The system demonstrates superior separation performance under high-salinity conditions, achieving a remarkable salt crystallization rate of 72 g m<sup>−2</sup> h<sup>−1</sup> in 20 wt% saline solution with a separation factor of 2.72 at a NaCl/Na₂SO₄ ratio of 3. The system maintained high-efficiency and stable operation during prolonged cycling experiments. By synergistically combining salt separation/collection with interfacial evaporation on a unified platform, this study presents an efficient and sustainable approach for salt fractionation that significantly advances the field of brine resource recovery.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"75 ","pages":"Article 107877"},"PeriodicalIF":6.3,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144069742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
