Özet

Purpose: The purpose of this paper is to investigate the electrochemical treatment of textile dye wastewater in the presence of NaCl electrolyte by using aluminium electrodes. Design/methodology/approach: The electrochemical treatment of textile dye wastewater was optimized using response surface methodology (RSM). RSM-based D-optimal design was employed to construct statistical models relating turbidity and designed effective parameters known as current density, electrolyte concentration and electrolysis time. The experimental plan consists of a three-factor (three numerical) matrix. Findings: The results show that the current density has significant effect on the reduction of turbidity. Besides, electrolysis time is the most influential factor on the turbidity. In order to enhance the electrochemical treatment performance, no coagulant addition or further physicochemical processes were employed. Originality/value: Industrial certain textile dye wastewater in Turkey is used to determine optimal values. © Emerald Group Publishing Limited.
