OPTIMIZATION OF SOIL MIXING TECHNOLOGY THROUGH

Enhanced soil mixing is aprocess used to remove volatile organic compounds (VOCS)from soil. In this process, also known as soil mixing with thermally enhanced soil vapor extraction, or SM7TESVE, a soil mixing apparatus breaks up and mixes a column of soil up to 9 m (30 fi) deep; simultaneously, hot air is blown through the soil.
