PurePro® Nanofiltration (NF) membrane:

 

PurePro® Nanofiltration (NF) Membranes are designed for the people who still want to keep the natural mineral element inside the water. Nanofiltration membrane has a slightly larger pore size (0.0008 microns) than reverse osmosis membrane. Thus monovalent salts like sodium chloride (common table salt) molecules passes through the membrane but large divalent salts and other metals like iron, heavy metals..etc. are all blocked.

What is the pore size of Nanofiltration (NF)  Membrane ?

 

The Nanofiltration pore size diagram below will help you more understand the relative pore sizes of membranes and the sizes of the common impurities.

 

 

 

 

 

 

 

The pore size of RO membrane is 0.0001 microns which is smaller than the size of the Sodium Chloride Molecule which is 0.0007 micron and will not let it through. Nor will it let through germs and viruses, and organic molecules which are very much larger than the RO pore.

So an RO membrane will purify water from almost all chemicals. What can pass through the RO membrane is water and molecules smaller than the water molecule, like CO2 gas. Smaller molecules than water is generally not harmful to health. The RO Water is very pure. Bottled water manufacturers usually use reverse osmosis water filters to purify their water.

The Nanofiltration pore size at 0.0008 microns, is only slightly larger than the RO pore (0.0001 microns) and also only very slightly larger than the size of the common salt (NaCl) molecule. So it allows monovalent common salt sodium chloride to pass through but will not allow divalent calcium salts like calcium carbonate of dia 0.0009 microns to pass through. Nanofiltration and Reverse Osmosis RO membranes remove Mercury, Lead, Heavy Metals, Arsenic, all germs and viruses from water and makes hard water soft.

                                                          

 
 
PurePro® Nanofiltration (NF) membranes are designed for the people who still want to keep the mineral element inside the water.  The size of the pores on the NF membrane are 0.0008 microns allowing it to remove bacteria, viruses, heavy metals, viral contaminants, and other dangerous elements while still allowing valuable minerals to pass through, for the water ionizer to ionize and for your body to absorb.

The diagrams below from Pure-Pro Water Corp will help you better understand the concept of Nanofiltration and Reverse Osmosis.

 

 

 

Nanofiltration Membrane allows only pure water, monovalent salts and lower molecular weight divalent salts to pass through.

 

 

 

RO membrane only allows pure water to pass through. Everything else like monovalent and multivalent salts, bacteria and viruses are completely blocked.
