Decolorization and Degradation of Erioglaucine (Acid Blue ...

Erioglaucine (CAS No. 3844-45-9) is a widely used acid aminotriphenylmethane dye of an intense blue color. Erioglaucine containing wastewater streams are not affected by activated sludge treatment plants. Therefore, pretreatment is necessary before discharging. In the industry the standard procedure is to use NaOCl for this purpose.

Advanced Oxidation Processes (AOPs) have been used as emerging ,wastewater, treatment technologies which can effectively handle various hazardous organics in ,wastewater, and groundwater. This study examined the photodecolorization of azo dyes in aqueous solution by combined UV, individual and coupled photocatalysts. The model substrate employed in this work was C.I. ,Acid, Yellow 23 (AY23) …

Sonolytic Decolorization of Textile Wastewater Containing ...

The rate of sonolytic decolorization followed first‐order kinetics for the textile wastewater containing RB5 and CR. The results of this study indicate that, with an increase in the sonication time, the decolorization efficiency increases for the textile wastewater containing …

Bacterial Influence on Textile Wastewater Decolorization
Bacterial Influence on Textile Wastewater Decolorization

The ,decolorization of acid, orange 7 by Bur. cepace-TN5 after 24 hours showed that the best ,decolorization, percentage was at inoculum size (2 ml) and the lowest value was for inoculum size 0.2 ml. Results recorded after 12 hours showed that inoculum size 3 ml gave the highest color removal, and other inocula sizes gave nearly the same value of ,decolorization, except for the inoculum size 1 ml, where the lowest value of ,decolorization, …

Decolorization of Dyeing Wastewater Using Polymeric ...

29/2/2012, · Decolourisation is a result of two mechanisms (adsorption and ion exchange) and is influenced by many factors including dye/adsorbent interaction, adsorbent’s surface area, particle size, temperature, pH and contact time. Physical adsorption occurs when weak interparticle bonds exist between the adsorbate and adsorbent.
