17/11/2013, · ,Iron, and aluminum are the common electrodes used for ,wastewater, treatment due to easy availability, low cost, and better dissolution. However, ,iron, is preferred because it is relatively cheaper. The aluminum plates are also finding applications in ,wastewater, treatment either alone or in combination ,with iron, plates due to the high coagulation efficiency of Al 3+ (Shen et al. 2003 ).

Electrocoagulation is a process consisting of creating metallic hydroxid flocs inside the wastewater by electrodissolution of soluble anodes made of aluminum or iron. The electrochemical oxidation of iron anodes produces ferrous, Fe2+ and ferric, Fe3+ ions. The Fe2+ ions can reduce Cr (VI) to Cr (III)
