The textile industry is characterized by the fact that its activity requires a high consumption of water, energy and auxiliary chemical products. This is translated into the generation of a large amount of wastewater, with high concentrations of dyes, biodegradable and refractory organic pollutants, suspended matter, surfactants, salts and chlorinated compounds. In addition, because in the great majority of cases production is intermittent, there is a significant variability in the amount of the wastewater generated and the nature of its contamination. These characteristics make it an industrial effluent that is difficult to treat.
The regulatory requirements and the need to save energy and reuse water in industry make it necessary to develop new processes that will enable us to eliminate the water pollution and make it possible to reincorporate the effluent in the production process.
