“…Similarly to the results found in this work, protein and tryptophan-like substances, which represent the most biodegradable fraction of DOM, revealed the highest removal, whereas lower elimination rates were observed for fulvic and humiclike fluorescence components [44,50]. Studies on DOM removal by fluorescence spectroscopy in conventional WWTPs have also reported the highest removal (40-99%) for fluorescing substances in the region of EEM with emission < 380 nm (i.e., protein, tryptophan-like and tyrosine-like fluorescence) and the observed removal rates were similar under aerobic or anoxic/anaerobic conditions [16,22,49,[51][52][53]. On the contrary, lower removals (10-30%) were reported for fulvic and humic-like components and sometimes production of fluorescence intensities were observed for components sensitive to microbial activity under both aerobic and anoxic/anaerobic conditions [16,22,49,[51][52][53].…”

It has been suggested that microbial product and fulvic-like fluorescence components are either potentially produced by microbial activity during the process or are recalcitrant to decomposition [14,53,54].…”

The elimination of organic carbon, nitrogen, five emerging organic contaminants (EOCs) and fluorescence signature was evaluated in two treatment lines comprising different constructed wetland (CW) configurations: (i) partially saturated vertical subsurface flow (SVF) wetland (treatment line 1) and (ii) unsaturated vertical subsurface flow (UVF), horizontal subsurface flow (HF) and free water surface (FWS) wetlands in series (treatment line 2). Results showed important differences between the different CW configurations. The highest removal of BOD5 (81%), COD (67%), TOC (72%) and fluorescing organic matter were observed in the UVF wetland, whereas the HF and FWS wetlands were the most efficient units for total nitrogen removal (60 and 69%, respectively).The SVF wetland showed a greater performance in the reduction of total nitrogen than the UVF bed (52 vs 35%). In addition, the SVF wetland exhibited a higher removal of the EOCs caffeine (95 vs 90%), trimethoprim (99 vs 87%) and sulfamethoxazole (64 vs 4%), as opposed to DEET (34 vs 63%), whose removal was superior in the UVF unit. Sucralose was negligibly removed in all the CWs. PARAFAC analysis of fluorescence measurements revealed that the proteinaceous tryptophan-like fluorescent component was the most highly removed one in all the investigated CWs (>28%) and, particularly, in the UVF wetland (66%), whereas humic and fulvic-like components resulted recalcitrant to decomposition. Increases of fluorescence intensities were often observed for fulvic-like substances in CWs operating with saturation of the bed, and these were particularly relevant in the SVF unit. Finally, important correlations (r>0.7) between the tryptophanlike fluorescent component and the water quality parameters COD and BOD5 suggest fluorescence spectroscopy as an useful monitoring tool for water treatment efficiency in CW systems.

“…The C1 component was thus considered a by-product associated with microbial growth. The tryptophan-like C2 component was reported to be resistant to filtration, but susceptible to biodegradation, therefore it should be soluble and biodegradable [27,29,30]. The tyrosine-like C3 component was reported to be a soluble microbial product (SMP) commonly present in recycled wastewater [27,[31][32][33].…”

“…It could be removed by physico-chemical treatments, such as coagulation, but not entirely with a biological treatment system. The fulvic-like C4 component was reported to be recalcitrant in a conventional activated sludge system, because it is considered non-biodegradable [11,29,30]. …”

Municipal wastewater treatment plants (WWTPs) in Korea collect and treat not only domestic wastewater, but also discharge from industrial complexes. However, some industrial discharges contain a large amount of non-biodegradable organic matter, which cannot be treated properly in a conventional biological WWTP. This study aimed to investigate the characteristics and biodegradability of the wastewater organic matter contained in the industrial discharges and to examine the fate of the industrial discharges in a biological WWTP. In contrast to most previous studies targeting a specific group of organic compounds or traditional water quality indices, such as biological oxygen demand (BOD) and chemical oxygen demand (COD), this study was purposed to quantify and characterize the biodegradable and nonbiodegradable fractions of the wastewater organic matter. Chemical oxygen demand (COD) fractionation tests and fluorescence spectroscopy revealed that the industrial discharge from dyeing or pulp mill factories contained more non-biodegradable soluble organic matter than did the domestic wastewater. Statistical analysis on the WWTPs' monitoring data indicated that the industrial discharge containing non-biodegradable soluble organic matter was not treated effectively in a biological WWTP, but was escaping from the system. Thus, industrial discharge that contained non-biodegradable soluble organic matter was a major factor in the decrease in biodegradability of the discharge, affecting the ultimate fate of wastewater organic matter in a biological WWTP. Further application of COD fractionation and fluorescence spectroscopy to wastewaters, with various industrial discharges, will help scientists and engineers to better design and operate a biological WWTP, by understanding the fate of wastewater organic matter.

“…Dissolved organic matter (DOM) is a heterogeneous mixture of amino acids and aliphatic and aromatic hydrocarbons containing oxygen, nitrogen and sulfur functional groups, which is widespread in aquatic ecosystems (Chen et al 2003;Vazquez et al 2011;Yu et al 2013;Chakraborty et al 2014). It mainly originated from soils, residues of plants and animals, excrements of living algae and anthropogenic load of sewage, agriculture and urban landscapes (Borisover et al 2009;Herzsprung et al 2012).…”

Excitation-emission matrix fluorescence spectroscopy combined with multivariable analysis was employed to discriminate structural component of dissolved organic matter (DOM) in Xihe River, an urban river, located in western Shenyang City of China, and to reveal its correlation with water quality. Eight water samples were collected along the river across the centralized wastewater-discharge region and the dispersed wastewater-discharge region. Water quality had deeply deteriorated in the river. Based on DOM fluorescence spectroscopic properties, DOM was composed of tyrosine-like, tryptophan-like, soluble microbial by-product-like, fulvic-like and humic-like materials, among which protein-like material was dominant in the DOM fractions. The DOM in the centralized wastewater-discharge region had a lower level of aromaticity than that in the dispersed wastewaterdischarge region, and its humification degree was lower than that in the latter too. Key factors for the trophic state contained NH 4 -N, DO, DOC, TP, U 2,n and U 4,n by multivariable analysis. DOM was mainly derived from treated and untreated industrial wastewater with weak biodegradability.
