Nanofiltration Membranes

• Unmatched performance
• Sanitary design
• Longer service life

Further Details:

Nanofiltration is a membrane segregation process, it separates an array of organic and inorganic substances from solution in a liquid. This is achieved by dissemination through a membrane, under pressure differentials that are substantially less than those required for reverse osmosis but still considerably greater than those for ultra filtration.

All nanofiltration systems rely heavily on membranes. The membranes are produced from a wide gamut of materials like cellulose derivatives, synthetic polymers, ceramics and also from organic/inorganic hybrids. Furthermore, the membranes are also produced in varying formats, such as plate and frame form, spiral wound, tubular, capillary etc.

Nano filtration, similar to other membrane processes is also vulnerable to fouling. So nano filtration systems should be designed in such a way as to minimize the likelihood of fouling.This can be achieved through proper pretreatment, with the right membrane material and with sufficient cross flow velocities to wipe the surface clear of accrued slime.

Applications:

Nano filtration is commonly used in different industrial sectors, some of these are,

• It's chief application is still in the treatment of fresh, processed and waste water. Although it cannot be used for water desalination, nano filtration is used as a potent process of softening water. Furthermore, nano filtration membranes are also ideal to use in the removal of natural organic matter from water i.e- tastes, odors and colors.
• In the food industry, NF is used to concentrate whey and permeates from other whey treatments. Also used in the processing of sugar to concentrate dextrose syrup and thin sugar juice. It also finds use in dairy industry.
  
• In the chemical sector, NF is used as a purification process during the production of salt. Moreover, it is also commonly used in petrochemicals and the pharmaceutical sector.
• In the paper pulp industry, nano filtration is used for it's purification properties, helping the industry to reduce it's total water usage.
