Three hundred and twenty-four fish (weighed = 60 ± 2.35 g initially) were divided into nine equal groups, each with three replicates for a duration of 60 days. These experimental groups were represented as follows: (S0/NS) salinity-free group fed with basal diet, (S6/NS) 6.00 ppt salinity stress group fed with basal diet, (S12/NS) 12.00 ppt salinity stress group fed with basal diet, (S0/MSP1) salinity-free group fed with 1% MSP, (S6/MSP1) 6.00 ppt salinity stress group fed with 1% MSP, (S12/MSP1) 12.00 ppt salinity stress group fed with 1% MSP, (S0/MSP2) salinity-free group fed with 2% MSP, (S6/MSP2) 6.00 ppt salinity stress group fed with 2% MSP, and (S12/MSP2) 12.00 ppt salinity stress group fed with 2% MSP.

All three methods delineated approximately 95% of the groundwater basin as being moderately to highly susceptible to contamination, which was mainly due to the sandy soil, high recharge rate, gentle topography, and agricultural activities related to land use. A positive linear correlation was also found, during the validation of the final vulnerability maps, between the vulnerability indices and observed nitrate concentration. The vulnerability indices of SI, DRASTIC, and GOD showed correlations of 0.5635, 0.3615, and 0.3499, respectively, with the available nitrate concentration in the groundwater. Thus, SI was concluded as the most suitable method for assessing the vulnerability of shallow aquifers in southeast Hungary to contamination.

Usually, hydrophobic microfiltration membranes are employed in MD process; however, conventional MD membranes possess rather low permeating flux and are prone to fouling. As a result, MD has not been widely adopted for water treatment and separation purposes at large commercial scale yet. Hence, development of novel MD membranes with enhanced properties is an important task. One of the main approaches to adjust porous structure and properties of MD membranes is through incorporation of different additives in membrane matrix. For the first time, the present paper overviews the use of porous organic and inorganic materials with controlled pore size such as metal organic frameworks, covalent organic frameworks, halloysites, zeolites and carbon nanotubes for enhancing properties and separation performance of MD membranes. While the employing of some of these materials in MD membranes looks promising, there are some issues that need to be addressed such as fabrication costs of such porous materials, stability of the additive’s incorporation in the membrane matrix and lack of long-term testing of the prepared MD membranes with real feed streams.

This study investigates the influence of the fogging technique on improving the process of HDH water desalination integrated with a cooling system. An experimental study investigated how operational factors like the mass flow rate ratio, feed water temperature, feed water salinity, cooling water temperature, and nozzle orifice diameter affected the salinity of the produced water, freshwater productivity, and GOR. The fogging system achieves maximum productivity of 25.08 L/h and 25.39 L/h when employing nozzles with orifice sizes of 0.3 mm for feed water salinity levels of 34,000 ppm and 12,000 ppm, respectively. The greatest GOR was achieved by utilizing a nozzle orifice of 0.3 mm, resulting in GOR values of 8.79 and 8.84 for concentrations of 34,000 ppm and 12,000 ppm, respectively. The salinity of the produced water reaches 1500 ppm and 500 ppm when the fog is created at a temperature of 80 °C, with feed water salinity levels of 34,000 ppm and 12,000 ppm, respectively. The fogging nozzle’s size directly affects the generated water’s salinity. When the size of the fogging nozzle reduces from 0.3 to 0.1 mm, the salinity decreases by about 34.8% and 33.3% for 34,000 ppm and 12,000 ppm, respectively. This pattern indicates that the water’s salinity decreases as the nozzle’s diameter decreases. Nevertheless, under identical circumstances, water productivity declined by 56% and 55% at 34,000 ppm and 12,000 ppm, respectively. The water production cost was 0.0268–0.0088 ($/liter). The study concludes that the salinity of the generated water reduces as the feed water temperature increases and the nozzle size decreases. In contrast, water productivity, GOR, and lower cost are enhanced using a larger nozzle.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 6","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02446-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896625","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}

Summer irrigation with the greywater and tap water sources was simulated (370 mm) followed by winter rainfall simulation (370 mm). Soil chemical, physical and microbial properties were determined after each simulation. Irrigation with SH and LLD greywaters was least harmful to soil chemistry; however, LLD decreased soil infiltration rate by 48–53%, and SH resulted in hydrophobic crusting. Irrigation with PLD and DW greywater was most damaging, resulting in alkalisation, sodification and salinisation accompanied by soil structural degradation, decreasing infiltration by 85–100%. All treatments reduced soil bacterial diversity and species richness. Rain simulation was only able to reduce sodicity and salinity associated with PLD and DW application on the rhodic soil, as the clay fraction was more stable, permitting some infiltration. Therefore, PLD and DW greywaters should not be used directly for irrigation, especially on bleached soils, as this can halt rainwater percolation. Furthermore, use of less chemically harmful SH or LLD liquid greywaters could result in undesirable soil physical problems in the long term.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 5","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02460-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883757","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}

The main objectives were to calculate various water quality indices for drinking and irrigation purposes, to develop an automated system using convolutional neural networks (CNN) to predict these indices and to increase the transparency of these models using explainable artificial intelligence (XAI) methods. Methodologically, the study used CNN algorithms optimised by Bayesian techniques for the prediction of eight water quality indices, coupled with SHAPley Additive exPlanations (SHAP) analysis under XAI to interpret the complex decision-making processes of these models. This dual approach enabled a comprehensive and insightful assessment of water quality. Using a robust dataset from the Aseer region, eight water quality indices were calculated, revealing significant variations and highlighting areas of concern. In this study, the entropy weight-based DWQI averaged 77.90 with a high standard deviation (std) of 39.08, reflecting considerable variability. The automated CNN models demonstrated robust performance in predicting water quality indices, with high accuracy (R² = 0.959 in training and 0.945 in testing) for sodium percentage (Na%). However, the Magnesium Hazard (MH) index showed lower accuracy, suggesting possible overfitting and the need for further optimisation. SHAP analysis highlighted chloride, sulphate, and total dissolved solids as key contributors to the WQI, while sodium and calcium were significant for the sodium adsorption ratio.

The receiver operating characteristic curve analysis yielded an area under the curve of 0.835, indicating high model reliability. The approach incorporates easily accessible data, including NASA LaRC POWER, the digital elevation model, Landsat imagery, and total dissolved solids, offering a replicable and adaptable framework, particularly useful in regions with limited hydrogeological data.
