Retention measurements of nanofiltration membranes with electrolyte solutions
TL;DR: Retention measurements with single salt solutions of CaCl2, NaCl and Na2SO4 revealed that the rejection mechanism of commercial polymeric nanofiltration membranes investigated in this study may be divided into two categories: positively and negatively charged membranes, and membranes for which Donnan exclusion seems to play an important role.

Performance of an ultra-low-pressure reverse osmosis membrane (ULPROM) for separating heavy metal: effects of interference parameters
TL;DR: In this article, an experimental investigation was conducted to study the performance of an aromatic polyamide (ES 20) ultra-low-pressure reverse osmosis membrane (ULPROM) for separating divalent (Cu 2+, Ni 2+ ) and hexavalent (Cr 6+ ) heavy metals from bulk solution.
Journal ArticleDOI
Water and salt transport through two types of polyamide composite membranes
TL;DR: The water and salt transport through two different negatively charged polyamide composite membranes, FT30 and NF40, in spiral-wound element form have been examined in this article, where a model with coupled transport between salt flux and water flux correlated experimental data on magnesium sulfate solutions for the NF40 membrane.

Low-pressure RO membrane desalination of agricultural drainage water
Ron-Wai Lee,Julius Glater,Yoram Cohen,Christopher J. Martin,Kurt Kovac,Martin N. Milobar,Dan W. Bartel +6 more
TL;DR: In this article, a diagnostic approach to membrane selection and process evaluation was undertaken in support of a pilot field study in the California San Joaquin Valley, where five candidate membranes were evaluated in a diagnostic laboratory membrane system which provided an initial selection based on salt rejection and product water flux performance.

A novel measurement method of Donnan potential at an interface between a charged membrane and mixed salt solution
TL;DR: In this paper, the authors developed a measurement method of the Donnan potential difference at a charged membrane/salt solution interface, which can measure the potential under the condition that the membrane charge density is much lower than the KCl concentration of the salt bridge.
