20.500.12556/DKUM-27461 The removal of reactive dye printing compounds using nanofiltration A synthetically prepared reactive dye print wastewater, mimicking real wastewater obtained from a local textile mill, was treated by nanofiltration using an NFT-50 membrane in a plate and frame module configuration at different cross-flow velocities (0.4, 0.6 and 0.8 m/s) and pressures (2-15 bar). The nanofiltration membrane was evaluated for membrane fouling, permeate flux and its suitability for removing colour, conductivity, Na+ ions and COD as a function of operating pressure and feed concentration. The permeate separation efficiency was monitored by measuring the removal efficiency of colour, conductivity, Na+ ions and COD retention. The membrane achieved high dye retention for each of the four dyes (from 99.4 to 99.9%) and electrolytes used (63-73%). The retention of organic substances varied between 20 and 50%, depending on the pressure used; higher retentions were achieved at higher pressure and by using higher cross-flow velocities. nanofiltration nanofitration membranes wastewater after reactive printing reactive dye concentration polarization nanofiltracija nanofiltracijske membrane odpadne vode po reaktivnem tiskanju reaktivna barvila koncentracijska polarizacija true false false Angleški jezik Angleški jezik Neznano 2012-06-01 11:17:35 2012-06-01 11:17:35 2022-04-15 03:44:53 2019-07-10 12:17:27 2007 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677.017:547 11062038 0143-7208 URN:SI:UM:DK:TPXZWQKN http://dx.doi.org/10.1016/j.dyepig.2006.11.003 1 https://dk.um.si/Dokument.php?lang=slv&id=36761 Fakulteta za strojništvo 0 0 0
