Various methods are used to prepare potable water with environmental standards. Among them, membrane filtration has received particular attention in recent years for low operating costs, low volume wastewater and high quality water. Among the conventional membrane filtration methods, nanofiltration ones have been further developed due to high capability to remove divalent ions and low energy consumption compared to reverse osmosis membranes. In this study, performance of polymer membrane TFC-HR-100 in removal of copper ions from the copper sulfate in aqueous solutions has been investigated. Polymer membrane TFC-HR-100 from the nanofilter and composite category is used to remove divalent ions. In the experiments performed, elimination of the impurities of the divalent copper ions from aqueous solutions with concentrations ranging from 100 ppm to 5000 ppm at 5-25 bar pressures has been studied .
