This study aimed to enhance the removal of non -steroidal anti-inflammatory drugs during coagulation-flocculation in the presence of aluminum sulfate alone and then in combination with powdered activated carbon. The Jar-Test was performed in the laboratory on aromatic organic compound (diclofenac) dissolved in distilled water. The purpose of the tests was to evaluate the removal efficiencies of diclofenac for variable doses of reagents and pH. The interactions of organic compound in the presence of the coagulant combined with the powdered activated carbon would be surface mechanisms (physical adsorption, ligand exchange or complexation on the surface of flocs of aluminum hydroxide or powdered activated carbon). Findings demonstrated that the addition of powdered activated carbon notably improved diclofenac removal, particularly under near-neutral pH conditions.
