This study explores the impact of 16 socio-demographic variables on household water demand in a tropical Nigerian community from February 2023 to January 2024, surveying eighty diverse households monthly. Descriptive and inferential statistics were applied to the survey data. Females constituted 85.8%, with 98.0% aged at least 18 and 73.6% having secondary education. Factorability of the dataset was confirmed (KMO = 63.4, <i>p</i> &lt; 0.005). Analysis identified seven key variables, explaining 72.03% of observed variance: household size, water source reliability, time cost of obtaining water, water storage strategy, consumptive water use, monthly income, and water source management type. Further scrutiny revealed two variable groups, contributing 42.3% (VAR 1 and VAR 2) and 51.4% (VAR 3, 4, 5, and 6) of total absolute variance, respectively. This analysis is vital for effective household water planning and management, especially in resource-limited regions. Extracted variables warrant attention from industry stakeholders, with subsequent investigations revealing robust relationships (55.5–99.1%) among variables. This understanding is pivotal for institutionalizing policies and strategic decision-making in household water supply planning and management. It offers comprehensive insights for aligning practices with SDG 6 goals, ensuring sustainable and equitable access to water resources.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-024-02323-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Techniques based on adsorption and extensive use of two-dimensional (2D) transition metal carbides (MXenes) with the presence of terminal functional groups have provided a high potential in the separation of organic aromatic pollutants. In this work, a 2D substrate of the MXenes family named V₂CT_x is designed to investigate the adsorption behavior of several types of dye organic pollutants using the molecular dynamics simulation technique based on Newton’s laws in the aqueous phase. Several simulation boxes are designed, which are placed in two groups, discrete simulation boxes and co-loading (Mxn-Mix) boxes. Several analyses, including root-mean-square deviation, interaction energies, radial distribution function, mean square displacement, hydrogen bond (HB) number, and the number of contacts, have been used to analyze the results. The simulation results and interaction energy show that all the dye analytes used can interact with MXene (Mxn), which indicates that MXene can be an effective adsorbent to remove pollutant molecules. Our results confirm that the adsorption process of analytes by V₂CT_x substrate is selective. The analysis of adsorption behavior shows that the loading process is spontaneous in all systems, and the values of the interaction energy for the most stable complexes are −149.95 and −104.85 kJ/mol corresponding to crystal violet and brilliants blue analytes, respectively, in both groups of discrete and Mxn-Mix simulation boxes. The strong adsorption can be attributed to the cationic nature of analytes and their nucleophilic aromatic parts, which caused strong coul interactions for the adsorption of these molecules. The HB and π–π interactions are also responsible for the adsorption of dye molecules here. The obtained results also indicate that in addition to the cationic nature, other factors, such as the linearity of the molecular structures, the charge of the dye molecules, and the molecular mass of the tested pollutants, are effective in the adsorption process. Current studies show that the Mxn nanostructure is an excellent substrate of adsorbent material that has high efficiency for the separation of organic dyes in aqueous media. It is hoped that this research can be a very good class for other target pollutants in the future.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-024-02331-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the paramount objective of this research paper is to prioritize the criticality of the factors affecting the deterioration of water pipes in Hong Kong. The framework of the developed model is envisioned based on two main modules, namely weight computation and weight aggregation. The first module incorporates identifying and categorizing water deterioration factors. Then, the relative importance priorities of water deterioration factors are scrutinized using seven weight computation methods. These methods encompass analytical hierarchy process (AHP), Monte Carlo AHP, fuzzy AHP, magnitude-based fuzzy AHP, total difference-based fuzzy AHP, spherical fuzzy AHP and Pythagorean fuzzy AHP. In this regard, fuzzy-based and Monte Carlo-based methods are leveraged to circumvent the critical shortcomings of classical AHP. The performances of weight computation methods are analyzed using statistical evaluation indicators of satisfactory index (SAT) and distance between weights (WD). The second module is a hybrid meta-heuristic-based game theory model designated for compiling the importance weights of deterioration factors obtained from the first module. In this context, a set of widely acclaimed meta-heuristics are exploited and examined for optimizing the significance of deterioration factors. Analytical results exemplified that soil-related factors implicate the deterioration process more than pipe-related, operational-related, and environmental-related factors. It was also inferred that water pressure (6.64%) is the most significant factor influencing water pipe deterioration followed by internal corrosion and protection method (6.11%), and then soil corrosivity (6.05%). On the other hand, length (1.93%), rain deficit (1.97%), and street block length (2.33%) constitute the least influencers on water pipe deterioration. Results also demonstrated that spherical FAHP outperformed other variants of AHP accomplishing SAT and WD of 0.065 and 0.057, respectively. Comparative analysis revealed that particle swarm optimization-based game theory is a better mechanism than the remainder of meta-heuristic-based game theory models in obtaining a more accurate compromised-based weighting vector to the experts’ judgments. It is envisaged that this research can assist the water supplies department in identifying, assessing, and prioritizing the impairment causes of water pipelines in Hong Kong. It can also aid in establishing more accurate deterioration models and more cost-effective maintenance intervention programs.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"14 12","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-024-02274-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142712507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
