The aim of this study was to investigate the impact of sonication as a disinfection method for determining the effectiveness of ultrasound waves on the inactivation of E. coli. Ultrasound waves at a frequency of 42 kHz were used to expose aqueous suspension of E. coli. Ultrasound waves display a strong influence on the rate of E. coli disruption in water. Inactivation occurs most at the highest sonication time. This study show that sonication in 42 kHz is capable to some degree of inactivating E. coli.
