In the present study, Fenton's oxidation of a chromium complex disazo ,dye, (,Acid, Blue 193) synthesis ,wastewater, was evaluated, modeled and optimized by employing Central Composite Design. Within this context, the individual and interactive effects of critical process parameters such as Fe2+, H2O2 concentrations, initial chemical oxygen demand (COD) and reaction time was assessed.

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.

Chitosan is the only natural cationic polymer, which can be used as an excellent non-toxic biosorbent for almost all anionic dyes including ,acid dye,, reactive ,dye, and direct ,dye, (Zhao et al. 2012). However, raw chitosan presents some major difficulties of unsatisfactory mechanical properties and dissolution in acidic media in the adsorption process ( Kyzas & Lazaridis 2009 ).
