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.
