Colored Wastewater Treatment Apparatus using Nanostructured Electrodes

Introduction

This device is a colored wastewater treatment apparatus using nanostructured graphite electrodes which operates based on electrolysis process. These electrodes are produced by cold plasma method. Carbon compounds, especially graphite, have great properties which make them interesting for utilization as a cathode electrode. Using different types of modification methods in different systems make colored compounds, p-nitrophenol contaminants, azo dyes elimination and hydrogen peroxide production possible. Among electrode modification methods, plasma- based methods are generally cheap, clean and easy, which require less time. In order to purify the wastewater, firstly the carbon electrodes are modified by the plasma process to increase specific surface area and H2O2 production on the surface of the electrodes and then, modified electrodes are used as a cathode for electrolysis of wastewater.
