  • Soil and sediment remediation
    Patent number: 10124378
    Abstract: A batch process of remediation of soil and sediment contaminated with toxic metals includes the steps of treating contaminated soil and sediment with a solution containing aminopolycarboxylic chelating agent, rinsing the soil/sediment solid phase to remove residues of mobilized toxic metals, treating the used process waters to recycle chelating agent and clean process solutions and placing the remediated soil/sediment on a permeable horizontal reactive barrier to prevent emission of contaminants. In the batch process, toxic metals are removed from process solutions by alkaline adsorption of polysaccharide adsorbents. By applying alkaline adsorption the efficiency of toxic metal removal from process solutions and alkaline and acidic recycling of chelating agent is significantly improved.
