Nanofiltration Membrane Element 8040 And 4040

NF98 Series Nanofiltration Membranes – High-Performance Water Treatment Solutions

The NF98 series nanofiltration membrane elements are engineered with a proprietary multilayer composite membrane combined with nano-level ultra-thin hydrophilic coating technology. This advanced design delivers outstanding anti-fouling performance, ensuring long membrane life and consistent operation in challenging water treatment environments.

Compared to mainstream imported membranes, the NF98 series achieves over twice the flux while reducing operating pressure by more than 50%. With these advantages, the NF98 membranes not only outperform but can also perfectly replace NF270, XC-N, DL, DK, and other conventional TFC nanofiltration membranes in both municipal and industrial water treatment systems.

Key Advantages of NF98 Nanofiltration Membranes

Super-Hydrophilic Surface & Long Service Life
The NF98 membranes feature an ultra-hydrophilic surface, which enhances anti-fouling properties, reduces scaling, and extends operational lifetime, making them highly reliable for continuous water treatment processes.

Higher Flux & Lower Energy Consumption
On average, NF98 membranes deliver 30% higher flux than traditional TFC membranes. In certain models, the flux can be up to twice as high, allowing operators to significantly lower energy consumption and reduce overall operating costs.

Superior Salt & Contaminant Removal

Achieves over 98% removal rate for high-priced salts such as magnesium sulfate, iron, and other heavy metals.

Allows controlled passage of monovalent salts, making it ideal for applications requiring precise ionic separation.

Demonstrates high rejection of organic compounds including pesticides, herbicides, antibiotics, and THM precursors, ensuring safe and clean water quality.

Why Choose NF98 for Advanced Water Treatment?

The NF98 series offers exceptional efficiency, reliability, and selectivity for industries and municipalities that demand high-performance water treatment membranes. With its ability to deliver higher flux, lower operating pressure, and excellent contaminant removal, the NF98 membrane sets a new standard for sustainable and cost-effective nanofiltration solutions.

1. Under controlled test conditions, our water yield and desalination rates were meticulously measured using: 2000 ppm MgSO4, 70 psi (0.48 MPa), 77°F (25°C), 15% recovery; 2000 ppm NaCl, 70 psi (0.48 MPa), 77°F (25°C), 15% recovery

2. The water yield variation range is +/- 15%, ensuring consistent performance across different conditions

3.  The HF, SP, Pro, and SPEC series cater to high throughput, salt separation, high rejection, and bespoke nanofiltration needs, respectively. (Please consult our pre-sales engineers for more details.)
