TLDR
In this article, the anaerobic treatability of reactive black 5 in an an-aerobic/aerobic sequential process was investigated in a laboratory scale upflow anaerobatic sludge blanket (UASB) reactor/completely stirred tank (CSTR) with different organic loadings and hydraulic retention times (HRT).About:

Combined anaerobic-aerobic treatment of azo dyes--a short review of bioreactor studies.
TL;DR: Analytical data indicate that many of the aromatic amines were removed from the wastewater, and although the limited amount of available toxicity data all show far-reaching detoxification during aerobic treatment, it is clear that not all aromatic amine can be completely mineralized.

Removal of Synthetic Textile Dyes From Wastewaters: A Critical Review on Present Treatment Technologies
Kamaljit Singh,Sucharita Arora +1 more
TL;DR: In this article, a comparison of the present decolorization/degradation techniques for water-sensitized azo dyes is presented, where the hierarchy of reduce, reuse, and degrade is adopted and measures are taken to remove color from the industrial discharge.

Accelerated decolorization of structurally different azo dyes by newly isolated bacterial strains
TL;DR: Six bacterial strains are found to be the most efficient azo-dye degrading bacteria that have been described and may have practical application for biological treatment of dye-polluted wastewater streams.

Anaerobic Biotechnology for Industrial Wastewaters
TL;DR: This book provides technical and economical information on how to develop the most feasible total environmental control program that can benefit both process industry and local municipalities, as well as decision-makers on energy and environmental policies.
Journal ArticleDOI
Microbial process for the decolorization of textile effluent containing azo, diazo and reactive dyes
TL;DR: The decolorization of some component dyes of the effluent and of a mixture of dyes was achieved under anaerobic conditions, indicating that the bacteria were able to break the chromophoric bonds in the dye molecules.
Journal Article
Microbial decolourisation of a reactive azo dye under anaerobic conditions
TL;DR: A toxicity assay showed that C.I. Reactive Red 141 was inhibitory to the anaerobic microbial community at concentrations >100 mg/l, but that prior exposure of the biomass to the dye increased the resistance to previously inhibitory dye concentrations.

Determination of bicarbonate and total volatile acid concentration in anaerobic digesters using a simple titration
G. K. Anderson,G. Yang +1 more
TL;DR: In this paper, a simple, alkalimetric method is described that can be used to determine bicarbonate and total volatile fatty acid concentrations in anaerobic digesters by a two-stage sequential titration.
Journal ArticleDOI
Azo-dye degradation in an anaerobic-aerobic treatment system operating on simulated textile effluent.
TL;DR: Although only a simple qualitative HPLC method was used, colour removal, toxicity and TON removal all support its usefulness in analysing biotreatment of azo dyes.
