The widespread use of methyl t-butyl ether (MTBE) in gasoline has resulted in
groundwater contamination. Because leaking underground storage tanks are the major
sources, advanced oxidation processes (ozone/hydrogen peroxide) are very effective
for removing these constituents. A system designed by Applied Process Technology
to remove MTBE woks very well however resulted in higher than normal acetone effluent
levels. West General designed a biorector to remove the excess acetone from the
HiPOx system effluent, a reduction of over 90%!
