- The removal of five reactive dyes varying in molecular weight (Reactive Orange 16, Remazol Brilliant Blue R, Reactive Orange 20, Reactive Black 5, Reactive Red 120) was evaluated by using flat ultrafiltration membranes made of polyethersulfone (PES) and regenerated cellulose (C) characterized by various cut-off values (5, 10, and 30 kDa). The ultrafiltration process was performed in a dead-end mode under the transmembrane pressure range of 0.05–0.2 MPa. Dye concentration in model solutions was equal to 100 mg/dm3. The separation efficiency of all tested dyes was strongly dependent on the membrane type and the membrane cut-off, as well as on the applied pressure. Unexpectedly, the molecular weight of the tested reactive dyes had a minor impact on the dye removal effectiveness. The ultrafiltration membranes made of polyethersulfone and regenerated cellulose can be used in reactive dye removal on the condition that the membrane cut-off is not higher than 10 kDa. The PES and C membranes enable the separation of reactive dyes by 80–97%, and 45–89%, respectively.
