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 cause...

Dyeing is the process of adding color to textile products like fibers, yarns and fabrics. Dyeing is normally done in a special solution containing dyes and particular chemical material. After dyeing, dye molecules have uncut chemical bond with fiber molecules. The temperature and time controlling are two key factors in dyeing. The main aim of this project is to monitor and control the parameter...

The filtration characteristics of simulated dyeing effluents containing Acid Orange 7, sodium sulfate, and a pH buffer made of acetic acid and sodium acetate is described using a commercially available nanofiltration membrane. The original membrane filtration properties were characterized with deionized water to provide a baseline of membrane performance. At high volumetric concentration of the...

Bangladesh’s ready-made garment sectors have evolved to increase market share in the global textile supply chain. Textile heavily rely on energy and groundwater consumption during production; mainly, dyeing mills contribute carbon footprint water impact environment. become one of major industries responsible for continuous depletion levels severe pollution Reduction long-term key performance in...

Abstract: The colored organic or inorganic chemical compounds which can impart colour to other substance are the Dyes did significant applications in most industrial sectors like textile industry, leather paper plastic, foodstuff industry etc, color their products. Due large volume of dye use these businesses, a quantity wastewater containing organics is generated. Because insufficient dye-fibe...

African marigold [Tagetes erecta L.], a major source of carotenoids and Lutin, is grown as a cut flower and a garden flower, in addition to being grown for its medicinal values. Marigold flowers [Tagetes ], which are yellow to orange red in colour, are a rich source of lutein, a carotenoid pigment. Nowadays, Lutein is becoming an increasingly popular active ingredient used in the Food Industry ...

In this work, treatment of textile dye wastewater was carried in a batch reactor using Ganoderma lucidum. The characteristics of textile dye wastewater were studied. The effect of process parameters like pH, temperature, agitation speed and dye wastewater concentration on dye decolourization and degradation were studied. These parameters were optimized using response surface methodology (RSM). ...
