Industrial Membrane Nanofiltration NF Systems NF-400

Quality Systems at an exceptional value
Industrial Membrane Nanofiltration NF Systems NF-400
Product Description

Pure Aqua’s nanofiltration is a membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter. Nanofiltration is also becoming more widely used in food processing applications such as dairy, for simultaneous concentration and partial (monovalent ion) demineralization.

Pure Aqua supplies a full line of standard and fully customizable nanofiltration systems, all of which are engineered using advanced 3D computer modeling and process design software for accurate and customized solutions.

Here at Pure Aqua, Inc., we engineer and build all of our water treatment systems in-house.

Our turn-key water treatment systems are all pre-engineered using the latest CAD technology available.

This enables our teams to build and deliver treatment systems to our customers with quick turnaround times.

Many of our customers require custom engineered systems. These are typically built around similar core systems and thus allowing for improved turnaround times, even for one-off designs.

    great softening membrane system

    Posted by Michael Salzar on Jun 3rd 2024

    We bought a nanofiltration system to replace our conventional water softener, it was the best thing we did, we saved money on salt and operation. Water quality is superior, great product.
