Textile is the largest industry of Bhilwara district in the state of Rajasthan. Bhilwara city is known as Textile City. The textile industries are most water and chemical intensive industry worldwide and produce large amount of waste water as colored dyes effluents. Colored effluents is toxic in nature and damage to the environment and ecosystem. For the production of 1 kg textile fabric industries consumed 200-400 litres of water. Textile effluent is contains inorganic as well as dissolved organic substances. Dark colour of waste water is due to the presence of residual dyestuffs. The photocatalytic decolorization of textile dye Methylene blue was examined by using photochemical reactor with WO3 and SnO2 photo catalyst in presence of U.V. light. The study of the effects of various environmental parameters such as type of catalyst, pH value and catalyst mass were also investigated by using spectrophotometer at different wavelengths.
