Understanding and predicting industrial membranes performances in separation technology

Nanofiltration (NF) membranes cover a range of salt and neutral molecule selectivities that lay between reverse osmosis
and ultrafiltration membranes. This unique performance enabled a breakthrough in industry during the past decades.
Their high water permeability along with good rejection makes them usable as a replacement for different treatment processes
at a reasonable energy cost. However, there are some hindrances in the design of new NF processes and improvement of
existing ones since NF applications are mostly associated with complex transport phenomena of which modeling is difficult.
The understanding of transport phenomena through NF membranes by use of modeling and prediction may help to implement
NF membrane technology more broadly and will enlarge the NF market beyond water filtration. Considering that NF is an
industrial scale method for purification and concentration of oligosaccharides mixtures, we decided to study some industrial
membranes performances against various saccharides. We studied independently each component of the solute/membrane/
solvent system and their pair-interaction to achieve a deep theoretical knowledge. We then collected rejection data and analyzed
membrane performances while varying parameters, such as temperature and concentration. Thanks to the characterization of
the membranes and their performance, we were able to parameterize a model based on the extended Nernst-Planck equation
for rejection results. Finally, the model was assessed against mixture separations. Going forward, the outcome of this study will
enable more rigorous membrane selection for targeted industrial applications and to predict its performance.
