In principle, for separation of salt from concentrated brine solutions, desahnation techniques common for seawater are suitable. Koyuncu et al. (2004) reported studies on reactive dye/sodium chloride separation using nanofiltration membranes made from polysulfone-polyamide. The emphasis of this research, however, was more directed towards the quality of the purified water than on reclamation of salt or dye. Wenzel et al. (1996) suggested re-use of the bath of a reactive dyeing process containing all auxiliaries after the hydrolyzed reactive dye has been removed by adsorption on activated carbon. The dyes were degraded in an anaerobic digester.
