Wastewater organic matter challenges wastewater treatment engineering, opposes partially unknown risk for recipient aquatic environment and reuse of water. \r\n\r\nThe primary aim of this thesis was to test the applicability of the use of HPSEC with UV and fluorescence detectors and characterize wastewater influent and effluent organic matter. Model compounds of typical protein- (tyrosine and tryptophan), fulvic- and humic-like matter were used. Samples of ten days were collected from Nen\u00e4inniemi WWTP in order to demonstrate the possibilities of the analysis method in a case study. Transferrability of the analysis method was tested to J\u00e4ms\u00e4 and Pieks\u00e4m\u00e4ki WWTPs.\r\n\r\nIn Nen\u00e4inniemi UV-254/DOC ratio increased 67 % (\u00b1 28) and BOD/COD ratio decreased 60 % (\u00b1 9). Total and fractional chromatogram peak area analysis of Nen\u00e4inniemi wastewater results indicated recalcitrant matter, especially in humic- and fulvic-like regions where average reduction of response was 1 % (\u00b1 5) and 27 % (\u00b1 7), respectively. Fluo-rescing components which resemble tyrosine (tyrosine-like) and tryptophan (tryptophan-like) were most efficiently reduced in treatment, with average of 84 % (\u00b1 7) and 74 % (\u00b1 3), respectively. Molecular size of ~ 500-1000 Da (fraction II) was most recalcitrant in all studied fluorescence and UV-254 responses, except in humic-like detection. \r\n\r\nMolecular size distribution in the same treatment plant within influent or effluent and effluents between compared WWTPs did not vary significantly, though differences in chromatogram peak areas were detected. Analysis method provided a reliable tool for EfOM tracing if dilution factor is 1:10. HPSEC with simultaneous fluorescence and UV detection can be used to efficiently characterize wastewater organic matter and EfOM. This method can be used as a complementary method in process and quality monitoring in WWTPs.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Salla Jokela (sahajoke) on 2018-05-05 10:54:35.606649.
