FilmTec™ Nano Filtration Membranes

The ideal nanofiltration membrane has a very high water permeability, but the ideal permeability of solutes might be near zero or some higher value, depending on the solute and application. For example, an application may require near-zero permeability for pesticides and 50% permeability for calcium ions.

Typical application of nano filtration membrane systems include:

• The removal of colour and total organic carbon (TOC) from surface water
• The removal of hardness or radium from well water
• The overall reduction of total dissolved solids (TDS).
• The separation of organic from inorganic matter in speciality food and wastewater applications.
