Hettich EBA 20 Tabletop Centrifuge Used in Photocatalytic Process to Eliminate MTBE from Gasoline-Contaminated Water

Hettich EBA 20 Tabletop Centrifuge Used in Photocatalytic Process to Eliminate MTBE from Gasoline-Contaminated Water

The Hettich EBA 20 tabletop centrifuge was used in the study “Application of Photocatalytic Process for Removal of Methyl Tert-Butyl Ether from Highly Contaminated Water” by the Department of Environmental Health Engineering of the University of Tehran.

Methyl tert-butyl ether (MTBE) is added to gasoline to boost octane levels and to decrease carbon monoxide and hydrocarbon emissions. Unfortunately, MTBE is also resistant to natural attenuation and is, according to the US Environmental Protection Agency, a suspected human carcinogen. When gasoline leaks from transportation pipes and storage tanks, MBTE contaminates local water. Researchers sought to develop an efficient method for MTBE removal.

The study notes that conventional treatments for MTBE removal have been inefficient and unsatisfactory. However, advanced oxidation processes (AOPs), in particular photocatalytic degradation, are promising methods. TiO2 is one such photocatalyst, obtained from suspensions via centrifugation with the Hettich EBA 20.

Scientists analyzed the degradation of aqueous MTBE at reasonable elevated amounts using a UV/-vis/TiO2/H2O2photocatalytic process. Ultimately, “the data presented in this paper clearly indicated that UV/-vis/TiO2/H2O2as an advanced oxidation process provides an efficient treatment alternative for the remediation of MTBE contaminated waters.”

Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on new, moreefficient methods for MTBE removal. The Hettich EBA 20 is a compact, quiet, safe and reliable centrifuge that is suitable for clinical testing and research in many fields.
