Removal of BOD, TDS, and phosphate from industrial parks wastewater by using a combined sono-pulsed electrocoagulation method

Abstract

Wastewater treatment is essential to the preservation of ecosystems and sustainable water management methodologies. It significantly affects both the preservation of water supplies and the reduction of water pollution. The processes of sono-pulsed electrocoagulation (S-PEC) were examined in this work to focuses on how much biological oxygen demand (BOD), phosphate (PO₃^-), and total dissolved solids (TDS) removed. The effects of initial pH, electrolysis time, and current as well as other experimental factors was determined for the highest percentage removal efficiency. The study found that the values of variables at optimal conditions were achieved the maximum removal efficiency used by the assisted S-PEC process. The optimal values for the highest removal percentages of the results for PO₃^-, TDS, and BOD were 99.70 %, 97.44 %, and 95.49 %, respectively, at pH = 7, electrolysis time = 40 min, and current intensity = 0.5 A. Overall, these findings show how much more effective the S-PEC is and how feasible it is to remove contaminants from industrial wastewater. The ultrasound waves and electrochemistry are used in the wastewater treatment process known as S-PEC to increase efficiency. For the most effective outcomes, it was essential to optimize variables including pH, duration, and current intensity, which lowers energy usage and operating expenses.
