The oxidation of organic compounds and color removal of a synthetic dyeing effluent when treated with a combination of Fenton’s Reagent and biological oxidation in a sequencing batch reactor was evaluated in this work. A central composite design approach was used to find the best conditions of temperature, hydrogen peroxide and ferrous ion concentrations that maximize color and dissolved organi...
Erythrocyte abnormality test has been used to detect the genotoxic effect of dyeing industry effluent on the fish. The 96h LC50 of effluent against Cirrhinus mrigala was calculated by Finney method and three sublethal concentrations 24.48%, 12.24% and 6.12% were made. Fishes were kept in concentrations and blood was smeared after 24h, 48h, 72h and 96h. Eleven types of erythrocyte abnormalities ...
Bacillus subtilis C3, a commercial textile dye-decolorizing and -degrading bacterium, was isolated from the common effluent treatment plant (CEPT) of the Jetpur textile dyeing and printing industrial sector situated in the district of Rajkot, Gujarat, India. Here, we present the annotated 4.18-Mb draft genome sequence of B. subtilis C3, providing information about the metabolic pathways involve...
Rapid industrialization and urbanization results in the discharge of large amounts of waste to the environment, which in turn creates more pollution (Senan and Abraham, 2004). Synthetic dyes are extensively used in textile dyeing, paper printing, color photography, pharmaceutical, food, cosmetics and other industries. During textile dyeing, the amount of dye lost in effluent is dependent upon t...
The objective of this project was to biologically renovate reactive dyebaths and reuse the high-salt containing mixture in the dyeing process. This approach accomplishes two goals: (a) elimination of the color from the plant effluent; and (b) reuse of the renovated process water and salts, thus leading to final wastewater volume reduction, and water, as well as salt conservation. Nine commercia...
In this work, a synthetic textile effluent containing a reactive dye (C.I. Reactive Orange 4) was treated in an electrochemical cell with titanium covered by platinum oxide (Ti/PtOx) electrodes to remove color. The discolored effluent was mixed with other textile mill process effluents (scouring, bleaching, washing, etc.), according to the rate of each effluent in the mill, and was submitted to...
The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...
Treatment of a Textile Effluent from Dyeing with Cochineal Extracts Using Trametes versicolor Fungus
Trametes versicolor (Tv) fungus can degrade synthetic dyes that contain azo groups, anthraquinone, triphenylmethane polymers, and heterocyclic groups. However, no references have been found related to the degradation of natural dyes, such as the carminic acid that is contained in the cochineal extract. Experiments to determine the decolorization of the effluent used in the cotton dyeing process...
