Abstract
Water quality improvement and collecting safe water are two of the paramount concerns in today's world. Numerous water treatment and pollutant removal processes are introduced that vary with the type of pollutants. Among the proposed pollutant degradation methods, pulsed power is one of the effective methods that can be applied not only to degrade a wide range of contaminants but also to address the environmental issues associated with water treatment chemicals. The effectiveness of the pulsed power technology in water treatment was studied for a wide range of pollutants including microorganisms, nutrient pollution, emerging pollutants, and organic pollutants. This paper presents a review of pulsed power systems developed for organic and inorganic pollutants degradation in different water treatment applications. Also, it presents the effectiveness of several factors like the electrical characteristics of the pulse voltages and treatment time on degradation rates of different pollutants.

Summary
With respect to recent climate changes, efficient collection and storage of water are essential but not enough. N. Ghasemi et al.: Review of Pulsed Power Systems for Degrading Water Pollutants generation efficiency in the air, electrical discharges are usually used. For direct plasma method, pulsed arc and corona discharges are usually occurred in contaminated water/liquid resulting in free radicals and ion generation [30]–[32]. Water surface discharge (WSD), in the form of pulse corona or streamer discharge on the water surface, has been proposed for effective microorganism decontamination, degradation of hazardous organic compounds, and treatment of harmful algal blooms [13], [35] The advantage of this method is a simultaneous contact of the discharge plasma with gas and liquid molecules.
