For industrial applications requiring precise separation and high productivity at low operating pressures, the AXEON NF Series Nanofiltration Membranes stand out as a premier solution. As a distributor for leading water treatment technologies, Purecowater provides these advanced membrane elements designed to tackle complex solid and liquid filtration challenges.

Overview: Precision in Nanofiltration
The AXEON NF Series utilizes proprietary Polyamide Thin-Film Composite technology to deliver superior performance. These membranes are engineered to bridge the gap between reverse osmosis and ultrafiltration, offering high rejection of organics, bacteria, and viruses while allowing a controlled passage of monovalent salts. This unique selectivity makes them ideal for water softening, color removal, and process separation.
AXEON manufactures these elements with industry-leading film technology, ensuring reliability and cost savings through lower energy consumption [axeonwater.com].
AXEON NF Series Breakdown
The NF Series is categorized based on specific rejection capabilities and application requirements. Whether you need to remove pesticides, soften water, or separate dyes, there is a specific configuration for your system.
1. NF3 Series: Energy Efficient Nanofiltration
The NF3 Series is designed for low-energy consumption while maintaining high productivity. These elements are excellent for partial desalination and hardness removal, operating effectively at lower pressures compared to standard RO membranes. They are widely used in commercial applications where utility costs are a significant factor [uswatersystems.com].
2. NF4 Series: Organics and Chemical Removal
The NF4 Series excels in removing a high percentage of salts, nitrates, iron, and organic compounds such as pesticides, herbicides, and THM precursors [axeonwater.com]. Due to low net driving pressure, these membranes remove contaminants efficiently without requiring extreme operating pressures.
| Part Number | Model | Permeate Flow (GPD) | Applied Pressure (psi) | Ideally Suited For |
|---|---|---|---|---|
| 200407 | NF4 – 2514 | 200 | 70 | Small Commercial / Pilot |
| 200409 | NF4 – 2540 | 680 | 70 | Commercial Systems |
| 200412 | NF4 – 4040 | 2,000 | 70 | Industrial Filtration |
3. NF5 Series: Water Softening and Color Removal
The NF5 Series is engineered to remove polyvalent ions (like Calcium and Magnesium) while allowing a higher passage of monovalent salts. This characteristic makes them perfect for water softening without total desalination. They extensively used in the Food and Beverage industry to remove color, odor, and taste, and in wastewater treatment to reduce total organic carbon (TOC) by up to 95% [axeonsupply.com].
