This result demonstrated that the static condition was necessary for the decolorization of ts17, as it is also the case for most of the microbial species for the decolorization of azo dyes. The general mechanism for the azo dye degradation is through reduction of azo bond by azoreductase (Chacko and Subramaniam, 2011).

In the present study, an ozonation system consisting of air compressor, ozone generator, gas flow meter and bubble column reactor was operated to evaluate the behavior of removing color from an aqueous solution containing the reactive Corafix BR Red azo dye. The influence of parameters solution initial pH and initial dye concentration on the ozonation was investigated in order to optimize the operational conditions.
