“…This mechanism was also responsible for turbidity removal in EC operation. The second mechanism is indirect oxidation in the EO reactor at acidic pH values 58 , 59 . EC-EO process performance tended to reduce at alkaline initial pH values due to the formation of , decrease in active sites on the surface of Al(OH) 3 (H 2 O) 3 flocs and poor oxidative properties.…”

A synergistic combination of electrocoagulation-electrooxidation (EC-EO) process was used in the current study to treat domestic greywater. The EC process consisted of an aluminium (Al) anode and an iron (Fe) cathode, and the EO process consisted of titanium with platinum coating mesh (Ti/Pt) as an anode and stainless steel as a cathode. The effect of operative variables, namely current density, pH, EC time and EO time, on the removal of chemical oxygen demand (COD), colour, turbidity, and total organic carbon (TOC) was studied and optimised using Response Surface Methodology (RSM). The results showed that although the pH affected the removal of all studied pollutants, it had more effect on turbidity removal with a contribution of 88.44%, while the current density had the main dominant effect on colour removal with a contribution of 73.59%. It was also found that at optimal operation conditions for a current density of 2.6 A, an initial pH of 4.67, an EC time of 31.67 min, and an EO time of 93.28 min led to a COD, colour, turbidity, and TOC removal rates of 96.1%, 97.5%, 90.9%, and 98%, respectively, which were close to the predicted results. The average operating cost and energy consumption for the removal of COD, colour, turbidity, and TOC were 0.014 $/m3 and 0.01 kWh/kg, 0.083 $/m3 and 0.008 kWh/kg, 0.075 $/m3 and 0.062 kWh/kg, and 0.105 $/m3 and 0.079 kWh/kg, respectively.

“…This method is often known as "green technology" since it requires little or no chemicals for water treatment [3,77]. The EOP process is predicated on the direct (electrooxidation or electro-reduction on the electrode surface) or indirect (through chemical oxidants generated in treated water) oxidation of organic substances using graphite, stainless steel, dimensionally stable electrodes (Ti/PtO2-IrO2, Ti/RuO2-TiO2, Ti/RuO2-IrO2, Ti/IrO₂/RuO₂ ,and Ti/IrO2-Ta2O5) and an insoluble anode material such as platinum and boron coated diamond [8,28,29,44].…”

In this study, the treatment performance of the process in the removal of Endocrine Disrupting Compounds (EDCs) from domestic wastewater by a laboratory-scale electrooxidation process using Ti/IrO₂/RuO₂ electrodes as an anode was evaluated using response surface method (RSM). The effect of pH, current density, and flow rate on the electrochemical treatment of 17α-ethinylestradiol, β-estradiol, triclosan, and estrone, which are often present in wastewater, has been studied. Using Box-Behnken Design (BBD), the parameters influencing the removal efficiencies were optimized for the Electrooxidation process (EOP), and the models created essential second-order quadratic models for the EOP process. The Response Surface Method yielded results that reasonably agreed with the measured values. The maximum removals of triclosan, 17α-ethinylestradiol, and β-estradiol were attained at 92,90%, 97,76%, and 95,36% respectively, under experimental conditions optimized pH= 3,68, current density= 20 A and flow rate= 8,83 mL/min for EOP. Removal efficiencies have achieved their maximum levels at low pH, high current density, and low flow rate. At the same time, the electrooxidation method could not completely remove the estrone.
