Treatment of Polluted Hindon River Water by Electrochemical Technique

River Hindon is one of the most polluted rivers in western Uttar Pradesh, India. Treatment of Hindon river water is a challenging task due to large variety of inorganic, organic chemicals and microorganisms. The objective of present work is to study the application of electrochemical technique in the treatment of polluted Hindon river water. Experiments were carried out in an electrochemical cell by sacrificial electrodes, iron as anode and aluminium as cathode in a batch process. Effect of operating variables, viz., current density and electrolysis period was studied for reduction of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Dissolved Oxygen (DO), Total Hardness (TH), Total Alkalinity (TA) and Microbial Population (MP) at room temperature (25 0 C). Other parameters like pH and power consumption were also investigated. The applied current density and electrolysis period were found to effect significantly in reducing all parameters. The benefits of this process were observed in reducing capital and operating costs compared to other conventional treatment processes.
