A Comparative Study on the Competitiveness of Photo-Assisted Chemical Oxidation (PACO) with Electrocoagulation (EC) for the Effective Decolorization of Reactive Blue Dye

Accumulation of large quantity of non-biodegradable textile dyes into the environment made much attention to finding a suitable solution for the degradation of textile dyes. In this present study, decolorization efficiency of two different treatment technologies such as Photo-Assisted Chemical Oxidation (PACO – UV/H۲O۲) and Electrocoagulation (EC) on Reactive Blue ۱۹۴ dye solution (RB۱۹۴) at different operational conditions were analyzed and the competitiveness of the treatment technologies in terms of energy consumption and operational costs were discussed. Even though both the processes follow different mechanistic approach for the degradation of dye solution, both the processes achieved more than ۹۹% of decolorization efficiency. In terms of material/chemical consumption for the decolorization of dye solution PACO (US ۰.۰۱۶) competes with the EC (US ۰.۵۹۳۷). But in terms of electrical energy consumption as well as the overall operating cost EC process compete (US ۰.۰۴۸۱ & US ۰.۶۴۱۸) with the PACO process (US ۱.۰۲۶۷ & US ۱.۰۴۳۳۷).
