In this work, the efficiency of a photo-electrochemical method to remove color in textile dyeing effluents is discussed. The decolorization of a synthetic effluent containing a bi-functional reactive dye was carried out by applying an electrochemical treatment at different intensities (2 A, 5 A and 10 A), followed by ultraviolet irradiation. The combination of both treatments was optimized. The...

In order to search the degradability of kraft lignin, the potential bacterial strains Bacillus subtilis (GU193980) and Klebsiella pneumoniae (GU193981) were isolated, screened and applied in axenic and co-culture conditions. Results revealed that mixed culture showed better decolorization efficiency (80%) and reduction of pollution parameters (COD 73% and BOD 62%) than axenic culture. This indi...

This paper presents a decolorization method using gradient and saliency as the maintained features in the conversion to preserve the local and global visual perception. First, we construct a linear parametric mapping function of RGB color channels. Then, we calculate the feature value of each pixel in the color image and the parameterized grayscale image, the feature value integrates the pixel ...

The decolorization of industrial dyes was investigated using extracellular enzymes produced by 21 basidiomycetes, mainly edible mushrooms. Among the 27 dyes used in this study, nine were decolorized by over 40%. Most fungi decolorized Acid Orange 20, but they showed different specificities in the case of the other dyes. Determination of activity staining by native polyacrylamide gel electrophor...

UNLABELLED BACKGROUND In serious consideration of the worldwide environmental issues associated with the extensive use of the textile dyes and effluents generated thereof, the scientists across the world are in search for potential treatment technologies for their treatment. In such scenario the ligninolytic enzymes provide a potential alternative because they are cost effective, eco-friendl...

Introduction: Color is one of the indices of water pollution. Discharge of colored effluent can damage to receiving water resources. One of the proposed methods for treating dyeing wastewater is electrocoagulation process. In this study, decolorization of the real textile effluent by electrocoagulation process using monopolar iron electrodes was studied. Methods: This study was run experiment...

The removal of color from synthetic wastewater containing Congo red was experimentally investigated using electrocoagulation process. The effects of operational parameters such as current density, electrolysis time, electrolyte concentration, electrode distance, initial dye concentration, initial pH and temperature on color removal efficiency were investigated in this study. The tentative resul...

Abstract In this work, we evaluate the ability of a novel isolated bacteria identified as Bacillus thuringiensis RI16 (KM111604) to decolorize methyl red. Results showed its efficiency for treatment azo-dye-contaminated wastewaters under static conditions at pH values ranging from 7 9. The could tolerate higher doses dyes it was able up 1000 mg/L. For better red decolorization, potential use su...

The antioxidant properties of Galium verum L. (Lady’s Bedstraw) and Tragopogon pratensis subsp. pratensis (Goat’s beard) methanol extracts, from localities in Serbia were evaluated, through determination of total phenolics and flavonoids content, as well as DPPH • (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, ABTS •+ (2,2-azinobis-(3ethylbenzthiazoline-6-sulfonic acid) radical cation deco...
