The Use of Cold Plasma for Water Treatment-a Review

Cold plasma for water treatment has been studied and successfully applied to water treatment in the world, and has attracted scientists in Vietnam in recent years. Cold plasma is normally generated with electric discharges in high voltage. Dielectric barrier discharges and pulsed corona discharges are the most feasible methods. Cold plasma technology has shown to efficiently destroy bacteria, decompose organic compound and deal with heavy metals. This paper reviews the methods of generating cold plasma, interaction between cold plasma and water, research achievements as well as unexpected impacts. In addition, this paper also introduces an experimental model being studied and developed in the near future
