ELIMINATION DES COMPOSES ORGANIQUES PHENOLIQUES PAR COAGULATION-FLOCULATION AU SULFATE D’ALUMINIUM
Journal Title: Larhyss Journal - Year 2008, Vol 7, Issue 7
Abstract
The objective of the study is to observe the effectiveness of the coagulationflocculation by aluminium sulphate on the removal of organic compounds based on phenolic (phenol and catechol). Trials of Jar-Test has been made on phenolic compounds dissolved in distilled water and several reaction parameters were varied (pH, coagulant dose, organic content). The obtained results indicate that the process efficiency depends on the number and position of phenolic groups on molecules. The main mechanisms would be either a physical adsorption, an exchange of ligand or complexation on the floc surface of aluminum hydroxide.
