Oltremare NF

Our Oltremare NF membranes are designed to meet specific customer requirements, delivering high-performance results.

Nanofiltration plays a crucial role in various drinking water purification processes, including water softening, decolorization, and micropollutant removal. In industrial applications, nanofiltration effectively removes specific components such as coloring agents. This pressure-driven process relies on the separation of substances based on ionic charges and molecular size.

The primary focus of nanofiltration is the removal of organic substances like micropollutants and divalent ions, with elements demonstrating low to moderate retention for monovalent salts.

Main Applications

Key applications of nanofiltration include:

  • Removal of pesticides from groundwater
  • Removal of heavy metals from wastewater
  • Water softening, serving as an alternative to ion exchange softeners
