Abstract: The necessity for printed dye wastewater treatment was created by the fact that hundreds of industries produce mass quantities of those effluent from plastics and cardboard packaging processing. The characteristics of this wastewater create difficulties for choosing the treatment process, due to the fact of high concentrations of chemical oxygen demand (COD) and color that can’t allow to be processed by a classic biological method, so another method must be selected. The electrocoagulation (EC) process is a high effective method for the physicochemical profile of this wastewater. In this work used the electrocoagulation process to remove by precipitation colloid particles using aluminium (Al) electrodes. The basic principle is the application of current through a pair of metal electrodes (anode and cathode) to produce coagulants species which will interact with the colloid particles of the wastewater and lead to sedimentation. Furthermore, managed to develop a mathematical kinetic model for the COD abatement during this process and the kinetics of Al hydrolysis that take place in. Also, analyzed the mechanisms of the process and the parameters affected it and managed to calculate the kinetic parameters of the model. Finally, the simulation can be used as a tool to predict COD abatement with high efficiency results to similar profile wastewaters for further investigation.
