Nanofiltration

With respect to the size and weight of solutes that nanofiltration membranes reject, NF operates in the realm between reverse osmosis (RO) and ultrafiltration (UF): Organic molecules with molecular weights greater than 200 – 400 are rejected. Nanofiltration membranes can effectively reject, among other contaminants:

  • Dissolved organics.
  • Endotoxins/pyrogens.
  • Insecticides/pesticides.
  • Herbicides.
  • Antibiotics.
  • Nitrates.
  • Sugars.
  • Latex emulsions.
  • Metal ions.

 
NANOFILTRATION ELEMENTS

  • Good Organic (NOM) Removal
  • Partial Softening Preserves Water Character
  • Reduced Power Consumption and Costs
  • Long Element Life
  • Delivers high productivity due to high active area
  • High cleanability due to wide cleaning pH range (1 – 12) tolerance
