Abstract

A series of experiments with a laboratory scale ultrasound treatment system for MTBE polluted groundwater was performed to increase the efficiency of MTBE degradation in groundwater. This study evaluated several factors to increase the efficiency of MTBE treatment for artificial and natural groundwater. The treated volume of groundwater, ultrasound frequency and power, and pollutant concentrations have been changed to evaluate its effects on the degradation efficiency of MTBE in batch and continuous flow reactor. For the specific experimental conditions on this paper, MTBE degradations are more efficient at 580 kHz than those at 1 MHz. The efficiency of MTBE degradation is proportional to the intensity of ultrasound power per unit volume of MTBE polluted groundwater. The concentration of ions in groundwater does not much affect the efficiency of MTBE degradation. The $1^{st}$ order degradation constant of MTBE for different power per unit volume at 580 kHz shows linear relationship at same concentration. The $1^{st}$ order degradation constant for 0.1 mM MTBE solution is higher than that for 1 mM MTBE solution. These experimental results could be helpful to seek optimal conditions for relatively large volume of polluted groundwater treatment.
