Dye waste water pollutants are the major sources of environmental pollution. Textile waste water introduces intensive color and toxicity to aquatic system. Dyes possess complex aromatic structure. Hence conventional biological treatment methods are ineffective for decolourisation and degradation. Now a day’s Heterogeneous photocatalysis method is used for the treatment of textile waste water. Due to the high photo catalytic activity and stability of Zinc oxide, it is generally used as a photo catalyst for the removal of organic pollutants. Therefore the study has been made to determine the amount of decolourisation of the Napthal ASG dye using the catalysts ZnO with the combination of UV irradiation by Batch process. The influence of parameters such as catalyst loading, reuse of catalyst and initial concentration of the dye has been studied. In Batch process, the optimum dosage of catalyst for the concentration of 41600 mg/L was about 20g/L and the efficiency was about 83.90%.The dye was completely degraded in 30 min. After the first usage of catalyst it is dried in the sunlight and then it is used for the second time , its efficiency is 80.25% and 71.34% for the third time reuse of dosage.
