Description
Summary:	The efficiency of polyaluminium chloride (PAC) in discoloration of synthetic dyeing wastewater composed of reactive or direct dye has been investigated, taking into account the proven advantages of PAC in water purification processes (compared to the conventional coagulants such as Al2(SO4)3, FeSO4, etc.). The efficiency of PAC was determined by UV/VIS spectroscopy, controlling the UV/VIS absorbance changes of the wastewater samples after their treatment with the appropriate amount of PAC. Coagulant concentration and pH influence on the removal efficiency was followed in order to derive the optimum results. Excellent efficiency of PAC (100%) was found for the treatment of direct dye, Cuprophenil Blau 3 GL, at optimal pH=7.1 and concentration of 15 mg/L Al. The optimal results for reactive dye Bezaktiv Türkisblau V-G, enabling almost 80% dye removal, were obtained at pH=7.1 and PAC concentration of 20 mg/L Al.
