Crossflow Air Stripping with Catalytic Oxidation

Abstract

A novel air stripping technique was tested on a pilot scale at Dover Air Force Base. Groundwater contaminated with 1,2-dichloroethane was subjected to air stripping in two towers: the novel crossflow tower and the conventional countercurrent tower. The crossflow tower was found to require higher airflow rates but much lower pressure drops to effect the same removal efficiency. The airstream from the towers was directed into bench-scale and pilot-scale commercial catalytic units. An innovative photocatalytic unit also was tested. Five of the six catalysts tested performed well. Air stripping in conjunction with catalytic oxidation was found to be a good technique for remediation of groundwater containing low levels of organics. However the crossflow air stripper did not offer any cost advantages over conventional counterflow air stripping.
