Abstract

This work presents removal of COD (Chemical Oxygen Demand) from Pharmaceutical wastewater by Electrocoagulation (EC) process using Iron as a sacrificial electrode which is currently used for the purification of many types of water and wastewater. The effecting parameters such as applied voltage, electrolysis time and pH are studied to achieve higher removal. The performance of EC process is carried out in batch reactor. In this process, samples are taken out from the batch reactor at regular interval of 20 minutes. the experimental results also show that the COD removal is strongly influenced by the initial pH. The highest COD removal efficiency of 79.80% occurred at 1A, 16V at electrolysis time of 120 minutes with optimum pH 9 using Iron electrode. In this study, the EC process is proved effective and is capable in removing COD efficiently.
