This research investigates the effect of electrooxidation (EO) process on treatment efficiency, discharge criteria, and water reuse or irrigation standards industrial slaughterhouse wastewater (ISWW). The study was carried out different anode materials such as (Ti/Pt-IrO2, Ti/RuO2-IrO2, Ti/RuO2, Ti/IrO2-Ta2O5), current densities (50-150 A/m2), reaction time (0-540 min). COD, TOC, turbidity removal efficiency under optimum conditions (anode = Ti/Pt-IrO2, j 150 A/m2, t 360 min) were calculated 99.6, 96.1, 99.9%, respectively. energy consumption total operating cost 68.3 kWh/m3 (15.4 50.6 kWh/kg COD TOC) 2.40 $/m3 (0.62 2.02 $/kg TOC), Furthermore, results are compared together with existing published/reported criteria for adequate environmental release in jurisdictions worldwide. Additionally, a relationship has been established between World Bank Group/United States Environmental Protection Agency (WBG/US EPA) standards. At end study, biodegradability ISWW after EO assessed using carbon oxidation state (COS) average (AOS) parameters, kinetic modeling heterogeneous kinetics comprehensively evaluated. findings show that Ti/Pt-IrO2 is an efficient method treatment.
