Abstract
An apparatus for treating contaminated soil is disclosed. The apparatus includes a reactor vessel for holding a volume of water which is subdivided into a first chamber and a second chamber. The chambers are in fluid communication and are partially separated by a baffle. A soil conveyor is provided for conveying a supply of the contaminated soil to the first chamber. A gas supply directs a supply of pressurized gas into the first chamber, thereby creating a turbulent mixture of soil and water in the first chamber to effect segregation of the soil into a substantially small particle size first fraction and a substantially large particle size second fraction. The reactor vessel includes a first outlet located in a lower portion of the second chamber for withdrawing a slurry comprising the second soil fraction from the reactor vessel. The lower portion of the second chamber may be funnel-shaped to help direct the mixture of soil and water toward the first outlet.
