Abstract (EN): Textile industry constitutes nowadays one the largest consumers of water, and consequently the wastewater reuse can be a profitable operation. In this study, the decontamination of pure dyes solutions (Remazol Turquoise Blue G, Remazol Yellow GR and Lanaset Blue 2R) and synthetic textile wastewaters was evaluated in a nanofiltration (NF) cross-flow cell, using polyamide NF membranes, NF90 and DK, with molecular weight cut-off between 200-400 Da and 150-300 Da, respectively. Permeate flux and the color reduction were evaluated for the different dye solutions under different temperature and pH conditions and, NaCl, wetting and dispersant concentrations. DK membrane showed the best results in terms of permeate flux for all the dye solutions tested. The highest permeate flux was achieved for higher temperatures under acidic to neutral pHs values, resulting in almost 100 % color removal for all situations.
