Nanofiltration (NF) membranes have been widely applied in many important environmental applications, including water softening, surface/groundwater purification, wastewater treatment, and reuse. In recent years, a new class of piperazine (PIP)-based NF featuring crumpled polyamide layer has received considerable attention because their great potential for achieving dramatic improvements membrane separation performance. Since the report novel Turing structures that exhibited an order magnitude enhancement permeance ( Science 2018, 360 (6388), 518−521), number published research papers on this emerging topic grown exponentially to approximately 200. critical review, we provide systematic framework classify morphologies. The fundamental mechanisms fabrication methods involved formation these morphologies are summarized. We then discuss transport solutes how phenomena could simultaneously improve permeance, selectivity, antifouling applications highlighted, future opportunities/needs identified. insights review guidance further development high-performance tailored wide range applications.

Does Surface Roughness Necessarily Increase the Fouling Propensity of Polyamide Reverse Osmosis Membranes by Humic Acid?

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(6), P. 2548 - 2556

Published: Jan. 31, 2023

Surface roughness has crucial influence on the fouling propensity of thin film composite (TFC) polyamide reverse osmosis (RO) membranes. A common wisdom is that rougher membranes tend to experience more severe fouling. In this study, we compared behaviors a smooth membrane (RO-s) and nanovoid-containing rough (RO-r). Contrary traditional belief, observed for RO-s, which can be ascribed its uneven flux distribution caused by "funnel effect". Additional tracer filtration tests using gold nanoparticles revealed patchlike particle deposition pattern, confirming adverse impact effect" water transport. contrast, experimentally lower explained by: (1) weakened thanks presence nanovoids, regulate transport pathway through (2) decreased average localized over surface due increased effective area nanovoid-induced features. The current study provides fundamental insights into critical role in fouling, may have important implications future development high-performance antifouling

Inhibiting Polyamide Intrusion of Thin Film Composite Membranes: Strategies and Environmental Implications

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(29), P. 10860 - 10869

Published: July 10, 2023

Thin film composite polyamide (TFC) nanofiltration (NF) membranes represent extensive applications at the water-energy-environment nexus, which motivates unremitting efforts to explore with higher performance. Intrusion of into substrate pores greatly restricts overall membrane permeance because excessive hydraulic resistance, while effective inhibition intrusion remains technically challenging. Herein, we propose a synergetic regulation strategy pore size and surface chemical composition optimize selective layer structure, achieving for separation performance enhancement. Although reducing prevented intrapore, was adversely affected due exacerbated "funnel effect". Optimizing structure via modification substrate, where reactive amino sites were in situ introduced by ammonolysis polyethersulfone allowed maximum without size. The optimal exhibited excellent water permeance, ion selectivity, emerging contaminants removal capability. accurate optimization is anticipated provide new avenue state-of-the-art fabrication, opens opportunities promoting more efficient membrane-based treatment applications.
