BACKGROUND Application of membrane technology to wastewater treatment has expanded over the last decades due to increasingly stringent legislation, greater opportunities for water reuse/recycling processes and continuing advancement in membrane technology. OBJECTIVES In the present study, a bench-scale submerged microfiltration membrane bioreactor (MBR) was used to assess the treatment of tex...

Textile industry comprises of dry mechanical and wet chemical processing,wet chemical process comprises of bleaches, dyeing , printing, & finishing. Dyeing is art of colouration to textiles.Dye get transferred to textile during dyeing. Dyeing operation is performed by the reaction between fiber and dyes. Some dyes are water soluble and some are water insoluble. Some fiber has affinity to dye; s...

Currently, the textile industry is one of the most important economic sectors in many countries. Besides, it is known as a major consumer of water and consequently one of the largest groups of industries causing intense water pollution. Chemicals, including surfactants, dyes, resins, dispersants agents, inorganic salts, etc., play a variety of functions during the textile processing and are pre...

Synthetic dyes are integral part of many industrial products. The effluents generated from textile dyeing units create major environmental problems and issues both in public and textile units. Industrial wastewater treatment is one of the major problems in the present scenario. Though, the physical and chemical methods offer some solutions to the problems, it is not affordable by the unit opera...

Azo dyes are one of the oldest industrially synthesized organic compounds characterized by presence of Azo bond (-N=N-) and are widely utilized as coloring agents in textile, leather, cosmetic, paint, plastic, paper, and food industries During textile processing, inefficiencies in dyeing result in large amounts of the dyestuff (varying from 2% loss when using basic dyes to a 50% loss when certa...

The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems. One of the main sources with severe pollution problems worldw...

After the dyeing process, part of the dyes used to color textile materials are not fixed into the substrate and are discharged into wastewater as residual dyes. In this study, a heterogeneous photocatalytic process combined with microfiltration has been investigated for the removal of C.I. Disperse Red 73 from synthetic textile effluents. The titanium dioxide (TiO2) Aeroxide P25 was selected as...

In the study of color matching in textile dyeing, regression algorithm is used to analyze the nonlinear relationship between the dye concentration and the color data in CIE-La*b* color space of dyeing sample, thereby providing theory basis for establishing mathematical model for textile dyeing. Statistical analysis is conducted on a number of experimental data and the model is tested by actual ...

Textile industry is one of the oldest and largest industries of India. Synthetic dyes are coloring agents mainly used in textile industries which generate a huge amount of wastewater in the process of dyeing. It is estimated that these industries discharge around 280,000 tons of dyes worldwide every year into the environment (Tom Sinoy and Anuradha Mohan, 2011). Discharge of these colored efflu...
