Özet:

The existing study has evaluated the filtration performance of textile industry waste with various nanofiltration (NF) and reverse ozmoz (TO) membranes. The studies were performed under different pressures with the dead end filtration arrangement (10, 15, 20 and 25 bar). Tested nanofiltration membranes are NF90, NF270, NFTS40, NFXN45, NFDK and NFDL. The reverse ozmoz membranes are ROX201, ROBW30FR and ROACM5. The highest tolerance per pressure for nanofiltration membranes is obtained by the NF270 membrane, which is 5.95 L/(m2.h.Bar). Although other nanofiltration membranes have reached a higher passivity value with Nazaran NF270, the highest reduction in the time of the unit of passivity has also been in this membrane. The starting passivity is 12.41 L/(m2.h) under 15 bar pressure. At the end of the 1 hour test time, it fell to 4.41 L/m2.h.Bar. In the reverse ozmoz membranes, the highest passivity value was identified with the ROACM5 membrane as 2.96 L/(m2.h.Bar). The highest passivity decline was observed again in the ROACM5 membrane (about 4.14 L/(m2.h.Bar) to 2.48 L/(m2.h.Bar) for both 10 and 15 bar pressure). The highest color, conductivity and COI deduction for nanofiltration membranes were found, NF90 to 4515 μS/cm conductivity; 518 Pt-Co color and 119 mg/L COI input conditions were found at >95%, >99% and >97% respectively. When a higher conductivity removal is requested, the reverse ozmoz membranes should be used. For the tested reverse ozmoz membranes, the conductivity discharge percentages are >97%, >98% and >98% respectively for ROBW30FR, ROX201 and ROACM5 in the same waste.
