Box-Benhken Experimental Design Optimization of the Coagulation Discoloration Process of Waste Water from Dyeing with Acid Dyes

Abstract:

The efficiency of Al2(SO4)3in discoloration of synthetic dyeing wastewater composed of two acid dye has been investigated. The influence of pH, coagulant concentration and initial dye concentration on the removal efficiency was analyzed in order to obtain optimum results. The optimization study through Box - Benhken experimental design was conducted in jar test to determine the interaction between the three factors and their effect on the discoloration degree. Very good effectiveness was found for the discoloration treatment of Acid Red 97 at optimal pH = 6.54, coagulant concentration 218 mg/L and an initial dye concentration of 181 mg/L, whilst for the second dye, Acid Yellow 42, the process lead to poorer results. Keywords: discoloration, coagulation, acid dyes, Box - Benhken experimental design
