Abstract: In the world, different types of industrial activities are fastly growing day to day and it produced various kinds of wastes and wastewater. Among these fast growing industries most dangerous and needful industry is textile industry. But its effluents are damaged the environment and ecosystem. So its treatment is very essential for maintain the good environment and healthy atmosphere to all creatures in to the earth. The present study mainly focussed on the treatment of synthetic textile wastewater by fluidized bed Fenton process and investigated the efficiency of this Advanced Oxidation process for removing COD and colour. Synthetic textile wastewater prepared by Reactive ultra-red dye. In this study used various parameters such as pH of solution,Fe2+ concentration and H2O2 concentration. The fluidization conducted with different carriers like Silicon dioxide and Aluminium Oxide .The comparative study of COD and Dye removal efficiency by two carriers also carried out in this experiment. The study proved that both carriers are effective for achieved the target .But the Al2O3 experimental result shows that maximum COD removal efficiency of 79% obtained at pH-3, Fe2+ -3mg/l and H2O2- 200mg/l and maximum Dye removal efficiency of 90.1% attained at pH-3, Fe2+ -4 mg/l and H2O2- 200mg/l.The SiO2 experimental results shows that maximum COD removal efficiency of 89% obtained at pH-3, Fe2+ -3mg/l and H2O2- 200mg/l and maximum Dye removal efficiency of 96.8% attained at pH-3, Fe2+ - 3mg/l and H2O2- 200mg/l. So the present study proved that carrier silicon dioxide is very effective for removing colour and COD from textile wastewater by Fluidized Bed Fenton process .
