Pilot-scale devices for remediation of munitions contaminated soils


, : Pilot-scale devices for remediation of munitions contaminated soils. Journal of Environmental Science & Health Part A Toxic-Hazardous Substances & Environmental Engineering 33(8): 1515-1531, Nov

An equipment is described for the remediation of (TNT) contaminated soil in pilot scale setting. Devices were developed for the preparation of soil samples and for the removal of water from soil after treatment of a soil slurry in a 60 L air-lift reactor, which was a prototype of larger commercial unit. The method was applied to clean up TNT-polluted soil using Fenton reagent (H2O2 + Fe2+) as remedial technology. Pilot scale results were compared to those obtained at bench scale level. Laboratory scale experiments showed that 1% H2O2 + 640 mg Fe2+ L-1 reduced TNT concentration from 400 mg kg-1 to about 50 mg kg-1, which was above the Nebraska Ordnance Plant's cleanup goal (17.2 mg TNT kg-1). Adding the reagent incrementally rather than in a single dose was more effective in reducing TNT concentration at both bench and pilot scale. Faster removal of TNT was obtained in the pilot reactor: TNT concentration fell within 24 h below the clean-up goal and less cumulative amount of H2O2 (0.625%) was required. The designed sieve size device provided reliable and rapid screening of contaminated soil to a sieve size (1 mm) optimal for reactor performance. The vacuum filter effectively separated water and soil from soil slurry, reducing handling and processing of primary residuals.
