Optimization of parameters for dye removal by electro- -oxidation using Taguchi Design

Abstract

The aim of the present investigation is to treat the dye house effluent using electro-oxidation and to analyse the result using Taguchi method. L16 orthogonal array was applied as an experimental design to analyse the results and to determine optimum conditions for acid fast red dye removal from aqueous solution. Various operating parameters were selected to study the electro-oxidation for the colour removal of the effluent. The operating parameter such as dye concentration, reaction time, solution pH and current density were studied and the significance of the variables was analysed using Taguchi method. Taguchi method is suitable for the experimental design and for the optimization of process variables for the dye removal.
