Removal of methylene blue from aqueous solutions using alum Sludge: Sorption optimization by response surface methodology

Abstract

A sorption process on low cost sorbents is one the promising methods for removing of these A sorption process on low cost sorbents is one the promising methods for removing of these pollutants from aqueous solutions. This report describes use of drinking water treatment pollutants from aqueous solutions. This report describes use of drinking water treatment sludge which is abundantly available from drinking water sludge which is abundantly available from drinking water treatment plants, to remove treatment plants, t methylene blue (MB) dye from aqueous solutions. The main objective of this work is to methylene blue (MB) dye from aqueous solutions. The main objective of this work is to determine the optimum conditions for removal of MB dye, a common compound that is used determine the optimum conditions for removal of MB dye, a common compound that is used as a model for organic chemicals. Response surface methodology (RSM) is us Response surface methodology (RSM) is used in the optimization of the sorption process. Six independent important factors which are temperature optimization of the sorption process. Six independent important factors which are temperature of treatment, pH of solution, dosage of sorbent, initial dye concentration, contact period of treatment, pH of solution, dosage of sorbent, initial dy and temperature of sorption were investigated using batch sor temperature of sorption were investigated using batch sorption technique with a 26 half factorial faced centered central composite design.
