Effect of the continuous and pulse in situ iron addition onto the performance of an integrated electrochemical-ozone reactor for wastewater treatment

► Novel technology based on electrochemical-ozonation processes operated by pulses. ► We describe energy input effects (continuous and by pulses) on removing COD, color and turbidity from industrial effluents. ► Energy requirements are diminished up to half when this is pulsed without sacrificing pollutant removal efficiency. ► Sludge generation and electrodes passivation is also decreasing by pulsing operation.
