a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter. The operational pressure is 0.3-2 MPa. The nanofiltration membrane removes particles with size more 2 nm.
