Inactivation of Escherichia coli by pulsed corona discharge in liquid environment

Although common techniques of water and wastewater treatment are well established, potential for new methods to improve the quality and effectiveness of water purification processing is still high. Among a number of methods that are under development, the pulsed corona discharge in water represents a promising alternative approach of chemical and biological decontamination of water. In this work the effects of corona discharge in water on bacteria Escherichia coli has been investigated. The contribution of UV radiation and hydrogen peroxide in the overall bacterial inactivation efficiency of the discharge was determined
