Multilayer Composite Membrane NF8040 And 4040
NF98 Nanofiltration Membrane – Advanced Technology for Superior Water Treatment
The NF98 series nanofiltration membrane element is engineered with proprietary multilayer composite technology and an ultra-thin hydrophilic coating applied through nano-level regulation. This innovation delivers outstanding anti-fouling performance and ensures superior long-term stability in water treatment applications. With performance that completely surpasses conventional NF270, XC-N, DL, and DK membranes, the NF98 membrane not only outperforms traditional thin-film composite (TFC) membranes but also provides a cost-effective replacement solution.
Compared to standard imported membranes, the NF98 nanofiltration membrane offers over twice the flux capacity while operating at 50% lower pressure, making it one of the most energy-efficient choices in modern water treatment systems.
Key Advantages of NF98 Nanofiltration Membranes
Exceptional Durability & Anti-Fouling Surface
The NF98 features an ultra-hydrophilic surface layer that resists organic fouling and scaling, significantly extending membrane life and ensuring consistent water quality.
Higher Flux with Lower Energy Consumption
The NF98 nanofiltration membrane achieves flux levels that are typically 30% higher than conventional TFC membranes, and in some cases, performance is double that of competing imports. With reduced operating pressure by more than 50%, it provides exceptional energy savings and lower overall operating costs.
Superior Contaminant Rejection
Removes >98% of divalent and multivalent salts, including iron, magnesium sulfate, and heavy metals.
Achieves high rejection of organic pollutants such as antibiotics, herbicides, insecticides, and THM (trihalomethane) precursors.
Ensures reliable separation while maintaining strong monovalent salt rejection, making it ideal for advanced water treatment requirements.
Why Choose NF98 for Your Water Treatment Needs?
The NF98 membrane is specifically designed for industrial and municipal water treatment plants, offering unmatched performance, durability, and cost efficiency. Its ability to combine high flux, low operating pressure, and superior contaminant rejection makes it a next-generation solution for facilities seeking reliable water purification with reduced energy consumption.
