Contaminated soil cleaning device

摘要

The soil cleaning device uses a washing container (1) with a filter base (2) inserted in a cleaning fluid circulation path (3). The cleaning fluid is provided by water with added cleansing agents for removing heavy metal or organic contaminants, fed to the washing container at the base and removed at the top. Pref. the flow velocity of the cleaning fluid through the washing container is sufficient to provide a floating bed within the container, with a pulsation movement pref. superimposed on the circulation movement.
