Impact/Purpose:
To determine if Fenton-driven regeneration of spent granular activated carbon (GAC) is a technology that may be able to reduce water treatment costs
Description:
Fenton-driven regeneration of spent granular activated carbon (GAC) is a developing technology that may reduce water treatment costs. In this study, the effect of GAC particle size on Fenton-driven oxidation of methyl tert-butyl ether (MTBE)-spent GAC was evaluated. The GAC was sieved to create several particle size fractions (<0.35 to >2 mm) and iron (Fe) was loaded onto the GAC using two Fe loading methods. Bulk Fe loading involved the application of a ferrous Fe solution to the GAC. Acid pre-treatment of the GAC was performed before sequential Fe amendment to enhance Fe distribution in the GAC. Subsequently, MTBE was amended to the GAC, followed by oxidative treatments with H2O2. The H2O2 degradation rate and the extent of MTBE oxidation were inversely correlated with GAC particle size, increasing as size decreased. Acid pre-treatment of the GAC followed by Fe amendment resulted in significantly greater MTBE oxidation. Overall, results indicate that MTBE removal and GAC regeneration increases as particle size decreases and with acid pre treatment.
