Impact/Purpose:

To evaluate a technology being developed to regenerate organic contaminant-spent GAC

Description:

Fenton-driven regeneration of spent granular activated carbon (GAC) is a technology being developed to regenerate organic contaminant-spent GAC. Here, the effect of GAC particle size (>2 mm to <0.35 mm) on Fenton-driven oxidation of methyl tert-butyl ether (MTBE)-spent GAC was evaluated. Iron (Fe) was amended to the GAC using two Fe loading methods: (1) bulk-Fe loading – where GAC was amended with a solution of ferrous sulfate; and (2) acid pre-treatment – where GAC was amended with acid followed by sequential applications of a dilute ferrous sulfate solution. Subsequently, MTBE was amended to the GAC, followed by oxidative treatments with H2O2. H2O2 reaction and MTBE oxidation were inversely correlated with GAC particle size and was attributed to shorter intraparticle diffusion transport distances for both H2O2 and MTBE. Acid pre-treatment of the GAC prior to Fe amendment improved MTBE oxidation and was attributed to greater Fe distribution within the GAC particle.
