Decolourization of azo, anthraquinone and triphenylmethane dyes using aerobic granules: Acclimatization and long-term stability

چکیده
Abstract The long-term stability of aerobic granules is critical for decolourization different dyes in textile wastewater. Here, we investigated dye and the acetate-cultivated after exposure to dyes. Results show that can maintain excellent structure with presence azo triphenylmethane during a 200-day operation period, achieving biomass concentrations as high 8–12 g L−1 90% 100% efficiency, respectively. Aerobic granules, however, partially disintegrated anthraquinone, resulting efficiency ranging from 50 80% concentration low around 0.5 g L−1 due wash-out. study indicates granule much dependent on classes. enrichment specific species has not been affected by structure. rate microorganism ratio anthraquinone were 5–6.5 13.5–16.4 times, respectively, higher than those dyes, but total reactor performance poorer retention reactor. results suggest importance achieve better treatment dye-containing For first time, treating are reported here compared dye, which be used guide real wastewater containing azo, granules.

The Comparative Study on the Rapid Decolorization of Azo, Anthraquinone and Triphenylmethane Dyes by Anaerobic Sludge
An anaerobic sludge (AS), capable of decolorizing a variety of synthetic dyes, was acclimated and is reported here. The sludge presented a much better dye decolorizing ability than that of different individual strains. A broad spectrum of dyes could be decolorized by the sludge. Continuous decolorization tests showed that the sludge exhibited the ability to decolorize repeated additions of dye....

Synthetic dyes, azo dye in particular, are widely found in the effluents from textile industries. The persistence and toxicity of these compounds cause adverse impact in the receiving streams. A mixture of isolated cultures, from domestic sewage treatment plant was found to decolourize reactive azo dyes, Red RB, Blue M2B and Yellow, efficiently in the absence of added external nitrogen source. ...
متن کاملDecolorization of azo, triphenylmethane and anthraquinone dyes by a newly isolated Trametes sp. SQ01 and its laccase
A white-rot fungus, strain SQ01, was isolated from decayed wood in a temperate forest. The strain was identified as a member of genus Trametes, based on the morphological characteristics and a complete sequence analysis of its 18S rRNA gene and ITS region. Strain SQ01 was capable of decolorizing a variety of synthetic dyes, including azo, triphenylmethane, and anthraquinone dyes, with an optima...
