Environmental Science & Technology, Год журнала: 2021, Номер 55(8), С. 4243 - 4267

Опубликована: Март 16, 2021

With the increasing severity of global water scarcity, a myriad scientific activities is directed toward advancing brackish desalination and wastewater remediation technologies. Flow-electrode capacitive deionization (FCDI), newly developed electrochemically driven ion removal approach combining ion-exchange membranes flowable particle electrodes, has been actively explored over past seven years, by possibility energy-efficient, sustainable, fully continuous production high-quality fresh water, as well flexible management electrodes concentrate stream. Here, we provide comprehensive overview current advances this interesting technology with particular attention given to FCDI principles, designs (including cell architecture electrode separator options), operational modes approaches electrodes), characterizations modeling, environmental applications desalination, resource recovery, contaminant abatement). Furthermore, introduce definitions performance metrics that should be used so fair assessments comparisons can made between different systems separation conditions. We then highlight most pressing challenges (i.e., operation capital cost, scale-up, commercialization) in full-scale application technology. conclude state-of-the-art review considering overall outlook discussing areas requiring future.

Photothermal Membrane Distillation toward Solar Water Production

Small Methods, Год журнала: 2021, Номер 5(5)

Опубликована: Фев. 15, 2021

Abstract Freshwater production is one of the biggest global challenges today. Though desalination can provide a climate‐independent source clean water, process requires high energy consumption. Emerging advancement photothermal nanomaterials and urgent demand for green technology transition have reinvigorated established solar distillation technology. The current development vaporization focuses on material innovation interfacial heating, which largely emphasizes vapor generation efficiency, without considering pragmatic water collection. Moreover, salt accumulation another critical issue seawater solar‐driven vaporization. incorporation materials into membrane (PMD) evaporator design harmoniously resolves these issues through combination renewable efficient distillation, to achieve ultimate goal practical saline freshwater conversion. At this juncture, it imperative review recent opportunities progresses PMD system. Here, fundamental processes, strategies design, evaluation various criteria with desired properties, discussions desalination, treatment, applications are covered. Guidelines in system designs further advance that highly promising delivering portable both large‐scale decentralized systems provided.

Mechanistic Insights into the Role of Polydopamine Interlayer toward Improved Separation Performance of Polyamide Nanofiltration Membranes

Environmental Science & Technology, Год журнала: 2020, Номер 54(18), С. 11611 - 11621

Опубликована: Авг. 12, 2020

Interlayered thin-film nanocomposite membranes (TFNi) are an emerging type of with great potential to overcome the permeability-selectivity upper bound conventional composite (TFC) nanofiltration and reverse osmosis membranes. However, exact roles interlayer corresponding mechanisms leading enhanced separation performance TFNi remain poorly understood. This study reports a polydopamine (PDA)-intercalated membrane (PA-PSF2, PDA coating time 2 h) that possessed nearly order magnitude higher water permeance (14.8 ± 0.4 Lm-2 h-1 bar-1) than control TFC (PA-PFS0, 2.4 0.5 bar-1). The further showed rejection toward wide range inorganic salts small organic molecules (including antibiotics endocrine disruptors). Detailed mechanistic investigation reveals was due both direct "gutter" effect its indirect effects resulting from polyamide formation on PDA-coated substrate, playing more dominant role. provides comprehensive framework for future development
