The main objective of this study is therefore to try diff erent nanofi ltration (NF) processes (such as single-stage and dual-stage NF) to treat brackish water for residential areas in Thu Bon river basin, where the salinity varies signifi cant with seasons. Results have shown that during the rainy season, the salinity was less than 8.5‰, so the single stage NF worked perfectly. When season changes from rainy season to dry season, the river’s salinity increases up to 17.5‰, application of dual NF is most appropriate. This dual NF process not only guarantees the effl uent quality to meet National Technical Regulation, but also off ers reasonable energy cost and fi nally can prolong the membrane lifespan.
