Daltonen Focusing on Separating Membrane Products and Fluid Technology Services.
DA-NF600-400
Product Introduction
The Daltonen Membrane NF600 nanofiltration membrane adopts the latest membrane component manufacturing technology to minimize filtration dead corners and bypasses, and has the characteristics of high flux and high desalination. It has high retention for divalent ions and good retention for monovalent ions, achieving high water yield while effectively retaining organic compounds with molecular weights of 300-600 (Dalton) or above, and also has excellent decolorization performance. The NF600 series nanofiltration membrane components come in two sizes: 4 "and 8", suitable for various fields such as reclaimed water reuse and municipal water use
· With extremely high flux and high removal rate
· Suitable for high salt water treatment
· Achieve high water yield while maintaining moderate removal performance
