Although high-pressure operation combined with antiscalants is typically employed to improve the techno-economic feasibility of NF, it frequently results in increased energy and chemical consumption. In this study, an antiscalant-free approach, ultralow-pressure NF, was applied to regulate the crystallization process and maintain a stable flux. The gypsum scaling behavior under different pressures as well as the applicability of ultralow-pressure NF were investigated. The results revealed that the normalized flux remained above 0.95 at low pressure but declined rapidly at high pressure. Minimal mineral deposition and a loosely structured scaling layer were observed at low pressure, whereas high pressure led to extensive crystal formation, covering the membrane surface and blocking pores seriously. These differences in scaling behavior were attributed to the variations in the induction period under different pressures. Numeric simulation results demonstrated that system pressure regulated the induction period by affecting concentration polarization and altering the migration trajectories of gypsum crystals and precursors. A simple flushing process was found to effectively reset the induction period, thereby impeding gypsum scaling. As lowering the pressure significantly prolonged the induction period before flux decay, the flushing intervals could be extended. An economic assessment confirmed the feasibility of ultralow-pressure NF. This study proposes an energy-efficient and antiscalant-free strategy for achieving sustainable separation in the context of low-carbon water treatment.</div></div>","PeriodicalId":299,"journal":{"name":"Desalination","volume":"602 ","pages":"Article 118633"},"PeriodicalIF":8.3,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite abundant cesium resources in Qinghai-Tibet Plateau salt lakes, concentrations remain low, and existing adsorbents generally exhibit limited adsorption capacities. Consequently, there is a pressing need for the development of an adsorbent capable of effectively separating and efficiently extracting cesium ions. This work utilizes the unique functional groups and negative charge characteristics of the two-dimensional (2D) MXene surface to promote the precipitation and crystallization of 2D layered double hydroxides (LDH), thereby enabling the in-situ growth of hydrotalcite on the MXene surface and synthesizing a 2D/2D stacked Na⁺-MXene/LDH composite. The results indicated that Na⁺-MXene/LDH exhibited enhanced specific surface area and interlayer spacing, introducing additional active sites that significantly improved Cs⁺ adsorption capacity, with a maximum recorded uptake of 961.5 mg/g, surpassing previously reported MXene-based adsorbents. Adsorption tests conducted on brines from four hydrochemical types of salt lakes on the Qinghai-Tibet Plateau revealed that Na⁺-MXene/LDH displayed the highest distribution coefficient (K_d^Cs) of 31.92 × 10⁴ mL/g in Dong Taijnar Lake, demonstrating a strong affinity and selectivity for Cs⁺. The mechanisms underlying the enhanced adsorption performance were elucidated. Additionally, ecological safety assessments, along with evaluations of microbial diversity and water quality in Qinghai Lake, confirmed that Na⁺-MXene/LDH preserved microbial diversity and stabilized community structures, thereby underscoring its non-toxic and environmentally friendly characteristics.

In addition to the macroscopic light trap effect, the salt accumulation deposited on the outer wall of the previously fabricated 3D-cup shaped device appears to be a salt layer that loosely adheres to the wall of the device, which is beneficial for recovering the steam generation performance of the evaporator by easily scraping out the layer of salt accumulation via the steel rule. The salt accumulation trend of the previously fabricated 3D cup-shaped evaporator is presumably driven by the siphoning effect and capillarity, which is also confirmed by adjusting the water head to 1.5 and − 1.5 cm. The evaporative interface for the 1.5 cm group lacks a siphoning effect, and its water supply is insufficient for evaporation. For this reason, the evaporative interface for the 1.5 cm group was rapidly dried and discontinued to work until the 40th hour. Nevertheless, the siphoning effect can not only supply adequate brine water to the evaporative interface but also form a salt layer on the outer surface of the device at the 7th hour for the −1.5 cm group. As time progresses, the salt layer becomes thicker and loosely adheres to the surface, which can be easily scraped out by a blade.
