Commercial Nanofiltration - Membrane Technology

Nano filtration is a pressure related process during which separation takes place based on molecule size. Nano filtration is mainly applied in drinking water purification process steps, such as water softening, decolouring and micro pollutant removal. Nano filtration is also applied in Agricultural and Business applications in the removal of specific components, such as coloring agents, sugars, dyes, surfactants, minerals, divalent salts, bacteria, proteins, particles, dyes, and total dissolved solids.

Because nano filtration uses less fine membranes, the feed pressure of the NF system is generally lower compared to reverse osmosis systems. Also the fouling rate is lower compared to RO systems.

Nanofiltration (NF) is not as fine a filtration process as reverse osmosis (RO), since the membrane pores are typically much larger. However, NF does not require the same energy to perform the separation. The differences between the two types of membrane are subtle, but distinct. Most notably, NF can reject only ions with more than one negative charge, such as sulfate or phosphate, while passing single charged ions.

Nanofiltration systems are used for water filtration, dairy and cattle farming, business, water softening, food, pharmaceutical, municipal, lake, river, and well water applications.

Nanofiltration Benefits

  • Lower operating costs
  • Lower energy costs
  • Lower discharge, Less waste water than RO
  • reduces salt (TDS) content of slightly brackish water
  • reduces pesticides, VOC's (organic chemicals)
  • reduces heavy metals
  • reduces nitrates and sulfates
  • reduces color, tannins, and turbidity
  • softens hard water
  • Chemical-Free - i.e. does not use salts or chemicals

If a higher purity water is needed or a greater impurity rejection percentage is required please see our Reverse Osmosis and Commercial Reverse Osmosis. Reverse osmosis has proven to be the most efficient means of removing up to 99% of total dissolved solids.

The Nano systems we offer have all been for specific applications where the user provides us feed water chemistry and desired product water quality and quantity info. Nano water treatment applications are typically softening related, sometimes it is dewatering to obtain a desired concentrated by product, other times it is waste water treatment, etc. If you can obtain feed water info and product water requirements we can determine if Nano is applicable.
