Gifford, Mac Selvy, Ashley Gerrity, Daniel Optimizing Ozone-Biofiltration Systems for Organic Carbon Removal in Potable Reuse Applications <p>This study presents a framework for simultaneously evaluating ozone dose and empty bed contact time in ozone-biofiltration systems when aiming to optimize or maximize total organic carbon (TOC) removal in potable reuse applications. Ozone:TOC ratios of 0.35, 0.62, and 1.12 resulted in ΔTOC<sub>max</sub> values of 17–19%, 21–24%, and 26–30%, respectively, during pilot scale biofiltration with anthracite or biological activated carbon. The corresponding first-order rate constant for the biodegradation of TOC was similar for both media types (0.25 ± 0.06 min<sup>−1</sup>). In addition to bulk organic transformation, ozone was effective in reducing the concentrations of many trace organic compounds.</p> Biofiltration;biological activated carbon (BAC);Ozone;potable reuse;total organic carbon (TOC);trace organic compound (TOC) 2018-08-27
