ABSTRACT

The textile industry is a worldwide water pollution source. Considering the enormous quantities of wastewater discharged and their compositions, the wastewater generated from dyeing and nishing operations is rated as one of the most polluting among all industrial sectors, raising environmental concerns all over the world about the elimination of color and salt from the wastewater. Due to the unique characteristics in the separation of small neutral and charged molecules from wastewater streams, the use of nanoltration (NF) membranes in the treatment of textile wastewater has drawn much attention from membrane scientists over the last decade and has proven to be more suitable and reliable compared with the conventional treatment methods and other kinds of pressure-driven membrane processes.
