In the present work, rock dust was evaluated as an adsorbent and heterogeneous photocatalyst in discoloration of Basazol Yellow 46 L dye, which is widely used dyeing molded pulp packages. Although produced large quantities quarries a byproduct exploration, little known about its application photocatalyst. Rock characterized by XRD, SEM/EDS, photoacoustic spectroscopy, N2 physisorption had photo...

Water contamination with large amounts of industrial textile coloured effluents is an environmental concern. For the treatment of textile effluents, white-rot fungi have received extensive attention due to their powerful capability to produce oxidative (e.g., ligninolytic) enzymes. In addition, other groups of fungi, such as species of Aspergillus and Trichoderma, have also been used for textil...

Article history: Received 30 August 2017 Accepted 18 September 2017 Available online 02 October 2017 The textile industry is a field which has strong environmental impacts due its high consumption of water and emission of pollutants, specially the dyes. The dyes are organic or synthetic substances which alter the physicochemical characteristics of the water body in which they are released, incr...

In the present study the treatment efficiency of O3 and UV+O3 processes were compared for the oxidation of simulated dyebath effluent containing a mixture of a reactive dye (C.I. Reactive Blue 19) and various dye auxiliary chemicals. The color, COD and TOC removal rates were assessed for different processes. The effect of initial dye concentration and presence of sodium hydroxide and sodium car...

A bacteria strain Bacillus thuringiensis RUN1identifiedby 16s RNA gene phylogenetic analysiswas used to decolorize malachite green, a triphenylmethane dye in simulated wastewater. The ability of the organism produce extracellular laccase and degrade were also investigated. Results showed that decolorized (84.67 ± 1.19 %) green at 40 mgl-1 within 6 h; decolorization was associated production by ...

A potential bacterial strain PMS82, capable of degrading an azo dye Acid orange as a sole source of carbon was isolated from common effluent treatment plant of Ankleshwar, India. The 16S rDNA sequence and phenotypic characteristics indicated that an isolated organism as Bacillus megaterium PMS82. This strain exhibited complete decolorization of Acid orange (100 mg/L) within 16 h, while maximall...

The application of synthetic dyes in various industries improved the aesthetic properties of the products, but the discharge of dye-containing effluent into water bodies leads to serious environmental problems. Till date, colour removal from effluent is still a challenge due to the absence of economically attractive treatments. In this study, decolourization of a synthetic dye – Remazol brillia...

A dye-decolorizing bacterium was isolated from a soil sample and identified as Bacillus thuringiensis using 16S rRNA sequencing. The bacterium was able to decolorize three different textile dyes, namely, Reactive blue 13, Reactive red 58, and Reactive yellow 42, and a real dyehouse effluent up to 80-95% within 6 h. Some non-textile industrially important dyes were also decolorized to different ...
