X – Series

With models ranging from 20 to 125 gallons per minute (30,000 to 180,000 gallons per day), the smart, clean utilitarian industrial design of the X – Series allows for convenient installation, user-friendly operation and ease of maintenance. These skid-mounted, package systems are pre-plumbed and pre-wired on a powder-coated steel frame complete with a pre-programmed controller, TDS probes and panel-mounted pressure gauges and flow instrumentation, allowing for straight forward system monitoring and control. X – Series  systems may be upgraded with the AXEON NF3 or NF4 membrane elements designed to provide low operating pressure for nanofiltration applications.

Nanofiltration (NF) membrane technology is the use of pressure to seperate soluble ions from water through a semi permeable membrane. The membrane operates under a different hydraulic profile which is also known as cross flow filtration. NF in water treatment bridges a gap between Ultrafiltration (UF) and Reverse Osmosis (RO) membranes. It is sometimes referred to as a loose or lower rejecting RO membrane. It could also be called a tight UF, as NF membrane pore size ranges from .01 to a little less than .001. Generally, an NF membrane system lets more salt pass than an RO membrane. In addition, an NF membrane element will produce the same quantity of product at 50 to 70% the applied pressure as an RO water treatment system

Nanofiltration Systems are membrane filtration systems used most often on applications that require higher TDS permeate, such as surface water and groundwater, with the purpose of softening (polyvalent cation removal) and removal of by-product precursors like natural organic matter and synthetic organic matter. Nanofiltration is also becoming more widely used in food processing applications for simultaneuous concentration and partial (monovalent ion) demineralization.
