In this study, two feeding patterns (pulse feeding: 8 ​L/4 ​h and semi-continuous feeding: 8 ​L/23 ​h) were evaluated for their effects on MV anaerobic digestion from multiple perspectives in a laboratory-scale reactor. The results demonstrated that semi-continuous feeding not only achieved a higher soluble chemical oxygen demand (sCOD) removal rate of 78.48% but also increased the production of biogas and methane by 20.04% and 51.48%, respectively. In addition, the chemical composition analysis suggested that the semi-continuous feeding pattern degraded the majority of lignin/CRAM and aromatic substances more effectively than the pulse feeding pattern. Moreover, the microbial analysis revealed that semi-continuous feeding increased the number of dominant bacteria, including Chloroflexi, Synergistetes, and Cloacimonetea, and methanogenic archaea, including <em>Methanosaeta</em> and <em>Methanosarcina</em>.

The unconfined coastal aquifer of Ghiss-Nekor, located in a semi-arid area, is particularly vulnerable to seawater intrusion (SWI) because of excessive groundwater pumping and climate change impacts. Therefore, the main goal of the present work is to track the spatiotemporal evolution of SWI in the Ghiss-Nekor aquifer by analyzing data from the years 2015 and 2022 using appropriate geochemical approaches. Accordingly, a range of geochemical techniques were employed, including the Piper diagram, Chadha's diagram, Gibbs diagram, Stiff diagram, major ions variation maps, Hydrochemical Facies Evolution Diagrams (HFE-D), and seawater fraction (f_sea). As a result, Gibbs diagram clearly indicates the contribution of seawater to the salinization of the Ghiss-Nekor aquifer. Further information is provided by the Piper, Chadha, and Stiff diagrams, which reveal that 29%–38% of the wells studied display Na–Cl water type, a characteristic feature of seawater facies. Additionally, statistical analysis shows a significant increase in salinity levels between 2015 and 2022. Furthermore, the spatiotemporal analysis using the differential mapping technique (DMT) confirmed the increase of salinity, particularly near the shoreline. Additionally, the HFE-D showed that the region impacted by SWI increased from 14% to 20% between 2015 and 2022, and the maximum f_sea value rose from 14.84% to 25.77% over the same time frame. Our findings reinforce the assumption that SWI is worsening over time in the Ghiss-Nekor aquifer. In summary, the techniques used in this study were effective in tracking the spatiotemporal evolution of SWI in the aquifer and in quantifying it. The results of this study can inform the development of effective strategies for managing SWI in coastal aquifers.</p></div>","PeriodicalId":34143,"journal":{"name":"Water Cycle","volume":"4 ","pages":"Pages 104-119"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49160832","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}

When the NaCl concentration was 50 ​g/L, the removal rate of NO₃⁻-N decreased to 80.59% at first, and the removal rate of NO₃⁻-N recovered to 98% after 16 days of operation. When the NaCl concentration increased to 80 ​g/L, the NO₃⁻-N removal rate decreased to 50%, and the reactor still could not recover its performance after long-term operation.

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 (ΔA₂₇₇) 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 %).
