Utilizing brackish water resources has imposed a high requirement on the design and construction of nanofiltration membranes. To overcome limitation salt concentration separation performance resulting from weakened Donnan effect, membrane with effect salt-responsive ion valves was developed by incorporating zwitterionic nanospheres into polyamide layer (PA-ZNs). The interaction between membranes at salinity revealed through combination analysis perspectives transport model, positron annihilation spectroscopy, solute rejection, contributing to formation valve effect. PA-ZNs presented breakthrough in overcoming increased concentrations performance, achieving selectivity 105 for mono/multivalent anions. reveal role membrane, conductance determined different concentrations, confirming channel-controlled low valve-controlled salinity. Moreover, main mechanisms were systematically studied. concept may contribute expanding application treatment.

Distinct Efficacies of Interlayers in Tailoring Polyamide Nanofiltration Membrane Performance for Organic Micropollutant Removal: Dependent on Substrate Characteristics

Environmental Science & Technology, Год журнала: 2024, Номер 58(31), С. 14022 - 14033

Interlayered thin-film nanocomposite (TFN) membranes have shown the potential to boost nanofiltration performance for water treatment applications including removal of organic micropollutants (OMPs). However, effects substrates been overlooked when exploiting and evaluating efficacy certain kinds interlayers in tailoring membrane performance. Herein, a series TFN were synthesized on different porous with identical metal-organic framework nanosheets. It was revealed that interlayer introduction could narrow but not fully eliminate difference properties among polyamide layers formed substrates, variation prominent distinct aspects. For small pore sizes exerting severe transport hindrance, introduced mainly enhanced permeance by affording gutter effect, while it be more effective reducing size improving interfacial polymerization platform avoiding PA defects using large-pore-size substrate. By matching selected well, superior obtained simultaneously higher OMP rejections compared three commercial membranes. This study helps us objectively understand efficacies attain breakthroughs efficient treatment.
