This work presents the highest color removal efficiency for Textile wastewater by Electrocoagulation (EC) process using Aluminum as a sacrificial anode which is presently used for the purification of many types of water and wastewater. The effecting parameters such as applied electrical current, electrolysis time and initial pH were studied to achieve higher removals. In this process, sample was taken from real effluent of reactive dyes fabric. The performance of Electrocoagulation process was carried out in batch reactor at regular interval of 20 minutes. Obtained results indicated the most effective color removal efficiency was achieved at 0.75A of applied electrical Current. They were (97.5%-98.1%), at electrolysis time of 120 minutes, pH10, pH7 respectively and COD removal efficiency was (54 %-65%) at 0.75A, 0.9A respectively. In this work, the initial pH did not strongly affect the removal efficiencies significantly over a wide range. Therefore, adjustment of initial pH before treatment was not required in this practical application. The power consumption was found to be 6 kWh/m 3. To determine COD removal rate dependency to electrical current, a kinetic study was carried out and data were in good covenant with the first order kinetic model.

“…At its simplest, an electrocoagulation system consists of an anode and a cathode made of metal plates, both sub-merged in the aqueous solution being treated. The electrodes are usually made of aluminum, iron, or stainless steel (SS), because these metals are cheap, readily available, proven effective, and non-toxic [24].…”

This work has been carried out to minimize environmental pollution by investigation of efficient electrocoagulation of methylene blue by aluminum electrode cell setup using graphene oxide as adsorbent. The efficiency of dye removal was evaluated by the absorbance of methylene blue at 665 nm. The operating parameters for electrocoagulation such as current density (10-30 mA/cm 2), electrolysis time (5-20 minutes), pH of the medium (2 to 10), stirring speed (150-350 rpm), inter electrode distance (0.8 to 2 cm) and NaCl concentration (1.5-5.0 g/L) were optimized and found to be 30 mA/cm 2 , 20 min, pH 7.0, 300 rpm, 2 cm and 5 g/L respectively. The results showed that the dye removal efficiency was enhanced to 99% by the addition of graphene oxide. The result of the present research work can be useful for an efficient large-scale treatment of industrial effluents contaminated with methylene blue.

“…In all electrochemical processes, the electrical energy consumption is a significant parameter to the application of the Enhanced electrocoagulation-electroflotation for turbidity removal N. Djerroud et al process, mostly because it is related to the operating cost (Bayramoglu et al 2004;Ghanbari et al 2014).…”

The optimisation of the electrocoagulation‐electroflotation (EC‐EF) process assisted by the mucilage of the Opuntia ficus indica (OFI), on the turbidity removal was performed through the response surface methodology (RSM). For a solution of 300 mg/L of silica gel, high turbidity removal (93.14% ± 1.31) was obtained under the optimal conditions of 2.5 mg/L, 21.2 V, 9.65 and 2.61 mS/cm for the mucilage concentration, voltage, pH and conductivity, respectively, this experimental value was close to the predicted value of 92.96% ± 0.3. OFI mucilage increases turbidity removal efficiency and reduces specific energy consumption at a fixed current density. The turbidity removal of the EC‐EF process was improved by 30.94% compared with the conventional EC–EF (EC–EF without OFI mucilage) which shows 62.02% ± 1.45 of turbidity removal.
