Investigation of the decolorization efficiency of pin-to-plate corona discharge plasma system for industrial wastewater treatment
2015
In this paper a pin-to-plate high-voltage corona discharge system is designed to investigate experimentally the impact of pin and plate materials, thickness of ground plate and different salt concentration on intensifying the rate of Acid blue 25 dye removal efficiency from industrial wastewater. An investigation for the optimal air gap distance between pin and surface of wastewater is carried out using 3D-EM simulator to satisfy maximum electric field intensity at the tip of the pin. The results show that the optimum distance for corona discharge is approximately 0.5 cm. This distance is fixed through the study of the effect of materials, thickness, and salt concentration of wastewater.
