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.

Tweak in Puzzle: Tailoring Membrane Chemistry and Structure toward Targeted Removal of Organic Micropollutants for Water Reuse

Environmental Science & Technology Letters, Journal Year: 2022, Volume and Issue: 9(4), P. 247 - 257

Published: March 25, 2022

Membrane-based water reuse through reverse osmosis (RO) and nanofiltration (NF) faces a critical challenge from organic micropollutants (OMPs). Conventional polyamide RO NF membranes often lack adequate selectivity to achieve sufficient removal of toxic harmful OMPs in water. Tailoring membrane chemistry structure allow highly selective has risen as an important topic membrane-based reuse. However, literature gap remains be addressed: how design for more OMPs. In this review, we critically analyzed the roles on highlighted opportunities strategies toward context Specifically, statistically rejection by conventional illustrate their drawbacks removal, followed discussion underlying fundamental mechanisms. Corresponding tailor properties improving against OMPs, including surface modification, nanoarchitecture construction, deployment alternative materials, were systematically assessed terms permeance, rejection, water–OMPs selectivity. end, discussed potential challenges various scale-up real applications.
