20.500.12556/DKUM-27202 Wastewater treatment after reactive printing Membrane filtration of wastewater after textile printing with reactive dyes isdescribed. The wastewater from a Slovenian factory, whose output is approx. 80% reactive dyes printed and dyed on cotton, was studied. In particular, the presence of urea, sodium alginate, oxidation agent and reactive dyes, used forthe printing paste preparation, in the wastewater was studied. Chemical analyses of actual, non-purified, wastewater showed that many Slovenian regulations were exceeded. The study of membrane filtration is based on a pilot wastewater treatment plantČ ultrafiltration (UF) and reverse osmosis (RO) units. The quality of the wastewater was improved by ultrafiltration, butits effluent still does not conform to the specification of concentration limits for emission into water. Permeate coming from RO meets the required specification and, therefore, could be re-used in the washing process of printed textiles. textile printing reactive dyes wastewater treatment membrane filtration pilot plant tiskanje tekstilij reaktivna barvila odpadne vode membranska filtracija čiščenje odpadnih vod pilotska naprava true false false Angleški jezik Angleški jezik Neznano 2012-06-01 10:04:11 2012-06-01 10:04:11 2022-04-15 03:43:37 2019-07-10 12:12:49 2005 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677.027.5:628.3 8941846 0143-7208 URN:SI:UM:DK:UFWOZZCS http://dx.doi.org/10.1016/j.dyepig.2004.04.001 1 https://dk.um.si/Dokument.php?lang=slv&id=36457 Fakulteta za strojništvo 0 0 0
