"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 concentration on the salt rejection and flux as well as comparison of individual NF membranes for desalting purposes 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 (see Fig. 1) and the influence of this phenomenon on permeate flux. It was also shown that extended Spiegler-Kedem model including Donnan exclusion mechanism can sufficiently predict salt rejections even at high concentration typical for desalting process."@en .
