Abstract :The efficiency of polyaluminium chloride insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(compared to the conventional coagulants such as Al2insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
