Industrial development worldwide has led to an increase in the amount of wastewater production leading to a considerable decrease in levels and quality of the natural water in the ecosystem. Textile dyes are an important class of pollutants in natural water ecosystem. Textile dyes are molecules designed to impart a permanent colour to textile fabrics. Effluent from textile dyeing units contain ...
A bacterial consortium BMP1/SDSC/01 consisting of six isolates was isolated from textile effected soil, sludge, and textile effluent from Hudiara drain near Nishat Mills Limited, Ferozepur Road, Lahore, Pakistan. It was selected because of being capable of degrading and detoxifying red, green, black, and yellow textile dyes. The pH and supplements were optimized to enhance the decolorization ab...
In Rajasthan state particularly, textile mills represent an important economic sector. Pali district in Rajasthan has got largest number of textile industries in the State i.e.989 units, mostly engaged in cotton and synthetic textile printing and dyeing. These industries liberate a variety of chemicals, dyes, acids and alkalis besides other toxic compounds like heavy metals, which are known for...
Clothing textiles come under the category of other commodities pursuant to the Foods and Other Commodities Act. They require neither notification nor marketing authorisation which means that the public authorities do not have information about individual textile auxiliaries or dyes used. The working group "Health Assessment of Textile Auxiliaries and Dyes" within the working group "Textiles" of...
Textile industry is one of the biggest industries of the world. Workers engaged in the textile industries around the world are exposed to different sets of chemicals including dyes, solvents, finishing chemicals and metals including Cu, Cr, Ni etc. Many of these chemicals including dyes have been identified as carcinogenic to humans. The exposure of the workers to such carcinogenic chemicals re...
A strain LN07 with high laccase yield was identified as basidiomycete fungus Lepista nuda from which a white laccase without type I copper was purified and characterized. The laccase was a monomeric protein with a molecular mass of 56 kDa. Its N-terminal amino acid sequence was AIGPAADLHIVNKDISPDGF. Besides, eight inner peptide sequences were determined and lac4, lac5 and lac6 sequences were in...
Water plays a vital and essential role in our ecosystem. This natural resource is becoming scarce, making its availability a major social and economic concern. Use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. About 17 - 20% of freshwater pollution is caused by textile effluents. These effluents are recalcitrant to biodegradation and cau...
backgroud and purpose: dye is one of the problems of industrial effluent such as textile industries. the dyes can be removed by various methods. therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. materials and methods: this research was a lab study. activated red mud was used as an adsorbent to remove reactive r...
