Abstract

Systems and processes for treating a contaminated aqueous flow which includes contaminants, such as munitions contaminants including metallic contaminants, energetic material contaminants, and/or propellant contaminants, are disclosed. The systems include an adsorption layer which includes bone char particulates, titanium dioxide particulates and/or aluminum oxide particulates which promotes adsorption of the contaminants upon contact of the contaminated stream and the adsorption layer so as to produce a treated aqueous flow, which is depleted in the munitions contaminants. Optionally, the adsorption layer can be buried in granulates particles so the contaminated aqueous water can percolate down through the earth and towards the adsorption layer, so the treated water can further percolate through the earth. The system can alternatively include more than one adsorption layer, which can be arranged in series or in parallel, in situ or ex situ.
