Nanofiltration

Nanofiltration is a pressure-driven membrane separation process between reverse osmosis and ultrafiltration, with nanofiltration membranes having pore sizes in the range of a few nanometers.Nanofiltration (NF) is used to separate substances with small relative molecular masses, such as inorganic salts or small organic molecules such as glucose and sucrose, from solvents. Nanofiltration, also known as low-pressure reverse osmosis, is an emerging field of membrane separation technology with a separation performance between reverse osmosis and ultrafiltration, allowing some inorganic salts and certain solvents to pass through the membrane, thus achieving separation.

Nanofiltration membrane filter(NF) is more and more widely used in electronic, food and pharmaceutical industries , such as ultra pure water preparation, fruit juice high concentration , peptide and amino acid separation, antibiotic concentration and purification, whey protein concentration.Compared with Ultrafiltration or Ro system ,the Nanofiltration has poor retention of univalent ions and organics with molecular weight between 200 and 500 .

FEATURES AT A GLANCE
1.Continuous operation, continuous feeding and continuous discharging

2. Anti pollution, anti oxidation, acid and alkali resistance (ph1-13), working

3. Compare with RO system , The NF have high permeation flux under high salinity and low pressure .

Final Product For Reference
Main application :
1. Pharmaceutical (desalination and concentration of antibiotic resin analytic solution, vitamin concentration)
2. Dye (desalting and concentration, replacing salting out and acid out ).
3. Amino acids (decolorization, impurity removal, concentration, desalination)
4. Food (oligosaccharide, starch sugar separation and purification,, fruit juice concentration, plant extraction).
5. Water treatment(printing and dyeing wastewater treatment, reclaimed water reuse, waste acid and alkali preparation).
6. Acid and alkali recovery(waste acid and alkali from column washing in pharmaceutical industry , waste acid and alkali from chemical fiber industry)

What is the difference between ultrafiltration and nanofiltration?

Ultrafiltration removes bacteria, protozoa and some viruses from the water. Nanofiltration removes these microbes, as well as most natural organic matter and some natural minerals, especially divalent ions which cause hard water. Nanofiltration, however, does not remove dissolved compounds
