Organic Solvent Nanofiltration in Pharmaceutical Industry

Crosslinked polybenzimidazole membranes for organic solvent nanofiltration (OSN): Analysis of crosslinking reaction mechanism and effects of reaction parameters

“…The compound (3) which is then formed can undergo further alkylation and can give a di-substituted imidazole moiety (4). Hence, these reactions give a mixture of compounds (2), (3) and (4). It has been suggested that the formation of compound (4) is favoured when an excess of alkylating agent is present and can be formed directly from imidazole [27].…”

Multi-scale modelling of OSN batch concentration with spiral-wound membrane modules using OSN Designer

“…In industrial membrane concentration processes, such as the recovery of a valuable compound in the pharmaceutical industry, or the recovery of solvents in the chemical industry, often the membrane rejection is high but not total (100%) [Buonomenna and Bae, 2015]. In this case it is very important to control the loss of solute to permeate during the process.…”

Nanofiltration membrane achieving dual resistance to fouling and chlorine for “green” separation of antibiotics

“…Most recently, nanofiltration with unique characteristics of narrow pore size distribution and high surface charges attracts great attention for solving environmental and energy issues [5][6][7][8][13][14][15][16][17]. Majority of the commercial NF membranes (e.g.…”

“…As a green and energy conservation technique, membrane separation has been currently exploited in broad fields featuring nearly zero emissions and no harmful additives [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Most recently, nanofiltration with unique characteristics of narrow pore size distribution and high surface charges attracts great attention for solving environmental and energy issues [5][6][7][8][13][14][15][16][17].…”
