"In this study, four types (Esna 1, Desal 5 DK, NF 70, TR 60) of nanofiltration membranes were tested to evaluate optimal operating conditions for flux values and salt rejection in reactive dye/salt mixtures separations. Effects of pressure and feed composition were investigated. Experiments showed that feed composition had a significant effect on flux values. Donnan effect had a significant effect on salt rejection. From tested membranes was chosen one membrane and batch diafiltration at constant applied pressure and constant volume was performed on chosen membrane. Main purpose of diafiltration experiments was to measured dependence of eliminated salt and of concentration of the salt in feed on the time."@en .
