Electrocoagulation (EC) is an effective process in the treatment of oily wastewater, however, only a few studies have explored the parameters affecting the efficient design of the reactors employed in this process. In this study, a statistical investigation on the factors affecting the design of a continuous electrocoagulation reactor was performed by running the tests designed based on the design of experiments (DOE) principles. The explored design variables were current density (30-80 A/m2), reactor residence time (10-30 min), and the ratio of anode surface to the reactor volume (15-45 m2/m3), which were optimized by the response surface method (RSM) to maximize the amount of oil removal...
