In this work, we conducted a study that is to bleach wastewater loaded with ions, while using and optimizing the process of hybridized treatment of liquid effluents by of coagulation-flocculation/adsorption (CF-ADS). According to the separate optimization of flocculation processes (optimum dose of the flocculant (chitosan cross-linked by epichlorohydrin (chitosan-ECH))) and adsorption (activated carbon based on dates stones), we combined the two methods in order to increase performance fading exploited wastewater. The results of the rate of elimination separated by the methods of coagulation-flocculation, adsorption and are respectively of the order of 88.17% and 96.17% for the zinc and of the order of 83.68% and 95.4% for copper. While the results of the bleaching obtained by the hybrid method CF-ADS have shown that the bleaching rate was calculated as around 99.14% for zinc and of the order of 96.8%,for the copper, obviously very interesting with respect to the coagulation-flocculation(CF) and adsorption(ADS) used separately.
