In the current study, the effect of operating conditions such as pH value, feed flow, concentration of the solution and the applied pressure for the removal of copper(II) and iron(III) mixtures for the production of drinking water by nanofiltration membrane was investigated. The results show that it is possible to extract all of the iron (III) and copper (II) at the same time to a salt mixture of Fe 50% - salt Cu 50% for concentration 4 ppm, pH = 4.5 and pressure = 6 bars. The best results for the copper (II) were obtained for the various mixtures at the pressure of 6 bars at varying pH.
