Nanofiltration - Wikipedia
网页Nanofiltration is a membrane filtration process that uses nanometer sized pores through which particles smaller than about 1–10 nanometers pass through the membrane. Nanofiltration membranes have pore sizes of about 1–10 nanometers, smaller than those used in microfiltration and ultrafiltration, but a slightly bigger than those in reverse ...
Nanofiltration (NF) - DuPont
网页Nanofiltration (NF) is a membrane liquid-separation technology sharing many characteristics with reverse osmosis (RO). Unlike RO, which has high rejection of virtually all dissolved solutes, NF provides high rejection of multivalent ions, such as calcium, and low rejection of monovalent ions, such as chloride.

Recent Advances in the Theory and Application of Nanofiltration: …
网页2022年1月20日 · Nanofiltration (NF) is the fourth type of pressure-driven membrane appeared after microfiltration (MF), ultrafiltration (UF), and reverse osmosis (RO) . NF was first developed in the late 1970s; it is a variant of RO membrane.
Nanofiltration membranes and processes: A review of research …
网页2017年10月1日 · Nanofiltration membranes operate with no phase change and typically have high rejections of multivalent inorganic salts and small organic molecules at modest applied pressures. This makes the separation process highly competitive in terms of selectivity and cost benefit when compared to traditional separations.
