The main proposed objective was reducing the concentration of pollutants from the model systems with dye concentration 200 mg/l,dispersant concentration 60 mg/l, and ethylene glycol dispersant 60 mg/l respectively, to admissible norms for discharge into water basins. According to the research results, it was found that the most efficient method for simple and complex model systems, is coagulation [Al 2 (SO4) 3] = 0.1M followed by adsorption on activated carbon, behind which were obtained values of COD -CR about 95% and the effect of fading can reach up to 100%.roape reziduale textileprocese de epurareArticle
