Abstract

Combined effects of electrolysis and ultrasound on the population of E. coli bacteria in aqueous solution of sodium sulfate were investigated. The kinetics of bacteria inactivation was determined employing these water purification techniques. It has been shown that the combination of ultrasonic and electrochemical treatments of aqueous solution significantly increases the rate of bacterial inactivation. It has been suggested that hydroxyl radicals formed as a result of the reaction occurred after treatment of aqueous solution by employing a combination of electrolysis and ultrasound are responsible for the death of bacteria. A correlation between the rate of hydroxyl radical formation and the inactivation rate of bacteria has been obtained.
