Nano Filtration NF Systems

The fundamental principle of Nanofiltration membrane's technology is the use of pressure to separate soluble ions from water through a semi permeable membrane. The membrane, operates under a different hydraulic profile which is also known cross flow filtration, unlike a dead end filter.

Most Nanofiltration membranes are composite materials supported by polymer substrate and manufactured in a spiral design as opposed to a flat sheet or tube geometry. The predominant model used today for industrial applications is the spiral configuration. To ascertain further understanding of nanofiltration systems, you will need to be aware of the following information.

Like RO, and unlike UF, Nanofiltration Systems will recover a percentage of the feed water. Most all NF membranes are of a spiral wound configuration.
