TQ15000057

The aim of the project is to develop an applicable and sustainable technology for recycling used dye baths from dyeing natural fabrics within the framework of experimental development and industrial research. Such baths contain, in addition to a high concentration of NaCl, unused dyes and auxiliary textile agents (surfactants). The technology we are developing will enable the recycling of the aqueous NaCl solution in the spirit of the “Zero Liquid Discharge” philosophy, thereby saving water and salt and reducing the burden of discharged water with parameters such as RAS, COD, and possibly AOX. The project will also explore the possibility of further utilizing the sludge produced from the separation of dyes and surfactants.
