4. Conclusions
The peroxi electrocoagulation process was tested on the synthetic wastewater and the effect of operational parameters such as pH, amount of hydrogen peroxide, current density and electrolysis time on COD removal efficiency was investigated. The Azithromycin COD removal efficiency that was achieved using peroxi electrocoagulation process was 95.6% for the initial COD concentration 190 mg L−1. The ferric hydroxide and hydroxyl radical generated in the cell can be decreased the Azithromycin COD present in the wastewater. The optimal conditions for the process were determined to be [current density] = 20 mA cm−2, [hydrogen peroxide concentration] = 2 mM L−1, [electrolysis time] = 60 min, [mean energy consumption] = 2 kWh (kg COD)−1 and [pH]= 3.0. The results kinetic studies showed that pseudo second order equation model was found to be in good agreement with the experimental results. Finally, given the ultimate obtained results from this research, it became clear that, the process is technologically feasible.
