Parametric and multiple response optimization for the electrochemical treatment of textile printing dye-bath effluent

► Electrochemical treatment of textile dye-bath effluent using aluminum electrode. ► Optimization of parameters like pH, current density, time and electrode distance. ► Multiresponse optimization by desirability function approach. ► Simultaneous COD and color removal maximization, and energy consumption minimization. ► Studies on disposal of residues generated.
