Anaerobic treatment of Azo-dye under batch conditions

Anaerobic treatment system was used for determination of colour removal under batch conditions. Azo-dye (Reactive Black 5, RB 5) with glucose as a carbon source was used as a synthetic wastewater. The decolourization process follows first order kinetics with respect to RB 5 azo-dye concentration in batch conditions. Decolourization rate constant (k1) value for dye concentration of 150 mgL-1 was 0.1751 h-1 in the batch experimental study performed with RB 5. Maximum Reactive Black 5 removal efficiency was obtained after 24 hour (99%) under batch experimental condition.
