“…The increasing of voltage increased the coagulation rate by production of air bubbles and reduced their size on the liquid surface at reactor. The efficiency of turbidity reduction was increased at higher electrolysis times under certain conditions, which has been attributed to the greater solubility of anode (Kobya et al 2003;Terrazas et al 2010).…”

“…The process contains bath residues from pulp preparation, deinking separation and flotation, pulp cleaning and washing, dispersing, bleaching, and other important operations. These residues may cause severe pollution including dye, color, biological oxygen demand (BOD), and chemical oxygen demand (COD) if they are not properly treated before discharge into the receiving environments (Young and Akhtar 1998;Ali and Sreekrishnan 2001;Aksu and Gonen 2004;Ugurlu et al 2008;Emamjomeh and Muttucumaru 2009;Terrazas et al 2010).…”

“…It is difficult to treat and purify this wastewater and to estimate the hazards (Ali and Sreekrishnan 2001;Ragunathan and Swaminathan 2004). The treatment systems apply physical, chemical, biological, ozonation, or a combination of methods for effective purification of industrial paper wastewater due to the variation of wastewater characteristics (Basak and Gokay 1999;Fu and Viraraghavan 2001;Tezel et al 2001;Santos et al 2002;Ragunathan and Swaminathan 2004;Terrazas et al 2010;Tezcan UN et al 2016;Hubbe et al 2016).…”

The goal of this work was to evaluate the efficiency of electrocoagulation technique in deinked tissue industry wastewater. The effect of two types of electrodes, three electrolysis times, four voltages, and three pHs were investigated. Experiments were conducted in batch process using a glass cell. The chemical oxygen demand (COD) removal and turbidity improvement of wastewater were measured and evaluated through the independent and interaction effects of variables. The results revealed that both electrodes reduced the COD and turbidity. However, the ability of their performance depended on the electrolysis time, voltage, and pH. For COD, greater improvement by electrocoagulation technique was obtained with an electrolysis time of 45 minutes, 24 volts, and alkaline conditions, while the turbidity reduction was achieved at lower voltage. Analysis of the treated water showed that the maximum COD and turbidity removal efficiencies were 81.12% and 89.43%, respectively. The treated effluent was very clear, and its quality met the industrial applications. Consequently, the electrocoagulation technique can be considered a reliable and safe method for deinked tissue effluent treatments to replace the other chemical methods.

“…Several authors reported the electro-coagulation method could be more suitable for high polluted wastewater [15,22,38,39]. Zaied and Bellakhal [40] concluded that electro-coagulation is an effective, fast and economic technique for treatment of black liquor resulting from paper industry [40].…”
