The decolorization of eight commercial azo dyes has been studied in a pilot scale photochemical reactor which employs W light and hydrogen peroxide to generate hydroxyl radicals for the destruction of organics in aqueous phase. Results of the decolorization of the simulated dye wastewater were measured by absorbance at characteristic wavelength. Target azo dyes were studied by other investigatiors, they showed no effect due to biomass through a traditional Activated Sludge Process. The results showed that the UV/H₂O₂ process is a very efficient treatment method on color removal. The effect of UV light intensity, hydrogen peroxide dosage, pH, and dye characteristics were also investigated.
