The Fenton AOP has been used for organic pollutant degradation for the last many decades; due to the requirement of high concentrations of Fenton reagents (Fe 2+, H 2 O 2, H 2 SO 4; pH: 2.5 to 4) and high temperatures (323 to 353 K), the process lost reality for real industrial dyeing effluent treatment. The objectives of the study were to enhance the dye degradation reaction rate from dyeing effluents, minimize the concentrations of Fenton reagents, and lower the process temperature, thus making the process suitable for industrial dyeing effluent treatment. The result of the research exposed a significant improvement of the azo dye degradation rate from a mixed azo dye effluent by the catalytic role of micelles through Fenton AOP. The result of the azo dye degradation rate from MDE was found to be 62.43% in aqueous
