Nanofiltration is mainly utilized for producing softened water for industry or potable water from a brackish source. This type of semi permeable membrane has high rejection of multi valent ions such as Calcium and moderate rejection of single valent ions such as Sodium. These properties allow this type of membrane to operate at greatly reduced operating pressures as compared to Reverse Osmosis.Anderson skids utilize the highest quality spiral membranes fromWorld leading membrane suppliers. High efficiency membranesand low operating pressures are combined to manufacture the mosteconomical skid to meet all client requirements.
The fundamental principle of Nanofiltration membrane technology
is the use of pressure to separate soluble ions from water through
a semi permeable material. The membrane, unlike a dead end
filter, operates under a different hydraulic profile which is known
as cross flow filtration.
Most Nanofiltration membranes are composite materials that are
supported by a polymer substrate and manufactured in a spiral
configuration as opposed to a flat sheet or tube geometry. The
predominant model used today for industrial applications is the
spiral configuration.
