Nanofiltration is a water treatment process that falls between reverse osmosis and ultrafiltration in terms of membrane pore size. It uses semi-permeable membranes with smaller pores than those in ultrafiltration but larger than those in reverse osmosis.
Nanofiltration is effective at removing various contaminants from water, including ions, organic matter, and some larger molecules. It’s commonly used for softening water, reducing hardness, and improving water quality by selectively allowing certain substances to pass through while retaining others.
Overall, the selective and efficient nature of nanofiltration makes it a valuable tool in achieving specific water treatment standards while maintaining a balance between contaminant removal and resource efficiency.
