Abstract

High sulphate concentrations in industrial effluents damage municipality infrastructures. Old corrugated iron was used as an electrode to remove SO₄^2-concentration in industrial effluents. Electrodes were characterized using SEM and EDS. The optimised parameters were pH 2, 3000 ppm, 15 V and 120 min. In an industrial effluent, 99% of SO₄^2- was removed including PO₄^2-, F^- and COD. The sulphates were physically adsorbed on Zn and Fe hydroxides according to first order kinetics. The corrugated iron is reusable and consumed low energy (0.1725 kWh/m³).
