Abstract
AbstractBACKGROUNDTransport of organic acids through nanofiltration membranes varies considerably under different conditions. In the present work, a Maxwell–Stefan approach coupled to the Henderson–Hasselbach equation was applied to describe succinic acid permeation through nanofiltration membranes in binary and ternary solutions. Permeate flux and solute rejection were evaluated under several test conditions, by modifying variables such as pH, gauge pressure, succinic acid concentration and presence of other solute (glucose, as a neutral solute).RESULTSThe model performed well in describing all experimental results for succinic acid/water binary solutions, except for pH values close to the isoelectric point of the membranes, due to electroviscous effect changes. It was also noticed that other effects, such as solvation, are important and it is necessary to include them into the model for ternary solutions.CONCLUSIONSThe Maxwell–Stefan model was able to describe the succinic acid binary solution nanofiltration performance. © 2020 Society of Chemical Industry (SCI)
