Separation of Aqueous Dye-Salt Solutions by Nanofiltration: Analysis of Negative Salt Rejection.

Original language description

The process of desalination of aqueous dye-salt solutions by polymeric nanofiltration membranes using commercially available modules was studied. The influence of dye and salt concentrations on the salt rejection and flux is presented. Extended Spiegler-Kedem model including Donnan exclusion mechanism and the term of concentration dependence of salt permeability was used for prediction of salt rejection. The experimental results show negative salt rejections during the desalination and the dependence ofthis phenomenon on permeate flux. It was also shown that extended Spiegler-Kedem model including Donnan exclusion mechanism can satisfactorily predict salt rejections even at high concentrations typical for desalting processes.
