Supercritical water desalination can concentrate and extract minerals from these brines, but the effects of mixed salt interactions, organic degradation with additives, and the technology's economics are not well understood at supercritical condition. The present study evaluated and experimentally studied an integrated supercritical water desalination and oxidation (SCWDO) process for treating real-produced water samples from oil/natural gas field. The complex interactions between the various anions and cations in produced water were extensively evaluated. Most of the divalent and trivalent ions were extracted below 250 °C while the majority of the monovalent salt were removed between 380 to 410 °C. The treated real produced water was of drinking water quality, with &lt;500 mg/l of total dissolved solid (TDS) and with 100 % organics removal. The heat liberated during the organic oxidation could be utilized internally and for electricity generation for enhanced the energy efficiency and lower cost of produced water treatment. With system optimization, the proposed SCWDO process can essentially be made a net zero energy process. A novel process flow diagram for the commercial scale self-powered hybrid SCWDO technology was proposed as a cost-effective produced water treatment to mitigate the environmental crises. Techno-economic analysis showed that produced water treatment cost with SCWDO can be reduced to 2–3 $/m³ and can be up to 60 % cheaper to traditional deep well reinjection. Additionally, the proposed SCWDO process could achieve net negative CO₂ emission.</div></div>","PeriodicalId":299,"journal":{"name":"Desalination","volume":"613 ","pages":"Article 118963"},"PeriodicalIF":8.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922049","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}

This has exposed critical limitations in traditional extraction processes such as solar evaporation and hard rock mining. These methods usually suffer from long processing times, low lithium selectivity, extensive land use, and are environmentally disruptive. As a result, there is a growing need for cleaner, more selective alternatives. Recovery from different sources such as salt lake brines, seawater, geothermal brines, and battery recycling streams has brought the exploration and development of novel recovery technologies. Electrochemical techniques are usually more compact and present a lower by-product waste disposal burden than conventional methods, including hard rock mining, solar evaporation, etc. This in turn, helps in minimizing the landscape disruption and lowering the ecological footprint of lithium extraction operations. Another important advantage of electrochemical methods is that they do not usually employ chemicals that would result in soil and groundwater pollution; thus, they are much cleaner processes. In this work, the recent advances in the electrochemical recovery of valuable metals are summarized with special emphasis on lithium recovery from various sources using processes such as capacitive deionization (CDI) and electrodialysis (ED), all carrying efficiency and selectivity, with less impact on the environment. Furthermore, this review aims to offer a basic understanding of electrochemical processes and compile their contributions toward environmental impact reduction while highlighting their viability alongside green extraction paradigms that tackle, in context, the reduction of the dependence on traditional high-impact mining processes. Additionally, hybrid electrochemical processes such as coupling CDI with a fractional submerged membrane distillation crystallizer (F-SMDC), and the integration of F-SMDC with electrocrystallization are suggested to improve the lithium extraction performance of electrochemical methods.</div></div>","PeriodicalId":299,"journal":{"name":"Desalination","volume":"612 ","pages":"Article 118960"},"PeriodicalIF":8.3,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887558","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}

The creation of crumpled surface morphologies is believed to significantly enhance membrane permeability due to increased surface areas and optimized transport pathways. However, there is still a lack of facile and reliable techniques for fabricating crumpled TFC-PA membranes for ultra-permeable nanofiltration. In this study, we introduce a novel scaffold-templating approach for creating highly crumpled TFC-PA membranes via interfacial polymerization (IP). A pre-decorated macroporous nylon scaffold was adopted as a template for IP, where the water-oil interface was confined within the surface cavities of the scaffold using vacuum filtration. This templating strategy enables the formation of a crumpled, loosely crosslinked PA layer that replicates the geometry of the scaffold, thereby greatly facilitating water transport. As a result, the developed membrane shows an ultrahigh pure water permeance of 54.3 L m⁻² h⁻¹ bar⁻¹ and a satisfactory Na₂SO₄ rejection of 97.4%, alongside excellent mono-/divalent anion (SO₄²⁻/Cl⁻) selectivity of up to 50 under a low applied pressure of 2 bar.
