Due to the impact of climate change, the process of salinity intrusion occurs frequently in coastal areas of Vietnam. Therefore, the main objective of this study is to evaluate the brackish water treatment capacity of different nanofiltration (NF) processes for domestic and drinking water supply for residential areas in Thu Bon river basin, where the salinity varies significantly within seasons. | Brackish water treatment reasearch in pilot scale using dual stage nanofiltration for domestic - drinking water supply in Thu Bon river basin
