“…In order to maximize COD and the other water quality parameters removal, Box-Behnken design (BBD) and response surface methodology (RSM) were used to design the experiments and optimize the operating conditions [26]. In fact, the electro-Fenton process can be applied when there are large amounts of COD in wastewater and BOD5/COD ratio is less than one [24]. Furthermore, a car wash wastewater is containing huge amounts of sands and suspended solids which assist the electro-Fenton process that is based on the flocculation and coagulation.…”

“…Cost-effectiveness and simplicity of operation are the other advantages to make EF suitable for wastewater treatment [22,23]. The EF process which is a combination of Fenton and electro-coagulation processes has a high impact in treating hazardous and organic pollutants [24]. In this process with in situ production of hydroxyl radical as the second most powerful oxidizing species (E˚=2.8V) is able to oxidize organic pollutants to inorganic ones (Eqs.…”

In this paper, a car wash wastewater (CW) was treated by an economic and eco-friendly method called electro-Fenton (EF) technique. The experiments were conducted to investigate the effect of five important variables including reaction time, current density, pH, H2O2/Fe2+ molar ratio and H2O2/Car wash wastewater (mL/L) on the quality characteristics of wastewater such as COD, BOD5, TOC, TSS, heavy metals, EC, surfactants and hardness. By applying Box-Behnken design (BBD) and response surface methodology (RSM), the optimum operating conditions were obtained. The optimum conditions for COD [as a main factor in a wastewater (according to the environmental protocols)] removal of 68.72% were experimentally found at reaction time of 75.80 min, current density of 58.81 mA/cm2, pH of 3.02, volume ratio of H2O2/CW of 1.62 mL/L, H2O2/Fe2+ molar ratio of 3.66.
