Comparison of reverse osmosis and nanofiltration membranes in water purification process

Özet

Water is indispensable for the continuation of life. However, fresh water resources in the world are decreasing day by day. For this reason, effective management of existing water resources and treatment of wastewater becomes important. In this study, two prominent membrane filtration processes in water treatment, reverse osmosis and nanofiltration processes, were compared. In this comparison, commercial NF90 nanofiltration membrane and BW30 reverse osmosis membrane from the same manufacturer were used. Tap water, 2000 ppm NaCl and ultrafiltration filtrate of synthetic oily solution were chosen as the feed solution. Only pretreatment was carried out by ultrafiltration process. Although the total dissolved solids rejection rates of both membranes are close to each other, the flux obtained with the NF90 membrane is approximately twice the flux obtained with the BW30 membrane at all pressure values. Since both membranes consume the same amount of energy in water treatment, it has been concluded that water treatment with NF membranes is more economical.
