A simulated wastewater containing C.I. Acid Orange 52 was treated by ozone in a polyvinylidene fluoride (PVDF) hollow Fiber membrane reactor, Ozone-containing oxygen was passed through the tube side of the module continuously, while the aqueous feed was passed through the shell side of the membrane reactor in recirculation mode. The effect of pH, liquid flow rate, gas flow rate, and initial dye concentration on the decolorization was investigated. The results showed that decolorization efficiency increased with the increase of liquid and gas flow rates, but decreased with increasing initial dye concentration. When pH varied from 5.6 to 8.6, it had little effect on the decolorization efficiency, indicating the decolorization of C.I. Acid Orange 52 by ozonation in the membrane reactor is mainly a direct reaction rather than a radical reaction.
