WebNanofiltration membranes are defined as having a pore size in the order of nanometers (nm) (1×10−9 m). As a comparison, the atomic radius of a sodium ion and a chlorine ion is about 0.97 nm (0.97×10 −9 m) and 1.8 nm (1.8×10 −9 m), respectively. This demonstrates that nanofiltration membranes are near the range to remove rather small ions.
