Advanced oxidation process used at a former ordnance plant

Abstract

"Advanced oxidation processes (AOPs) allow treatment of contaminated water through dark and light processes. The dark processes use ultraviolet light (UV) with chemical reactions and the light processes use just chemical reactions. The technology is traditionally used as a pretreatment system with an AOP reactor vessel. The bench-scale AOP study performed at the former Nebraska Ordnance Plant was used to show that an existing pipeline transporting contaminated groundwater could act as the reactor vessel. The existing pipeline is six miles long and connects two remedial action wells (EWs), EW-8 and EW-11, to an on-site water treatment plant. The six-mile pipeline’s hydraulic retention time is theoretically sufficient for all chemical reactions related to the AOP technology to occur.

The bench-scale study was used to evaluate the use of an existing six-mile pipeline as an effective reactor vessel for the pretreatment of groundwater contaminated with trichloroethylene (TCE) using an AOP known as peroxone. Peroxone uses hydrogen peroxide and ozone to form a hydroxyl radical which degrades the TCE in the groundwater. The study consisted of three phases. Phase I characterized the optimum peroxone dosage for a constant flowrate. Phase II of the bench-scale study characterized the treatment efficiency of peroxone with respect to variable flowrates. Finally, Phase III was a batch reactor study conducted to characterize AOP scavenger effect, if any, on granular activated carbon (GAC) for peroxone pretreated water versus non-peroxone pretreated water"-- Abstract, p. iv
