The textile industry is one of the industries that causes bad water pollution due to direct discharge of wastewater into rivers. The World Bank estimated that from17 to 20 of industrial water pollution came from dyeing and fabric processing plants which cause alarming number for textile manufacturers as well as environmental managers and scientists. So far the methods of treating textile wastewater are used such as coagulation sintering biodegradation adsorption by activated carbon oxidation methods. Among these methods the biodegradation is widely applied to treat textile wastewater on a large scale. However under anaerobic condition azo dye can be reduced to byproducts as the very toxic aromatic amines. Recently we have found out advanced oxidation method which is a new and promising method for treating textile and dyeing wastewater. This method usually uses a catalyst as photocatalysts to generate OH radicals under
