- Abstract
- The present study evaluated the efficiency of combined biological and AOPs treatment (Bio-AOP) using Aeromonas hydrophila SK16 and AOPs-H2O2 (4%) for the remediation of the textile dyes. Bio-AOP treatment showed 100% decolorization of Reactive Red 180 (RR 180), Reactive Black 5 (RB 5) and Remazol Red (RR), while 72% decolorization was observed in individual treatments. Combined treatment significantly reduced BOD and COD of RR 180-78 and 68%, RB 5-52 and 83% and RR-42 and 47%, respectively as compare to individual treatment. Significant increased levels of tyrosinase, laccase, lignin peroxidase, riboflavin reductase and azoreductase were observed in A. hydrophila SK16. Fourier-transform infrared spectroscopy and high-performance liquid chromatography analysis showed noteworthy biotransformation of textile dyes. Possible metabolic pathway of degradation of dyes were predicted based on GC-MS analysis. This study indicates that the Bio-AOP treatment is more efficient than an individual treatment of textile wastewater.
