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. 

Introduction

According to reports on increasing nitrate concentration in the groundand surface-water, in recent years, there is some dilemma for nitrate pollution in drinking water.

PNF Co. offers selective electro dialysis process as an efficient solution for nitrate removal from drinking water.

Electro dialysis technology is an advanced method in water and wastewater treatment for solute contaminants removal. In this method, the water flows through the cationic and anionic membranes and the nitrate ions conducted to an ion concentrated section as a trap via an induced electric filed.
