Abstract
An adsorbent electrode assembly electrically enhances contaminant removal in soil washing processes. The adsorbent electrode assembly is immersed in the froth of a flotation cell and connected to one pole of a battery. The other pole of the battery is connected to the flotation cell tank. The resulting electric charge (either positive or negative depending on the nature of the contaminant) applied to the adsorbent electrode assembly attracts contaminants in the froth to the adsorbent electrode assembly which adsorbs them. The adsorbent electrode assembly is then easily removed from the cell for replacement or regeneration. The adsorbent electrode assembly can comprise one or more carbon rods, a carbon screen, or a porous bag filled with an adsorbent material and having an electrode disposed therein.
