The feasibility of sequential anaerobic–aerobic treatment for complete dye degradation was
evaluated using three azo dyes, namely Remazol Red RR, Remazol Blue RR and Remazol …

Decolorisation of azo dyes during biological effluent treatment can involve both adsorption
to cell biomass and degradation by azo-bond reduction during anaerobic digestion …

Decolorization of two monoazo dyes, acid orange 6 (AO6) and acid orange 7 (AO7), were
studied in sequential fixed-film anaerobic batch reactor (SFABR) with varying dye …

Dyes are synthetic organic compounds widely used in various industries such as, textile,

The feasibility of thermophilic (55° C) anaerobic treatment applied to colour removal of a
triazine contained reactive azo dye was investigated in two 0.53 l expanded granular sludge …

The most logical concept for the removal of azo dyes in biological wastewater treatment
systems is based on anaerobic treatment, for the reductive cleavage of the dyes' azo …

A great number of the reported examples of azo dye biodegradation comprise two main
steps, the reductive cleavage of the azo bond under anaerobic conditions and the …

Azo dyes represent the largest class of dyes in use today. Current environmental concern
with these dyes revolves around the potential carcinogenic health risk presented by these …

In this work, the anaerobic period of an anaerobic–aerobic sequencing batch reactor was
found to allow the reductive decolourisation of azo dyes. 1-l reactors were operated in 24-h …
