| Description |
In this study, hydroquinone was removed from water by electrocoagulation using flow electrolyzer in mono polar and bipolar
configurations in a batch recirculation mode of operation. Treatment performances of such effluents have been evaluated in terms of
chemical oxygen demand removal. The effect of important operating parameters such as current density, flow rate, concentration of
hydroquinone and supporting electrolyte on the pollutant removal and energy consumption is critically evaluated. The experimental
data were analyzed using response surface methodology (RSM).MaximumCOD removal inmonopolar configuration of 80.95% was
noticed at condition of supporting electrolyte concentration 2.67 g L−1, flow rate 27 mL min−1, current density 0.7 A dm−2 at energy
consumption of 2.36 kWh per kg of COD for the 1000 mg L−1 of hydroquinone concentration. In the case of bipolar configuration
a maximum COD removal of 87.13 was noticed at: supporting electrolyte concentration 4 g L−1, flow rate 29.15 mL min−1, current
density 1 Adm−2 at energy consumption of 8.495 kWh per kg of COD for the same hydroquinone concentration.
