Abstract- Using a batch reactor configuration, this research examines how important physicochemical factors affect the efficiency of electro-oxidation of saltwater wastewater. For controlled tests, a rectangular Plexiglas reactor with a 1 L capacity was developed. It was powered by a DC source and had parallel graphite electrodes. To replicate circumstances of high COD and salinity, synthetic saline wastewater was created using hydrochloric acid and bovine serum albumin. The research examined the impact of four main elements on COD removal efficiency: pH, salt content, current intensity (voltage), and response time. A systematic approach was used in testing each component. Methods for water analysis are commonplace in the field, and statistical power analysis guided the design of the experiment. The findings showed that pH had a significant impact on COD removal (P < 0.001), with 11 pH being the optimal removal level. The highest rate of COD removal (~91%) was seen at a salinity of 30 g/L and a treatment period of 90 minutes. Both the response time and salt concentration had significant influences (P < 0.001 and P < 0.05, respectively). Similarly, voltage variation affected performance, with the best results obtained at 15 V. Optimizing physicochemical parameters is crucial for successful treatment of saltwater wastewater, as the research shows that electro-oxidation effectiveness is very condition dependent. Keywords:Wastewater, Salinity, Oxidation, Acidity, Conductivity.
