Early studies have shown that electrocoagulation could be used for wastewater treatment (Picard, 2000). The iron electrode was used as the sacrificial anode; Thus, the first treatment plants using aluminum as the electrode appeared in later in the 1900’s to treat urban waste water. However, these experiments were stopped, a few years later (1930), because of the costs that were twice as high as that of conventional treatment. Studies conducted later ( Bollina 1947) revealed that for small sized facilities, electrocoagulation was much more advantageous than the conventional methods. Thereafter, research continued to develop and later in Russia they had discovered that electrocoagulation could be used for the treatment of surface water and in Norway they discovered electrocoagulation can be used to clean their drinking water that is rich in humic substances. (Vik 1984) (Picard 2000). Due to the current realization of the water pollution epidemic, governing bodies are becomiaction time and abatement by using more controlled parameters and smaller increments of flow.
