Non-thermal high oxidation methods, a novel high oxidation technique based on localized electrical discharges have been used successfully used to degrade high molecular weight organic compounds (dye solutions, kappa casein, humic acids,and fulvic acids) and also pharmaceutical compounds (carbameapazine).Organic contaminants are tested experimentally to determine the ability of pulsed corona power system in degrading these contaminants and leading to a safe drinking product. The role of electrostatic-sensitive nanoparticles (TiO2, activated carbon particles, and glass spheres) will be investigated in this research from both experimental and modeling aspects for the elimination of selected organic contaminants. The key focus of the research is on the impact of degradation efficiency of  the corona discharge reactor's different physical parameters, for example, frequency, pH, concentration, electrode shapes, and gap distances under a variety of conditions of the nanoparticles: concentrations, surface characteristics, sizes, etc. Modeling efforts will focus on the formulation and solution of predictive models for “global” reactor behaviors.
