Treatment of methyl tertiary-butyl ether (MTBE) from=20 contaminated surface and ground water supplies presents specific = challenges due=20 to the physicochemical properties of MTBE that depend strongly on its=20 hydrophilic nature, and translate into a high solubility in water, and = low=20 Henry's constant and low affinity for common adsorbents. We evaluate = four=20 treatment technologies-air stripping, granular activated carbon (GAC),=20 hydrophobic hollow fiber membranes, and advanced oxidation processes = (AOP)-using=20 ozone or ozone/hydrogen peroxide. Experimental work was carried out to = generate=20 parameter values necessary for the design of these processes. Ten = different flow=20 rates/concentration combinations were evaluated in our designs to cover = the=20 range from high flow rate/low concentration typical of surface water and = ground=20 water drinking water supplies to low flow rate/high concentration = typical of=20 ground water remediation sites. For all cases, the processes were = designed to=20 produce effluent water of 5 g/L or=20 less. Capital costs and operation and maintenance costs were determined = at the=20 feasibility level by using standard engineering estimating practices. = Air=20 stripping is the lowest cost technology for high flow rates (100 to 1000 = gpm) if=20 no air treatment is required. Hollow fiber membranes are the lowest cost = technology for flow rates of 10 to 100 gpm if no air treatment is = required,=20 which is typical at these low flow rates. GAC will be most costeffective = at all=20 flow rates if air treatmentis required and the influent water has low = levels of=20 other organic compounds. AOP using ozone or ozone/hydrogen peroxide is = in all=20 cases more expensive than the alternative technologies, and there are = sufficient=20 uncertainties at this point with respect to byproducts of AOP to warrant = further=20 study of this technology. The cost of treating MTBE-contaminated water = for=20 conventional technologies such as air stripping and GAC is 40% to 80% = higher=20 than treating water contaminated only with other hydrocarbons such as = benzene.=20 [Journal Review; 62 Refs; In English; Summary in English]
