Characterisation of Nanofiltration Membranes for the Separation of Aqueous Dye-Salt Solutions.

Popis výsledku v původním jazyce

The main objective of the present work was to study the process of nanofiltration of aqueous dye-salt solutions in order to describe the process of desalting of organic dyes by polymeric nanofiltration membranes. Nanofiltration experiments were carried ofor differnet dye-salt ratios and different pressures. Experiments of basic nanofiltration membrane characterisation (permeation of single monovalent or bivalent salt solution) were carried out as well. All experimental data were analysed by extended Spiegler-Kedem model. Very good prediction was obtained for salt permeation. Prediction of performance of nanofiltration of aqueous solutions characterised by salt retention was possible even for high dye concentrations typical for desalting process. Also comparison of salt retention and permeation rate for dye-salt solutions for three commercial membranes (spiral wound modules) was carried out.
