The Matrix technology was demonstrated over a 2-week period in August and September 1995 at the K-25 Site of the U.S. Department of Energy Oak Ridge Reservation in Oak Ridge, Tennessee. Potential sites for applying this technology include Superfund and other hazardous waste sites where groundwater or other liquid wastes are contaminated with organic compounds.
