One of the features of the textile dyeing industry is using large quantities of water and releasing large amounts of pollutants. Processes such as dyeing are the main cause of pollution in the textile industry, in which a number of water, chemicals and dyes are used for producing textile products. The textile dyeing wastewater mainly contains pollutants such as toxic organics, dyes, suspended substances, BOD5 and COD.
