Nanofiltration refers to a speciality membrane process which rejects particles in the approximate size range of 1 nanometer (10 Angstroms), hence the term "Nanofiltration." NF operates in the realm between UF and reverse osmosis. Organic molecules with molecular weights greater than 200-400 are rejected. Also, dissolved salts are rejected in the range of 20-98%. Salts which have monovalent anions (e.g. sodium chloride or calcium chloride) have rejections of 20-80%, whereas salts with divalent anions (e.g. magnesium sulfate) have higher rejections of 90-98%. Typical applications include removal of color and total organic carbon (TOC) from surface water, removal of hardness or radium from well water overall reduction of total dissolved solids (TDS), and the separation of organic from inorganic matter to specialty food and wastewater applications. Transmembrane pressures are typically 3.5 to 16 bar (50 to 225 PSI).

Nanofiltration (NF), in water treatment, “bridges” a gap between ultrafiltration and reverse osmosis membranes. It is sometimes referred to as a loose or lower rejecting RO membrane. It could also be called a tight UF, as NF membrane pore size ranges from .01 to a little less than .001. Generally, an NF membrane system lets more salt pass than an RO membrane. In addition, an NF membrane element will produce the same quantity of product at 50 to 70% the applied pressure as an RO water treatment system.

There are applications where a 75% rate of salt rejection is preferable to 95 to 99%, especially when it is achieved using only half of the energy. Unlike with RO membrane elements, the NF offerings of the major membrane manufacturers are quite different in performance from company to company. With RO membrane elements, any model with less than 99.5% sodium chloride rejection, especially with seawater membranes, is considered inferior. In the case of NF, there is a “place” for any membrane with a NaCl rejection rate of 40%, or more. Nanofiltration has also been called a “softening” membrane as while its salt rejection may be 80% or less, hardness rejection will often remain well over 90%.

Product Details:

NF delivers slightly coarser filtration than RO, with the ability to remove particles as small as 0.002 to 0.005 μm in diameter. NF is a relatively recent technology that was developed mainly for potable water generation. NF removes harmful contaminants, such as pesticide compounds and organic macromolecules, while retaining higher levels of minerals that RO would otherwise remove. Today's RO systems retain traces of minerals to ensure water tastes well and is safe to consume. Nano-filtration membranes are capable of removing larger divalent ions such as calcium sulfate while allowing smaller monovalent ions such as sodium chloride to pass through.

Difference between nanofiltration and reverse osmosis?

While nanofiltration and reverse osmosis systems have similar designs and operation uses, there are some notable differences between the two. The primary distinction is that nanofiltration is not as rigid as reverse osmosis. It functions with less feed water pressure and is incapable of removing single charge ions from the water as definitely as reverse osmosis membranes.

While up to 99% of chlorides and sodium are removed by reverse osmosis systems, nanofiltration membranes typically remove only 50% to 80%. This percentage relies on the type of material and manufacturing of the membrane. However, due to its effectiveness in removing multiple charge ions, nanofiltration is the preferred choice for removing hardness from water while not affecting the total dissolved solids content than would reverse osmosis. 

Does nanofiltration remove chlorine?

NF can reduce or remove TDS, hardness, color, agricultural chemicals, high molecular-weight, fulvic materials (which can form trihalomethanes when chlorinated). NF is also used to remove both organics and inorganics from different wastewaters.
