The results of scanning electron microscopy, TGA-DSC, Fourier infrared spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy characterization showed that the PTFS was not a simple mixture of raw materials and a chemical reaction occurred, thereby generating new chemically connected bonds. The optimum removal of PS could reach 92.5% at the dosage of 0.6 mg/L, initial concentration of 70 mg/L, pH of 7, stirring intensity of 350 rpm, settling time of 60 min, and kaolin concentration of 70 mg/L. The best removal rate of TiO<sub>2</sub> could reach 95.3% when the dosage was 0.8 mg/L, the initial concentration was 70 mg/L, the pH was 7, the stirring intensity was 350 rpm, the settling time was 60 min, and the kaolin concentration was 50 mg/L. The flocs produced by PTFS were large and dense. In the early stage of coagulation, the flocculation mechanism was dominated by electroneutralization, and in the middle and late stages of coagulation, adsorption, bridging, and netting were dominated.

In this study, multivariate statistical analysis and spatial distribution based on geographic information system (GIS) was used to examine the status of pollution and health risk, irrigation water quality, and stochastic geo-environmental risk sources of 16 potentially toxic elements (PTEs: Na, Mg, K, Ca, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Hg, and Pb) concentrations from samples in the dam. Also, spatial analyzing of quality indices was used to assess the dam's feasibility for irrigation and drinking. As per the results of the study, the dam water has mild heavy metal (loid) pollution, which is measured at 16 PTE by the heavy metal (loid) pollution index (HPI) and heavy metal (loid) evaluation index (HEI) values. The pollution level is low during the rainy season and moderate during the dry season. The water at sampling station S3 (HPI = 146.50) is unfit for consumption and cannot be used for drinking. The majority of harmful metal species exhibited elevated concentrations (notably Pb: 51.78 μg/L, Cr: 8.55 μg/L) in the dam lake water, particularly during the dry season. The toxic metals Pb and Cd account for 15.95% of the total variance, with a high degree of loading.

A 2020 pilot study showed that a 5% raw water bypass and target caustic alkalinity range of 26-36 mg/L as CaCO<sub>3</sub> resulted in 25% and 7% carbon dioxide and lime savings, respectively. Considering this promising outcome, the potential for scaling and corrosion within the plant was evaluated during a subsequent split treatment trial in this study. Mild steel scale coupons were assessed for scaling and corrosion at four different treatment conditions. These results found that a 5% raw water bypass is predicted to have a minimal impact of scaling and corrosion on the water plant infrastructure when compared to full lime softening. Results are significant since split treatment can save over $150,000 annually with no apparent change in water quality, improving the plant's resilience and sustainability.

Relocation of SHMP did not show appreciable sequestration of hardness ions. Adjusting dosage and/or using a polyphosphate blend is recommended.

Therefore, there is a need to develop technologies aiming at removing CIP from sludge. In this study, electrically activated peroxymonosulfate (E/PMS) was investigated to remove CIP from WAS. The optimal conditions for the degradation of CIP in sludge by E/PMS were determined by response surface methodology (RSM) simulations combined with experimental validation. The highest CIP removal level of 93.8% was achieved in 10 min at a dosage of 250 mg/g dry solid (DS) PMS, and an electrolysis voltage of 23 V.

This research aims to assess the impact of various environmental parameters on Cirebon's estuaries, focusing on physical components (such as temperature, total solids [TS], and turbidity), chemical components (including pH, biochemical oxygen demand (BOD), dissolved oxygen (DO), nitrate, and phosphate), and microbiology components (specifically total coliforms). These comprehensive components have notably impacted environmental parameters during pre-, during, and post-COVID-19 pandemic based on the Water Quality Index (WQI) assessment in Cirebon's estuaries. In the port city of Cirebon, located on Java Island's northern coast, the water quality of three river estuaries Kesenden, Sukalila, and Kalijaga was analyzed before and after the CARE implementation. Water samples collected in 2019, 2020, 2022, and 2023 were evaluated against Class II water quality standards per Indonesian Government Regulation No. 22 of 2021. The assessment of WQI was determined using the National Sanitation Foundation Water Quality Index (NSF-WQI) technique revealing significant fluctuations and trends across various stations over the 2019-2023. In 2019, the water quality at Kesenden, Sukalila, and Kalijaga stations was recorded at 52.21, 56.40, and 53.36, respectively. By 2020, began of COVID 19, there was a noticeable decreasing of WQI, Sukalila sustained a \"Moderate\" classification with a WQI of 54.59, whereas Kesenden and Kalijaga witnessed declines with values recorded at 49.5 and 49.7, respectively. However, the peak-implementation of the CARE program in 2022 saw a drastic decline in water quality, with values dropping below the threshold in all observed stations, 23.97 in Kesenden, 23.10 in Sukalila, and 35.36 in Kalijaga. Meanwhile, the water quality in 2023 experienced increasing (remained in the poor category) with index values of 44.31, 35.14, and 42.0 at Kesenden, Sukalila, and Kalijaga, respectively. The findings underscore the complex interplay between human activities and environmental health, highlighting the need for sustainable practices and robust water management policies to mitigate the adverse effects of such disruptions. The results from the monitoring of ocean health pre- and post-the CARE implementation in the pandemic era have provided a unique opportunity to reflect on human behavior and its impact on the environment, emphasizing the importance of adopting pro-environmental behaviors to support sustainable development in the post-pandemic era.

The well numbers are 5118 (Cengziköy), 236 (Yesilyurt), 5147 (Döganci), 4548 (Döganci), 2320 (Gunesköy), 881(Guzelyurt), 615 (Aydinköy), 287 (Kalkanli), 2400 (Guzelyurt), and 834 (Guzelyurt). The results obtained from the analysis were compared with the result of groundwater quality data that were taken from these wells in the past 10 years to ascertain the level of contamination of the wells caused by seawater intrusion in the Guzelyurt coastal aquifer. Nine of the wells are affected by seawater intrusion, while one is not affected. Well, 5118 (Cengzıköy), is not affected by the salinity problem. Within the past 11 years, the salinity in wells 615 (Aydinköy) and 834 (Guzelyurt) increased, while wells 881 (Guzelyurt), 287 (Kalkanlı), 2320 (Guneskoy), 236 (Yeşilyurt), 5147 (Dogancı), 4545 (Dogancı), and 2400 (Guzelyurt) show a low salinity. Controlling seawater intrusion and conserving groundwater resources is critical. In conclusion, the study recommends continuous monitoring of the Guzelyurt aquifer, the adoption of desalination plants, and the use of treated wastewater effluent as an option to reduce groundwater withdrawal. PRACTITIONER POINTS: Controlling seawater intrusion and conserving groundwater resources is critical. Groundwater established the significance of the water circle, and it is found in aquifers. The use of polluted groundwater can cause health problems.</p>","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 2","pages":"e70010"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143068350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
