NF Multilayer Composite Membrane 8040 And 4040

NF98 Nanofiltration Membrane – Next-Generation Solution for Advanced Water Treatment

The NF98 series nanofiltration membrane element is designed with a proprietary multilayer composite structure and an ultra-thin hydrophilic coating engineered through nano-level regulation. This cutting-edge design provides superior anti-fouling capability, ensuring stable long-term operation in demanding water treatment environments.

Compared to mainstream imported products, the NF98 nanofiltration membrane delivers more than twice the flux while operating at over 50% lower pressure, significantly reducing energy consumption and operating costs. Its overall performance far surpasses traditional TFC nanofiltration membranes such as NF270, XC-N, DL, and DK, making it a reliable and cost-effective replacement for advanced water treatment systems.

Key Features and Benefits

Ultra-Hydrophilic Surface for Superior Anti-Fouling
The NF98 membrane surface is super hydrophilic, which greatly reduces scaling and organic fouling. This ensures excellent durability, extended duct life, and stable long-term operation in industrial and municipal water treatment applications.

High Flux with Reduced Energy Demand
On average, the membrane flux of NF98 is more than 30% higher than conventional TFC membranes, with certain models reaching up to twice the flux. At the same time, its operating pressure is reduced by more than 50%, enabling significant energy savings without compromising water purity.

Exceptional Contaminant Rejection

>98% removal of divalent and multivalent salts, including magnesium sulfate, iron, and heavy metals.

High efficiency in separating organic contaminants such as pesticides, herbicides, antibiotics, and THM precursors.

Selective passage of monovalent salts, making it suitable for applications requiring partial softening while maintaining essential minerals.

Why Choose NF98 Nanofiltration Membranes for Water Treatment?

The NF98 series provides unmatched performance, long service life, and lower energy costs, making it the ideal choice for industries, municipalities, and facilities requiring high-efficiency water treatment. By combining higher flux, lower operating pressure, and superior contaminant rejection, NF98 sets a new standard for reliable, sustainable, and cost-effective water purification.
