In this work, decolorization of C.I.Reactive Black5 (RB5) was carried out under batch anaerobic
condition using activated sludge. The effects of medium composition on RB5 decolourisation
efficiency were investigated by employing statistical design of experiments. The Plackett-Burman
design was used to determine which medium components had a positive effect on decolorization
of this azo reactive dye. Statistical analysis of the results showed that FeCl2.4H2O, MgSO4.7H2O,
and MnCl2.4H2O had a positive contribution to azo dye decolorization. A Box-Behken design was
performed to obtain the optimum concentration of these three media components with respect to
dye decolourisation.
