SOIL WASHING TREATMENT

Soil washing can be used either as a stand-alone technology or in combination with other treatment technologies. In some cases, the process can deliver the performance needed to reduce contaminant concentrations to acceptable levels and, thus, serve as a stand-alone technology. In other cases, soil washing is most successful when combined with

SOIL WASHING TREATMENT | Science Inventory | US EPA

Soil washing is a water-based process for mechanically scrubbing soils ex-situ to remove undesirable contaminants. he process removes contaminants from soils in one of two ways: by dissolving or suspending them in the wash solution (which is later treated by conventional wastewater treatment methods) or by concentrating them into a smaller volume of soil

Soil Washing | Geoengineer

Jan 29, 2013· Further treatment of the soil through other more expensive treatment methods would then be necessary and the use of soil washing under these circumstances might not save any time or money. In general, soil washing is ineffective for soils containing more than 30 to 50% silt, clay or organic matter (Sharma and Reddy 2004, US EPA 1993).
