COMPORTEMENT DE SUBSTANCES HUMIQUES DE L’EAU DU BARRAGE ZIT EL AMBA AU COURS DE LA COAGULATION-FLOCULATION EN PRESENCE DE SULFATE D’ALUMINIUM ET DE CHARBON ACTIF
Journal Title: Larhyss Journal - Year 2016, Vol 26, Issue 26
Abstract
The aim of this work is to optimize the elimination of humic matter in dam water Zit El Amba by coagulation-flocculation. The reagents used are the only aluminium sulphate and then coupled with an adsorbent material, powdered activated carbon. After studying the physicochemical quality of collected raw water samples, jar test trials were conducted by monitoring organic parameters, turbidity, pH and TAC. The removal efficiencies of humic substances were not very significant when the aluminium sulphate was used alone. When the coagulant was combined with powdered activated carbon, removal was significantly improved. The removal mechanisms of aquatic humic material can be complex because they may be subject to numerous interactions with inorganic or organic substances in dissolved and colloidal form.
