Abstract Wastewater from textile processing plant can be highly colored and difficult to decolorize. Combined UV and hydrogen peroxide oxidation has been applied successfully to the treatment of various water pollutants. In the present study, advanced oxidation treatment, UV/H202 was applied to decolorization of three azo dyes, Acid Orange 7, Acid Orange 8 and Methyl Orange. The study described herein is an investigation of treatability of these dyes in the continuous circulation photoreactor. The UV radiation was carried out with a 15 W lowpressure mercury lamp. Rate of color removal have been studied by measure of the absorbency at characteristic wavelength. We have observed that the decolorization rea
