Rejection of ammonium and nitrate from sodium chloride solutions by nanofiltration: Effect of dominant-salt concentration on the trace-ion rejection
(Elsevier, 2016-06-04)
Article
Accés obertIn this work, the rejection of two ions associated with fertilizer pollution of ground water (NH4+ and NO3-) by a polyamide nanofiltration (NF270) membrane was studied. Sodium chloride was selected as the dominant salt and ... -

Rejection of minor ionic solutes in nanofiltration : influence of solution composition
(2012)
Article
Accés obertNanofiltration (NF) is a membrane separation process used in water treatment for ion separations, taking advantage of different selectivities toward various ions, higher fluxes and lower energy requirements than in reverse ... -
Rejection of trace ionic solutes in nanofiltration: Influence of aqueous phase composition
(2013-12-18)
Article
Accés restringit per política de l'editorialThe use of nanofiltration (NF) in water treatment has been proposed to improve the quality of the produced water and extend the options of concentrate valorization, taking the benefit of its different ions selectivity ... -
Role of imperfections in transfer of organic micro-pollutants through RO/NF membranes: Numerical study
(Elsevier, 2023-12-15)
Article
Accés restringit per política de l'editorialDue to relatively low diffusivities, the rejection of organic micro-pollutants in pressure-driven membrane processes is more affected by Concentration Polarization (CP) than that of typical inorganic ions. On the other ... -
Selective transport of trivalent lanthanide in electrodialysis: Limitations due to concentration polarization
(Elsevier, 2023-11-05)
Article
Accés restringit per política de l'editorialExtraction of rare-earth ions from mixtures with other cations is an important part of recovering rare-earth ions from recycling or other streams. This study examines whether highly selective Donnan partitioning into a ... -
Separation of ions using polyelectrolyte-modified nanoporous track-etched membranes
(2013)
Article
Accés restringit per política de l'editorialSelective ion exclusion from charged nanopores in track-etched membranes allows separation of ions with different charges or mobilities. This study examines pressure-driven transport of dissolved ions through track-etched ... -
Solution-diffusion–electro-migration model and its uses for analysis of nanofiltration, pressure-retarded osmosis and forward osmosis in multi-ionic solutions
(2013-11-15)
Article

Transient membrane potential after concentration step: A new method for advanced characterization of ion-exchange membranes
(2019-09-01)
Article
Accés obertA better understanding of ion-transport mechanisms requires separate information on the equilibrium (partitioning) and kinetic (diffusivity) properties of the membranes with respect to ions. This work presents a novel ...
