Abstract

In this work, the effects of the variations of current density, initial conductivity of wastewater, initial wastewater pH and electrolysis time on aluminum electrode dissolution and energy consumption ofthe electrocoagulation treatment of a petroleum refinery wastewater have been studied.A central composite design was used to generate the set of experiments that were used for the investigations. The results of the experiments showed that the electrode dose was linearly affected by the electrolysis time and interactively by the current density and the pH. Dissolution being affected by the pH revealed that chemical dissolution contributed to aluminum electrode dose during the experiments. The energy consumption, on the other hand, was found to be affected by all the factors investigated except the pH. The results of the analysis of variancesthat were carried out on the responsesof the process showed that the models developed for the electrode dose and the energy consumption were statistically significant because their p-values of 0.0178 and <0.0001 respectivelyfound were discovered to be less than the significance level of 0.05.
