This review discusses cotton textile processing and methods of treating effluent in the textile industry. Several countries, including India, have introduced strict ecological standards for textile industries. With more stringent controls expected in the future, it is essential that control measures be implemented to minimize effluent problems. Industrial textile processing comprises pretreatme...

The application of synthetic colors in textile industries and their entry into the water and groundwater is an environmental problem because of being very toxic material. The synthetic colors which are used in textile dyeing (plyacrilic and polyester) are usually dispersing colorants. They derive the azo and anthraquinone chemicals. Electro-Fenton process is an efficient technique which can deg...

In textile industry during the dyeing process roughly 10% of synthetic dyes were used and let into the wastewater. Among all dyestuff Azo dyes occupies in majority, because they are extensively used in the textile, paper, food, leather, cosmetics and pharmaceutical industries. They represent chief polluting components ranging from inorganic compounds to polymers and organic elements. However pr...
