In this study, we investigated the effect of ultrasound on diesel removal from soils. Lab-scale soil flushing experiments were conducted for various conditions involving ultrasonic power, particle size, and diesel concentration, using specially designed and fabricated equipment. The test results indicated that the rate of contaminant extraction increased significantly with increasing ultrasonic power. The degree of enhancement varies with test conditions. Physical imaging of the specimens during tests was realized using a microscope. The images showed the disintegration of soil grains and oil drops resulting in a variation in contaminant removal efficiency.
