Chao Zhou to Present on Metabolic Biofiltration of 1,4-Dioxane at the 2020 International Symposium on Biological Treatment.
Chao Zhou, P.E. (California) will present "Bench Testing of Metabolic Biofiltration of 1,4-Dioxane in Drinking Water" at the American Water Works Association's (AWWA's) 2020 International Symposium on Biological Treatment at the W Atlanta Downtown in Atlanta, Georgia at 4:00 p.m. on February 12, 2020.
Chao's coauthor is Brian Petty, P.E., Geosyntec.
Chao is an Engineer based in California focused on performing and managing evaluations of water and wastewater treatment technologies (physical/chemical and biological), feasibility studies, treatability studies, and process design. Over the years, he has expanded his practice area to construction quality assurance and Operations and Maintenance (O&M) optimization. He is also one of the technical leaders within Geosyntec in applied research and development in innovative biological treatment/bioremediation of emerging contaminants, such as 1,4-dioxane.
AWWA is an international, nonprofit, scientific and educational society dedicated to providing total water solutions assuring the effective management of water. Founded in 1881, the Association is the largest organization of water supply professionals in the world. AWWA also helped establish two preeminent organizations dedicated to safe water, the Water Research Foundation in 1966 and Water For People in 1991. AWWA unites the diverse water community to advance public health, safety, the economy, and the environment.
1,4-dioxane is a synthetic chemical used in a variety of industries and produced as a byproduct or impurity in household and industrial products. It was detected above 0.35 µg/L (the 10-6 cancer risk level) in approximately 7% of the drinking water systems during the USEPA's Third Unregulated Contaminant Monitoring Rule (UCMR3), the second highest exceedance frequency among the contaminants monitored in UCRM3. The only effective treatment technology is the advanced oxidation process (AOP). The industry (particularly small systems in rural areas) needs an alternative treatment technology and this presentation will describe the proof of concept for metabolic treatment of 1,4-dioxane in drinking water by biofiltration.
