Treatment of synthetic wastewater containing textile dyes with experimental constructed wetlands
… has resulted in the rapid growth of textile industries in developing countries, leading to a high rise in the overall discharge of a broad range of pollutants. Amongst these pollutants is dye wastewater, which frequently has mutagenic and carcinogenic effects on humans and animals, …

Contact Allergy to Textile Dyes - Clinical and Chemical Studies on Disperse Dyes
Disperse dyes are common sensitizers among textile dyes. Contact allergy to disperse dyes has been documented in studies carried out in southern Europe, however, corresponding studies have not been performed in the Scandinavian countries. The aim of this study was thus to evaluate the prevalence of …

Azo textile dyes wastewater treatment with constructed wetlands : design and operation of experimental vertical-flow constructed wetlands applied for the treatment of azo textile dyes (with/without artificial wastewater)
… role as natural purification systems. Textile industry processes are among the most environmentally unsustainable industrial processes, because they produce coloured effluents in large quantities polluting water. The aim of this study is to assess the performance of VFCWs to treat two …

Contact allergy to textile dyes. Clinical and experimental studies on disperse azo dyes
Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in …

Investigation of Color Removal by Chemical Oxidation for Three Reactive Textile Dyes and Spent Textile Dye Wastewater
… (UV/H₂O₂) for decolorizing three reactive azo dyes (sultan red, indigo blue and cypress green) and treated textile-manufacturing wastewater. The objective was to determine the best treatment for reducing color to the Virginia Pollutant Discharge Elimination System (VPDES) permit level of 300 …

A Comparative Study on the Efficacy of Modified Clay Soil for the Decolouration of Acidic and Basic Textile Dyes: A Case Study
Dyes play a crucial role in the production of various products, including paper, plastics, and leather. However, their release into the environment leads to pollution and poses health risks to both humans and animals. Therefore, it is essential to treat dye-containing effluents before they are …

Anaerobic/aerobic degradation of a textile dye wastewater
… have led to the development of new, more stable textile dyes. These dyes, many of the azo type, are often incompletely degraded/removed in wastewater treatment plants, leading to the discharge of highly colored effluents to rivers and streams. Concerns by downstream users of that water have led …

Monitoring for sulfonated azo dyes and their degradation products in industrial and municipal wastewater
… azo compounds are one of the most commonly used textile dyes. They pose an environmental problem because they can be difficult to degrade in municipal and industrial treatment systems and can cause effluent wastewaters to violate color standards. Methods were developed to monitor for three …

Biological treatment and recycling of textile processing effluents
… capable of decolourising a range of selected textile dyes was isolated and used to develop a continuous culture system for the treatment of textile dye effluents. The bioprocess was optimised using biomass growth supports. The presence of a carbon source such as soluble wheat starch (0.2 % …

Transient Fashion: A Transdisciplinary Framework For Developing Casein-Based Materials Within A Regenerative Textile Economy
… This issue is acutely evident in fashion and textiles, where the phenomenon of ‘fast fashion’ has driven demand to unprecedented levels. Sustainable practices within the Fashion and Textile Industry (FTI) often focus on implementing a circular economy model to minimise waste by maximising …

Biomimetic emulators of high potential peroxygenases: Implications in bioremediation and metabolic studies
… oxidation of several pollutants such as durable textile dyes and inorganic sulfides, has been attempted with quite promising results, and some findings open the way toward industrial scaling-up. Accordingly, the inexpensiveness of the synthesis and the mild operational conditions allow these …

Supported Metalloporphines as novel and bioinspired Lignolytic Peroxidase-like Catalysts
… bleaching of several pollutant and durable textile dyes has been attempted with similar promising results, resulting particularly suitable for industrial scaling up. Accordingly, the inexpensiveness of the synthesis and the mild operational conditions allow these adducts to be proposed as …
