COLOR REMOVAL FROM TEXTILE EFFLUENTS BY ELECTROCHEMICAL DESTRUCTION

In this work, aqueous solutions of three azo dyes and a waste water sa mple taking from a local textile plant have been studied. Effect of se veral factors such as color, pH, presence of NaCl, applied potential, initial dye concentration and solution flow rate on the removal rate h as been investigated. Energy consumption values have been calculated f or different initial dye concentrations and flow rates, and shown as t he function of applied potential. Removal rates of 98%, 86% and 85% ha ve been achieved with energy consumption values of 0.044 k Whg(-1), 0. 106 k Whg(-1) and 0.044 k Whg(-1) for Ostazin Rod H3B, Ostazin Black H N and Ostazin Olive HG respectively. Removal rate of 82% with energy c onsumption value of 2 k Whm(-3) has been observed for textile effluent .
