Paint discharges contain polluting agents that are highly harmful to the environment. The work proposed makes it possible to apply electrocoagulation as a process for treating paint-based effluents. Two types of paints (water and oil paints) are considered in this study. The electrocoagulation reactor used is equipped with two flat aluminum electrodes. The electrocoagulation process in an acid medium gives a better electrolysis yield allowing a sufficient quantity of ionic coagulant (Al3+) to be obtained. The ionic coagulant will, among other things, considerably reduce the turbidity parameters of the pollution. The depollution process used for the various paints considered in this study makes it possible to conclude that the method is promising on an industrial scale due to the fact that the mud obtained does not have a complex composition either to recycle their rejection or the starting products in nature.
