This paper discusses a study that was conducted with five contaminated groundwaters on the treatability of methyl tertiary-butyl ether (MTBE) via air stripping, carbon adsorption, UV/H2O2 and O3/H2O2 using an experimental water treatment pilot plant. In this study, key design parameters were experimentally determined and used to estimate treatment costs for each process under a variety of water quality and process conditions. The study showed that each process can be effective under specific conditions although unit treatment costs varied widely. In general, air stripping was most economical for high flowrates at the process conditions. The O3/H2O2 advanced oxidation was the most economical process at low flowrates for some of the groundwaters, although it was ineffective at MTBE removal in one high chemical oxygen demand (COD) groundwater. While neither UV/H2O2 or granular activated carbon (GAC) sorption were the least expensive option at a specific set of conditions, each were competitive at low flow for selected waters. Includes 8 references, tables, figures.
