“…In the same year, a research group also conducted a study using the EC process for the reduction of color and turbidity of textile industry effluents. The studies were conducted with effluents with the initial COD, turbidity, and color index values of 5855 mgo 2 ·L –1 , 100.0 NTU, and 398.0 mgPt-Co·L –1 , respectively.…”

Electrocoagulation (EC) is an efficient treatment method that involves the electrodissolution of anodes, the formation of coagulants in situ, and the production of hydrogen at the cathode, facilitating the removal of pollutants by flotation. Industry in general aims to reduce the contaminant load, expressed as chemical oxygen demand (COD), and EC effluent treatment is particularly effective in this process. The development of EC processes has been an efficient alternative for the treatment of effluents with high pollutant loads, such as tannery, pulp and paper, textile, beverage, and food industries, and many demonstrate the potential for application in car wash effluent. This study presents a review of the use of EC for the treatment of various effluents containing COD, OGs, surfactants, color, and turbidity, but with a greater focus on the vehicle washing sector. It also discusses the factors that influence the efficiency of EC and the main discussions of the authors. Presently, the investigations of studies already carried out show that the performance of the EC process is dependent on many relationships and factors, such as the type of material constituting the electrode, the electric potential difference, the electric current density, the distance between electrodes, the surface area of the electrodes, the pH, the initial concentration of contaminants, the conductivity and the treatment time. The review demonstrated that the EC process has been employed in the treatment of many types of effluents and with relatively high efficiency rates, in general, between 60.0% and up to 90.0%, aiming at the reduction of the COD indexes, the reduction from 60.0% up to 99.0% of color content, the 87.0% reduction of chromium. In turn, for turbidity, it varied on average from 44.0 to 99.0%. For other parameters such as MBAS and OGs, in most studies, the reduction exceeded 90.0%.

Solid‐waste management, particularly of aluminum (Al), is a challenge that is being confronted around the world. Therefore, it is valuable to explore methods that can minimize the exploitation of natural assets, such as recycling. In this study, using hazardous Al waste as the main electrodes in the electrocoagulation (EC) process for dye removal from wastewater was discussed. The EC process is considered to be one of the most efficient, promising, and cost‐effective ways of handling various toxic effluents. The effect of current density (10, 20, and 30 mA/cm2), electrolyte concentration (1 and 2 g/L), and initial concentration of Brilliant Blue dye (15 and 30 mg/L) on the efficiency of the EC process were examined in this study. The results show that removal efficiency increased with current density and sodium chloride (NaCl) concentration and decreased with initial dye concentration. The electrical power and electrodes consumed increased with an increase in current density and decreased notably with increased NaCl. The optimum current density and amount of NaCl were 20 mA/cm2 and 2 g/L, respectively to attain highest values of E133 brilliant blue dye removal. The EC process was examined using adsorption isotherms and kinetics models. Those results showed that the Langmuir isotherm matched the experimental data. Furthermore, the experimental data were followed the Elovich model kinetics.
