In iron electrocoagulation (Fe-EC), iron is dissolved nonstop using electricity, and the resulting ferric hydroxides, oxyhydoxides, and oxides form an absorbent readily attracted to arsenic. Current density, the amount of charge delivered per liter of water, of the process is often manipulated in order to achieve maximum arsenic depletion. This treatment strategy has primarily been used in Bangladesh, and has proven to be largely successful. In fact, using iron electrocoagulation to remove arsenic in water proved to be the most effective treatment option.
