Nanofoamed Polyamide Membranes: Mechanisms, Developments, and Environmental Implications

Environmental Science & Technology, Год журнала: 2024, Номер 58(47), С. 20812 - 20829

Thin film composite (TFC) polyamide membranes have been widely applied for environmental applications, such as desalination and water reuse. The separation performance of TFC strongly depends on their nanovoid-containing roughness morphology. These nanovoids not only influence the effective filtration area but also regulate transport pathways through film. Although there ongoing debates formation mechanisms nanovoids, a nanofoaming theory─stipulating shaping morphology by nanobubbles degassed CO

Removal of Heavy Metals from Wastewaters and Other Aqueous Streams by Pressure-Driven Membrane Technologies: An Outlook on Reverse Osmosis, Nanofiltration, Ultrafiltration and Microfiltration Potential from a Bibliometric Analysis

Membranes, Год журнала: 2024, Номер 14(8), С. 180 - 180

Опубликована: Авг. 22, 2024

A bibliometric study to analyze the scientific documents released until 2024 in database Scopus related use of pressure-driven membrane technologies (microfiltration, ultrafiltration, nanofiltration and reverse osmosis) for heavy metal removal was conducted. The work aimed assess primary quantitative attributes research this field during specified period. total 2205 were identified, corresponding analysis indicated an exponential growth number publications over time. contribution three most productive countries (China, India USA) accounts more than 47.1% publications, with Chinese institutions appearing as ones. Environmental Science frequent knowledge category (51.9% contribution), followed by Chemistry Chemical Engineering. relative frequency keywords a complete network allowed conclusion that low-pressure (microfiltration ultrafiltration) have been deeply investigated high-pressure (nanofiltration osmosis). Although porous membranes are not adequate dissolved metals ionic forms, incorporation embedded adsorbents within structure auxiliary chemicals form metallic complexes or micelles can be retained type promising approaches. High-pressure achieve rejection percentages above 90% (99% case osmosis), but they imply lower permeate productivity higher costs due required pressure gradients.
