The projections recently published by the United Nations (UN) suggest that the global population may reach 8.9 billion people by the year 2050. Life expectancy is assumed to rise constantly with no upper limit and by the year 2100 is expected to vary from 66 to 97 years. As the population ages the demand for effective medicines is rising. At the same time the pharmaceutical industry keeps applying pressure to shorten development timelines for new chemical entities, so that new medicines can reach patients much faster.

The main objective of this work was to develop predictive models for nanofiltration (NF) membrane processes. A one-parameter model (pore radius) for uncharged solute rejection has been developed. The good agreement between the proposed model and experimental data confirmed that uncharged solute rejection is well described by continuum models. A two-parameter model (pore radius and membrane charge) for electrolyte rejection has also been developed. Dielectric exclusion was included as an energy barrier to ion partitioning into the pores, the reassessment of which using NaCl rejection at the mem

Nanofiltration by its nature is used to concentrate material. It has been found that varying the solute feed concentration had an effect on the rejection of amino acids and polar molecules. The rejection of these organic solutes has been shown to increase with concentration during nanofitration experiments for a NTR 7450 membrane. The rejection of glycine increased from 29.4% to 72.2% for a concentration of 0.004 g/1 and 4.0 g/1 respectively. Similar increases in rejection with respect to concentration were observed for glutamine and glutamic acid, as well as for glucose, sucrose and raffinose

Although nanofiltration (NF) has attracted increasing attention over the recent years, its current industrial applications are still limited compared to the great potentialities of this clean process. The major reason is that the physical phenomena involved in separation at the nanoscale are still poorly understood and the relative success of current NF models can be attributed in large part to the fact that key properties of membranes (like their surface charge density) and confined fluids (like the dielectric constant of the solution in the membrane pores) are most often fitting parameters t

La nanofiltration est un procede membranaire utilise dans des secteurs aussi divers que l'industrie alimentaire, automobile ou pharmaceutique. La modelisation des processus de transfert et de separation de la matiere a travers les nanofiltres est delicate car ceux-ci resultent de la combinaison de nombreux phenomenes physico-chimiques complexes. Les principales etapes de ce travail sont les suivantes : - description des principaux mecanismes de transport et de retention des especes en solution aqueuse par une membrane solide a travers laquelle on impose une difference de pression hydrostatique

This thesis offers a comprehensive study that analyses the relationship between polyimide (PI) organic solvent nanofiltration (OSN) membrane formation parameters, membrane structure, and membrane functional performance. The dissertation starts by addressing the structure-related problem of macrovoid formation, which arises when more open membranes are prepared. Incorporation of TiO2 nanofillers into the membrane matrix results in macrovoid-free, organic/inorganic PI/TiO2 mixed matrix membranes without compromising rejection. Subsequently, a detailed analysis of the membrane formation process,

The need for searching an alternative technology to separate solvent efficiently from the post-extraction process in the algae fuel production process has been long researched for, and little to no convincing findings were found to rectify the current energy crisis. This report aims to evaluate the viability of implementing nanofiltration technology that could replace the use of a distillation column in the post-extraction process. Aspen Plus was used to assess the thermodynamic feasibility of utilising chemical process unit operations. This includes the following: investigation of the effect

La part des technologies membranaires en tant que technique de séparation a rapidement augmenté au cours de ces dernières années grâce à leur large gamme d'applications. Le marché en pleine expansion nécessite des matériaux polymères avancés qui montrent une résistance accrue vis-à-vis du gonflement et de la plastification en séparation de gaz (GS) ou vis-à-vis de solvants forts et des conditions de pH extrême en nanofiltration en milieu organique (SRNF). Aujourd'hui, la réticulation apparait comme une technologie prometteuse pour répondre à ces nouveaux besoins. La réticulation chimique est l

Cette étude a été consacrée à la purification et au fractionnement de mélanges de cyclodextrines par procédés membranaires (NF, UF). Les cyclodextrines (CD) sont des oligosaccharides cycliques constituées de 6 à plus de 60 unités de glucose (CD6-CD60). Elles sont synthèsées en mélange à partir de la bioconversion de l'amidon. Dans un premier temps, la complexation ultrafiltration a été appliquée pour séparer la CD6 et la CD7. Au cours de cette étude, différents paramètres comme la pression, le rapport stœchiométrique entre CD et agent complexant et le rapport massique entre CD ont été étudiés.

Aujourd'hui, la nanofiltration (NF) est perçue comme un procédé de séparation efficace et propre permettant d’extraire ou de concentrer des solutés ioniques ou neutres. Son développement à l’échelle industrielle n’est cependant pas encore optimal car les différents mécanismes de séparation sont encore mal compris. Cette thèse a porté d’une part sur l’étude des propriétés charge de surface des membranes de NF/OI et d’autre part sur les mécanismes de transport à travers des membranes de NF. Il a tout d’abord été montré, grâce à des mesures électrocinétiques réalisées sous atmosphère contrôlée, q
