The textile industry wastewater is highly harmful to the environment when it is discharged in
its raw state, since it might contain dyes, surfactants, and other dissolved compounds that …

The soluble redox mediator had been employed for catalyzing anaerobic bio-reduction of
recalcitrant contaminants such as azo compounds (mainly azo dyes), nitroaromatics …

Sequential anaerobic and aerobic processes have been recommended to treat textile
wastewater reliably. In this work, the focus was on finding an energetically more competitive …

The effects of discontinuous micro-aeration on the biotransformation of the tetra-azo dye
Direct Black 22 (DB22) and of its anaerobic by-products (aromatic amines) were tested …

Real textile wastewater containing high salinity (up to 12.6 g· kg− 1) and surfactant (up to 5.9
mg· L− 1 of linear alkylbenzene sulfonate–LAS) was submitted to biological treatment for …

Azo dye reduction by syntrophic microbial communities is still unclear, with conflicting
observations reported in the literature. In this study, the biodegradation mechanism of a …

In the present study, we evaluate the behavior of real textile wastewater treatment using a
system composed of two sequential pilot-scale reactors (anaerobic followed by aerobic) …

A heterotrophic sulfur autotrophic integrated fluidized bed reactor was established for
simultaneous and efficient removal of ClO 4− and NO 3− from water. The optimum operating …

Anaerobic treatment of azo dyes is particularly challenging in the case of wastewaters
containing sulfate. We studied the use of multiple stage anaerobic system to minimize the …

BACKGROUND Textile wastewater is known for its polluting potential and toxicity.
Biological, affordable treatments are especially desirable in developing countries to fulfill …
