Nanofiltration

  "id": "MLC-T-CHM-007752",
  "term": "Nanofiltration",
  "field": "Chemistry",
  "definition": "A pressure-driven membrane separation that retains multivalent ions and dissolved organic molecules above a molecular weight cut-off of roughly 200 to 1000 g/mol, while monovalent ions are only partly retained. Its membrane pores are roughly 1 to 2 nanometres across. It runs at a higher pressure than ultrafiltration and a lower pressure than reverse osmosis.",
