Nano filtration|reverse osmosis nanofiltration water system
Nanofiltration (NF), in water treatment, “bridges” a gap between ultra filtration membrane 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.
Like RO, and unlike UF, Nanofiltration Systems will recover a percentage of the feed water. Most all NF membranes are of a spiral wound configuration.

Difference between nanofiltration system and reverse osmosis system?
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.
Product detail of nanofiltration system
Nano filter can separate the color from waster water.Example nano filtration system can remove the colour for dye waster water concentrate.
Reverse osmosis nanofiltration Typical Applications
Reverse osmosis nanofiltration can be widely sued in the chemical industry,the petroleum industry,the metallurgy industry,power plants,the pulp& paper industry,the dyening industry,the pharmaceutical industry,the electronics industry,the semiconductor industry,the automobile industry and otherindustries,for water softening,Low molecular organic classified comcentrate, water deionization and purification and comcentrate.
Buying Guides for Nano filtration|reverse osmosis nanofiltration water system
To find the most appropriate nanofiltration system for your use, please have the following information ready
· Product water flow rate ( m3/hr, m3/day, Liter/hr,GPM,GPD etc.)
·· Product water purpose(industry process or others)
· Feed Water TDS (Total dissolved solids). Is it from Borehole/salt/brackish/lake water
· Iron
· Manganese
· TSS(Total Suspended Solid)
· SDI(Silting Density Index)< 3
· Water must be free from oils and grease
· Chlorine must be removed
· Power (110/220/380V/415V/460V, 50 or 60 Hz) 3 phase.
· It is necessary to make water analysis reprot for borehole water,lake water, seawater.
· If soure water is tap water no need end to us TDS or water analysis report.
