System and method for remediating soil

Abstract

A method of feeding a contaminated soil to a remediation apparatus to generate a clean soil and mixing the contaminated soil with an aqueous cleaning solution to generate a soil solution. The method also includes subjecting the soil solution to vortical flow in a first direction and subjecting the soil solution to vortical flow in a second direction in an opposite lateral direction from the first direction. The clean soil can then be separated from a dirty aqueous solution. A remediation apparatus used to clean the contaminated soil that includes a chamber having a soil inlet for receiving a contaminated soil and a soil outlet. The chamber is angled downward from the soil inlet to the soil outlet to facilitate the flow of the soil solution through the chamber. The remediation apparatus also includes a first set of nozzles to inject an aqueous cleaning solution to create a first vortical flow zone in the chamber in a first direction and a second set of nozzles to inject the aqueous cleaning solution to create a second vortical flow zone in the chamber in the second direction.
