Treatment of Contaminated River Water by Batch Electrocoagulation System Using Aluminium and Iron Electrodes: Performance of Process and Statistical Analysis

This study examines the reduction efficiency of chemical pollution of freshwater by electrocoagulation (EC) process using aluminium (Al) and iron (Fe) electrodes. Several parameters affecting the EC efficiency were investigated in batch manner. Results indicate that both Al and Fe electrodes can eliminate satisfactorily the chemical pollutants of water. The Fe/Fe pair electrode showed an excellent efficiency in reducing turbidity (≈ 99
