Abstract

The objective of the present study is to be adapt pulse power technique for water treatment where an attempt has been made for recycling of the Reactive Oxygen Species (ROS) present in gaseous phase to aqueous phase and further to improve the pollutant degradation. Methylene blue (MB) was used as a model pollutant and its degradation was compared by recycling and non-recycling of ROS in the reactor. The study showed better degradation of pollutants (MB) while recycling the ROS as compared to the non-recycling condition. To support the results the different ROS such as hydrogen peroxide, Ozone and hydroxyl radicals were quantified in both conditions. We observed that the concentration of ROS present in the aqueous solution was higher in recycling conditions as compared to that of non recycled condition.
