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
