1,4-DIOXANE BIO-DEGRADATION BENCH STUDY AT THE LOWRY LANDFILL SUPERFUND SITE

Abstract

Groundwaters from the Lowry Landfill Superfund Site, Aurora, CO, have been treated using a UV catalyzed hydrogen peroxide advanced oxidation process, which has had difficulty removing 1,4-dioxane to low levels due to UV absorbance by the waters. Parsons performed a bench study to investigate biological degradation of the target compound. Parsons ran up to seven bench scale conventional activated sludge systems over six months, testing a variety of feed mixtures, loading rates, and sludge retention times. Parsons showed that 1,4-dioxane is amenable to biological treatment, with removals below the detection limit at several operating conditions.
