Water Purification By Removing Chemical Materials From Water By Electrochemical Methods

Abstract

The current Study gives an Electrocoagulation Process for the Reduction of Nitrate Ions from Aqueous Solutions, to Meet the Standards of Water for Drinking Purposes.The effect variables such as pH Init, Current Density (i), Temperature (T), and Time (t) on the Reduction Efficiency was studied in Batch Reactor Using Aluminium Electrodes. The Optimal Reduction Conditions Were Proposed to be at pH = 7, Temperature of 30◦ C, Current Density 2.604 mA.cm-2 and Time of 120 min. The Results Showed that the Reduction Percentages for NO3- were 88.18% by Using Al Electrodes at 120 min. The Electrode Consumption was (0.167) kg/m3 and the Mean Energy Consumed was WSP= (3.5) kWh/m3.
