| dc.description.abstract | A technical evaluation of a capability to treat and/or recycle the effluent from the Army’s aqueous based chemical, biological, radiological and nuclear (CBRN) decontamination operations was conducted on 26–28 June 2017 at the U.S. Army Engineer Research and Development Center (ERDC) Waterways Experiment Station (WES), 3909 Halls Ferry Rd, Vicksburg, MS. The Decontamination Effluent Treatment System (DETS) is a reactor system specifically designed to address decontamination effluent. The objectives of the evaluation were to show an ability to reduce chemical hazards, reduce logistical burdens, and eliminate possible political impacts. The DETS is a fully functional system designed to treat waters containing contaminants, minimize decontamination water requirements, be rapidly deployable and easy to maintain, while minimizing the volume of decontamination waste requiring management/disposal. The field evaluation consisted of a simulation of vehicle decontamination followed by on-site treatment of the resulting effluent water. | en_US |
