A synthetic ,dye, in ,wastewater, cannot be efficiently decolorized by traditional methods. This is because of the high cost and disposal problems for treating ,dye wastewater, at large scale in the textile and paper industries [16]. The technologies for colour removal can be divided into three categories: biological, chemical and physical [15].

In this research, sludge of Jalaliyeh ,water treatment plant, in Tehran was used as an alternative coagulant for the removal of a specific type of ,acid dye, (,acid, red 119 (AR119)). For this purpose, the effect of initial pH, coagulant dose and initial ,dye, concentration on ,dye, removal efficiency were investigated. Results showed that the ,dye, removal rates were largely dependent on pH.
