The results showed that the relationship between water consumption and socioeconomic development varied depending on different industrial divisions. The IWCI, established based on water consumption data was highly sensitive to changes in socioeconomic development, especially rapid changes. Compared to the raw water consumption data, the IWCI presented a better performance in evaluation indicators for the selected several divisions, with a Pearson correlation coefficient ranging from 0.70 to 0.85 and a normalized mutual information ranging from 0.31 to 0.45. Overall, the IWCI provides an effective way to evaluate socioeconomic development trends by relying solely on water consumption data, particularly for industrial divisions where water plays an important role in production. The index allows managers to quickly assess and analyze socioeconomic development trends and develop corresponding response measures.</div></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":null,"pages":null},"PeriodicalIF":4.5,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142357960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oil spills to free waters is one of the most important threats to living beings. It has been believed that using sorbents is the most effective method for this purpose. In this research, usage of tire rubber with improved hydrophobic properties is considered. For this purpose, carbon black nanoparticles (CBNs) were surface modified with vinyltrimthoxysilane (VTMS) at concentrations of 1, 5 and 10 by sol-gel method. Before, the CBNs were hydroxylated to increase silane grafting content. The surface modified was evaluated using XPS, FTIR, TGA, BET and FESEM analysis. Results showed a great change in the CBNs nature from hydrophilic to hydrophobic after silane modification that could help in more oil absorption and water repletion at the same time. In fact, the water contact angle (WCA) of the CBNs changed from 40 to 135°. The pure and silane grafted CBNs were added to the tire tread compound to prepare elastomeric nanocomposites as oil sorbent. The results showed that the modified nanocomposite had a higher reinforcement index than the samples contained pure and hydroxylated CBNs. The effects of CBNs on WCA, OCA and oil absorption capacity of the samples were also determined. It was found that silane modification a considerable increase in the WCA from 61.2° to 125.03° and a decrease in the oil contact angle (OCA) from 70.01° to 17.74°.

Systematic assessment of groundwater and leachate contamination may be useful in selecting the appropriate method of leachate management or treatment processes. The use of indicators to quantify the contamination potential of leachate and groundwater in the vicinity of MSW could help landfill managers assess their quality. Therefore, the aim of the study was to assess the representativeness of selected indicator methods for analyzing the temporal variability of leachate and groundwater properties in the vicinity of two municipal waste landfills in a Central European country (Poland). The leachate pollution index (LPI), sub-LPI and adjusted leachate pollution index (r-LPI) were used to assess the quality of leachate water, while the landfill water pollution index (LWPI) was used to assess the variability of groundwater quality. The results confirmed that LWPI is an effective method for assessing the quality of groundwater in the vicinity of municipal waste landfills. The obtained results confirm the negative impact of landfills, despite the insulation used. LWPI showed poor quality of groundwater and visible impact of the landfill (landfill W, average LWPI - 2.34) and moderately polluted waters and minor impact of the landfill (landfill S, average LWPI - 1.37). In most cases, it was observed that two parameters, EC and TOC, are the main factors contributing to the deterioration of groundwater quality. The sub-LPI analysis showed that leachates from both landfills have a very low content of heavy metals, so they should not have a negative impact on the biological treatment process. The obtained r-LPI values were in all cases higher than the calculated LPI values. For landfill S, the average r-LPI was 26.3 (Z-1) and 25.7 (Z-2). However, the average LPI was 13.5 (Z-1) and 13.2 (Z-2). For landfill W, the average r-LPI was 14.6 and the average LPI was 11.4. Analysis conducted on multi-year leachate and groundwater data using specific indicators can help managers better understand the impact of MSW on surrounding areas and help avoid potential operational problems in the future.</p></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":null,"pages":null},"PeriodicalIF":4.5,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212371724000271/pdfft?md5=c4dfa5aa40e6fd10f6101d9030f68f20&pid=1-s2.0-S2212371724000271-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142129358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rain energy was not used as an energy source up to now; so, in this research its applicability was investigated as a green large scale power source.

Firstly, the kinetic energy of rain drops was converted to electricity using piezoelectric harvesters designed and named as Pizo-panel collectors. Secondly, potential energy of collected rainwater was enhanced by utilizing designed towers and converted to electricity using a water turbine. Thirdly, collected water was used in osmotic power units to generate electricity from the salinity gradient of that rain water and brine. The results show that generated power in the presented power plant named as rain power plant, was considerable and can be used for diversifying of energy basket. In addition to power generation, collected water in the rain power plant can be used for supplying urban and agricultural need for water.

This research aimed to optimize and address the environmental challenges of MED-TVC desalination plants in areas with insufficient sunlight, unstable weather conditions, and limited economic resources. To this end, a model of an electric heater for generating thermal energy coupled with an optimized MED-TVC desalination plant was proposed.

The structure and surface of STEA were characterized by elemental C, H, N, and Cl analysis, X-ray diffraction, infrared spectroscopy, ¹³C solid-state nuclear magnetic resonance spectroscopy, thermogravimetric analysis, specific surface area and pore size distribution determination, and point of zero charge measurement.
