There is a need for an alternative treatment process for the removal of methyl tert-butyl ether (MTBE)
and tert-butyl alcohol (TBA) from contaminated waters. Advanced oxidation processes (AOPs), which
involve the application of various combinations of ozone (O<sub>3</sub>), hydrogen peroxide(H<sub>2</sub>O<sub>2</sub>), ultraviolet light (UV), and semi-conductors (e.g. TiO<sub>2</sub>), provide promising
treatment options. The major advantage of AOPs is attributed to hydroxyl radical
(OH.) which attacks indiscriminately almost any organic compounds with very high
reaction rate constants. In addition, the OH. oxidizes a wide variety of organic
pollutants into innocuous intermediates and end products, as opposed to conventional
treatment methods, such as activated carbon and air stripping, in which pollutants are
transferred from water to another medium that may need further treatment before final
disposal.
The main objective of this study is to investigate application of ozone/UV process for
the removal of MTBE and TBA in dilute aqueous solution under different operational
conditions, i.e., ozone gas dosage, incident UV light intensity, and water quality in
terms of bicarbonate concentration, and at the same time identify byproducts formed. Includes 14 references, figures.
