20.500.12556/DKUM-27448 Residual dyebath purification using a system of constructed wetland A constructed wetland model, comprising two different substrate mixtures, was used to purify textile dyebath wastewater. Three laboratory prepared wastewaters containing three commercial dyes of different classes and chemicalconstitution (one vat and two reactive dyes), different chemicals (NaOH, NaCl) and auxiliaries (migration inhibitor, sequestering, defoaming andwetting agents) were employed. Purifying efficiency was verified by measuring pollution parameters, such as absorbance, pH, total organic carbon (TOC), chemical oxygen demand (COD) and electrical conductivity (EC). It was found that the constructed wetland model reduced dye concentration by up to 70%, lowered the TOC and COD values up to 88%, electrical conductivity up to 60% and pH from 12 to 7.6. textile dyeing reactive dyes vat dyes wastewater treatment constructed wetland model biological treatment purification barvanje tekstilij reaktivna barvila vat dye čiščenje odpadnih vod rastlinske čistilne naprave biološko čiščenje true false false Angleški jezik Angleški jezik Neznano 2012-06-01 11:15:39 2012-06-01 11:15:39 2022-04-15 03:44:28 2019-07-10 12:17:11 2007 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677.027.4:628.35 10945558 0143-7208 URN:SI:UM:DK:TAZSCCKP http://dx.doi.org/10.1016/j.dyepig.2006.10.007 1 https://dk.um.si/Dokument.php?lang=slv&id=36748 Fakulteta za strojništvo 0 0 0
