nanofiltration Insights

What is nanofiltration?

Nanofiltration (NF) is a membrane filtration process that sits between ultrafiltration and reverse osmosis. It's used to remove divalent and multivalent ions, natural organic matter, and some salts from water. Common applications include water softening, removal of specific contaminants, and pretreatment for reverse osmosis systems.

What other technologies are related to nanofiltration?

nanofiltration Competitor Technologies

Reverse Osmosis

Reverse osmosis (RO) is a pressure-driven membrane separation process, like nanofiltration (NF), but generally removes smaller molecules and ions. RO is a competitor because it can achieve similar separation goals, often with higher rejection rates, though possibly at higher operating pressures and costs.

nanofiltration Complementary Technologies

ultrafiltration

Ultrafiltration (UF) is a membrane filtration process that removes larger particles and molecules than nanofiltration. It is complementary because UF can be used as a pre-treatment step to remove larger foulants and suspended solids before NF, improving the NF system's performance and lifespan.
