“…The results proved that 97.5% of COD, 100% of colors were removed out of aqueous solution (Fig. 7b) at current density of 1 A dm -2 , pH of 5, electrolyte concentration of 6 g L -1 , an inter-electrode distance of 1 cm, the minimum power consumption of 0.55 kWh m -3 and reaction time of 45 min [39]. Moreover, Asaithambi et al, (2017) applied SEC for treatment of landfill leachate wastewater based on the evaluation of removal efficiency of color and COD along with consumption of power.…”

Due to the emergence of new and persistent pollutants in wastewater, various advanced oxidation processes (AOPs) such as ultrasonic technology and electrocoagulation have been developed and employed for pollutant degradation, removal, and recovery from wastewater. In this study, we investigated the principles, influencing factors, and practical applications of several methods combining ultrasound and electrocoagulation with catalysts and demonstrated the efficiency of each method. Additionally, we analyzed the challenges associated with these ultrasonic methods and electrocoagulation in removing antibiotics and recovering pollutants from aqueous solutions and suggested solutions to these problems. Materials recovered after treatment can be utilized to improve soil quality.

“…Electrical current decreased, voltage increased, and IR‐drop increased as the distance between the anode and cathode was increased. Furthermore, the reasons for the increase in power consumption and decrease in the percentage of COD removal of distillery effluent are reduced ion interaction with the hydroxide polymer and electrostatic attraction [68,69] . In order to get a higher percentage of COD elimination with minimum power usage from the AC‐EC/US process, therefore, 0.75 cm was found to be the ideal value for the inter–electrode distance between the cathode and anode.…”

Distillery industrial wastewater (DIW) was tested for color and COD removal percentages using an electrochemical and advanced oxidation processes (AOPs). Specifically, the study compared direct/alternating–current–electrocoagulation (DC‐EC/AC‐EC), sono (US), and direct/alternating current–electrocoagulation coupled with sono (US) (DC‐EC/US and AC‐EC/US) processes. Also evaluated were the effects of these procedures on the power needed to treat DIW. Experimental results showed that compared to single processes such as DC‐EC, AC‐EC, US, hybrid DC‐EC/US, and the hybrid AC‐EC/US process achieved a total color elimination efficiency of 100 % and a COD elimination efficiency of 100 % while using a lower power consumption of 4.76 kWhrm−3. The effects of important operational factors such treatment duration, cycle of pulse duty, sonication power, current density, chemical oxygen demand, electrode spacing, electrode pairing, pH, concentration of electrolyte on the % removal of COD and power usage of DIW were investigated using hybrid AC‐EC/US process. When using a Fe/Fe electrode combination, the effectiveness of COD removal was shown to be enhanced by increasing the treatment duration, current, US power, and decreasing the COD concentration, electrode spacing. The study also provided the results of an investigation into the synergistic index between AC‐EC and US process and operational cost. Based on its ability to efficiently and effectively remove contaminants from wastewater and industrial effluent, the AC‐EC/US approach stands out among the other methods.
