Abstract

The growing population of the world and the progressive adoption of an industrialist lifestyle based, inevitably, have caused an increase in the anthropogenic impact on the biosphere. The textile industries are the most important industries in Asia and their numbers have increased. These industries have shown a significant increase in use of organic synthetic complex dyes as a coloring material. Wastewater printing and dyeing units are often rich in color, which contains residues of reactive dyes and chemicals, and requires proper treatment before being released into the environment. These compounds can be released to effluent water during washing. Examples of these compounds include surfactants, sizing, coatings and additive finishes. Sizing Compounds such as starch contribute to a higher demand for biological oxygen and the demand for chemical oxygen of the wastewater current.
