In view of the high risks brought about by organic micropollutants (OMPs), nanofiltration (NF) processes have been playing a vital role in advanced water and wastewater treatment, owing to membrane performance rejection OMPs, permeation water, passage mineral salts. Though numerous studies devoted evaluating technically enhancing removing various trade-off effect between permeance water/OMP selectivity for state-of-the-art membranes remains far from being understood. Knowledge this is significant comparing guiding development works toward cost-efficient OMP removal. work, we comprehensively assessed 88 NF membranes, commercialized or newly developed, based on their data published literature. The effectiveness underlying mechanisms modification methods tailoring properties turn mainstream polyamide (PA) thin-film composite (TFC) were quantitatively analyzed. was demonstrated abundant both experimental measurements machine learning-based prediction.

Mono-/multivalent ion-selective separation has become a common requirement at the water-energy nexus, including energy storage and conversion, water purification, sustainable industrial processes. In this review, we summarize theory of ion transport through membrane mechanisms selective in nanofiltration (NF) briefly. Recent advancing improving mono-/multivalent selectivity thin-film composite (TFC) NF via size sieving enhancement, electric charge property regulation co-enhancement properties are concluded. What's more, three material classes—surface assembly materials, nanomaterials biomimetic channels highlighted as candidates for preparation membranes. Lastly, design directions critical challenges developing high-selectivity membranes based on provided.

Fast permeation and effective solute-solute separation provide the opportunities for sustainable water treatment, but they are hindered by ineffective membranes. We present here construction of a nanofiltration membrane with fast permeation, high rejection, precise Cl-/SO42- spatial temporal control interfacial polymerization via graphitic carbon nitride (g-C3N4). The g-C3N4 nanosheet binds preferentially piperazine tiles water-hexane interface as revealed molecular dynamics studies, thus lowering diffusion rate PIP one order magnitude restricting its pathways towards hexane phase. As result, membranes nanoscale ordered hollow structure created. Transport mechanism across is clarified using computational fluid simulation. Increased surface area, lower thickness, identified key contributors to permeance 105 L m2·h-1·bar-1 Na2SO4 rejection 99.4% selectivity 130, which superior state-of-the-art NF Our approach tuning microstructure enables development ultra-permeability excellent ion-ion separation, purification, desalination, organics removal.
