الملخص
The aim of this study is to appreciate the influence of several reaction parameters on the stoichiometry’smixture coagulant/ organic matter during the removal of organic matter by coagulation-flocculation withaluminium sulphate. Trials of Jar-test have been conducted on synthetic solutions of aromatic organiccompounds dissolving into distilled water then on mineralized waters. The organic compounds tested arehumic acid and pyromellitic acid which are showed carboxyl and/or hydroxyl functions with aromaticstructure. The trials of flocculation have for object to evaluate the removal efficiency of organiccompounds by varying several reaction parameters such as dose of coagulant, initial concentration oforganic compounds, pH and ionic strength of solutions. The determination of stoichiometry of reactionsbetween each organic compounds and aluminium sulphate has underlined that the stoichiometric lawsdepended not only of the compound’s structure but also on the pH and mineralization of waters. Thepredominant mechanisms in the process of removing organic acids tested could be phenomena ofcomplexation or ligand exchange with the soluble or insoluble aluminic species.
