This research purposed to establish the relationship between absorbance differential spectra and trihalomethanes-4 (THM4) formation potential, as well as the estimated cytotoxicity of tropical peat water DOM percentage. The ion exchange resin was used to separate the DOM components from peat water. In addition, the UV–Vis spectrum was examined between 200 and 700 nm. The hydrophobic-acid (HPOA) fraction contains the highest concentration of dissolved organic carbon (DOC), THM4 production potential, and calculated cytotoxicity. On the other hand, the hydrophilic-neutral (HPIN) fraction has the lowest potential THM4 production. The UV–Vis absorbance spectra of all DOM fractions showed a comparable peak at 277 nm. The differential spectra of 277 nm (ΔA<sub>277</sub>) indicated a significant association with DOC concentration (99.6 %), trichloromethane (TCM) creation (86.6 %), total-THM4 (TTHM4) (81.3 %) formation, THM4 estimated cytotoxicity (89.7 %), and a moderate correlation with bromodichloromethane (BDCM) formation (55.6 %). Meanwhile, ΔA<sub>277</sub> had a poor correlation with brominated THM4 formation potential (chlorodibromomethane (CDBM): 2.59, tribromomethane (TBM): 2.78 %). The absorbance differential spectra might be employed as a surrogate measure for the peat water DOM fraction and its precursor properties to form THM4 during the chlorination process, as well as its estimated cytotoxicity.</p></div>","PeriodicalId":34143,"journal":{"name":"Water Cycle","volume":"4 ","pages":"Pages 207-215"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666445323000259/pdfft?md5=1eb013aab416040237b0e863b64d1f95&pid=1-s2.0-S2666445323000259-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135211221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrocoagulation (EC) is one such technology that is broad-based, highly reliable, and cost-effective. It also has a high pollutant removal efficiency and generates less sludge when compared with other techniques. However, despite being effectively used to treat a wide range of wastewater, a thorough examination of its efficiency under various process variables has not been critically examined. Various operating factors, such as pH, current density, the conductivity of the solution, electrode material, and mixing conditions, impact the electrocoagulation system. This paper aims to provide a comprehensive overview of the electrocoagulation technique and examine the current challenges to the efficiency of the technique due to the various operating conditions.

In order to investigate the variation of water quality along the pipeline and flow direction in a typical urban landscape river replenished with reclaimed water, relevant water quality indexes were consecutively monitored for 8 months. Concentrations of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) all showed a downward trend along the flow direction in reclaimed water effluent pipeline. However, values of turbidity, COD, and chlorophyll <em>a</em> (Chla) were decreased significantly, while concentrations of TN and TP were increased in the mixed area of reclaimed water and river. Furthermore, along Licun River, an upward trend of COD and ammonia-nitrogen (NH<sub>4</sub><sup>+</sup>-N) was observed in summer, while in other seasons, a falling first and then rising trend of COD concentration appeared. The concentration of NH<sub>4</sub><sup>+</sup>-N randomly fluctuated between 0.08 mg/L to 2.05 mg/L among all seasons, and TN and nitrate-nitrogen (NO<sub>3</sub><sup>−</sup>-N) were below 15 mg/L with a downward first and then upward trend in each season. The concentration of TP showed a slightly upward trend (ranging from 0.08 mg/L to 0.57 mg/L) and Chla was at a relatively low level (0 – 46.32 μg/L). The correlation analysis revealed that light intensity, nitrogen and phosphorus were the influential factors of algae growth in river. In addition, the biomass of emergent plants and submerged plants was increased after replenishing with reclaimed water, playing a vital role in the remediation of urban landscape river.</p></div>","PeriodicalId":34143,"journal":{"name":"Water Cycle","volume":"4 ","pages":"Pages 137-144"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46226497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the water contains hydrophobic high molecular weight natural organic matter (NOM) in form of humic and fulvic acids. These acid contaminants caused brownish color and acidic pH of the water. The performance of treatment processes such as filtration, adsorption, and ozonation also reduced the presence of NOM, while several chemical and physical parameters were discussed. Although reports regarding PWT were available, most of them only focused on the removal of standard physicochemical parameters such as color and pH. This was because there is still limited information on the removal of other parameters such as disinfection by-products (DBPs), organic matter fraction, and other emerging contaminants.

Excessive releases of CR have resulted in adverse impacts on water environments and ecological systems due to its non-biodegradable, toxic and carcinogenic properties. Therefore, the removal of CR from water environments is of important for wastewater treatment. Previous studies have proved that metal-organic frameworks (MOFs) were feasible for CR adsorption, but less stable in water environments. Several functionalized materials have therefore been used to produce MOF-derived composite material for better performance. To simplify the synthesis processes and reduce the energy consumption, an ionic liquid (IL) was used in this study for the synthesis of [BMIM][PF<sub>6</sub>]/ZIF-8 (BP/Z) composite material. The morphological structure of this material remained stable after the incorporation of IL. The equilibrium time of CR adsorption was 90 min with a maximum adsorption capacity of 1463 mg/g.
