A novel soil washing equipment for fine grained soil was developed. The system comprises slurry transfer and mixing process applying impact force with soil/liquid separation process. Highly pressurized water was injected to apply physical impact on the slurry. A field soil contaminated by heavy metals (Pb, Cu and As) from an old refinery site was investigated to evaluate the contaminant removal effectiveness of the equipment. Three kinds of soil washing methods including physical desorption, chemical solubilization, and the combined effort were performed in this study. The best removal effectiveness was found in the combination of physical and chemical treatments; 89% of Pb, 87% of Cu, and 84% of As. The test results show contaminant removal effectiveness in soil washing system can be enhanced using proper physical impact system.
