Abstract

Abstract: A set of scale-up technological process of flow photoassisted degradation of dye wastewaters was designed. Acid Red G and Direct Light Proof Scarlet 4BS wastewaters were continuously degradated in aqueous suspensions of titanium dioxide made in China with the above process. Experimental data show that CODcr of dye wastewaters was reduced and the colour disappeared. The catalyst could be completely separated from water phase.

Key words: photocatalytic degradation, treatment of wastewater, tianium dioxide
