DESCRIPTION OF SOIL RECLAMATION AND REMEDIATION .

Problems of process control, especially in the case of in-situ techniques. Ex situ techniques Soil washing This ex-situ method is mostly used for removing inorganic contamination, such as heavy metals, radio-nuclides, toxic anions and others. In some cases, it can be applied to organic contamination.

ART Engineering LLC - Soil Washing Plant Systems

Soil Washing. In the washing process, the fine clay and silt particles are separated from the coarser sand and gravel soil particles. The separated fines and contaminants are dewatered into a dry filter cake suitable for off-site disposal. Additional treatment of the sand and gravel fractions maybe incorporated into the process as needed.

Based on these results, 35 kHz was selected for the ultrasonic soil-washing processes in this study. The optimal washing time was found to be 1 min, because there was no significant increase in the removal efficiency over 1 min for the three processes, mechanical, ultrasonic, and combined ultrasonic−mechanical.

The Soil Washing Process Soil washing is a process whereby contaminants adhere to the fine-fraction of the soil, such as organic matter and clay/silt. The principle of the method utilizes the difference in grain sizes and density of the materials and separates the different fractions by means of screens, hydro-cyclones and upstream classification.
