Daltonen Focusing on Separating Membrane Products and Fluid Technology Services.
DA-NF100-400
Product Introduction
The Daltonen Membrane NF100 nanofiltration membrane element can achieve high water yield while exhibiting excellent monovalent and divalent salt removal performance, effectively removing high organic compounds such as insecticides, herbicides, and THM precursors. In the process of water treatment, while reducing the hardness of the water, it can effectively remove toxic and harmful substances in the water, remove turbidity, chromaticity, and organic matter, and also recover special high valence salts and small molecule organic matter. The NF100 series nanofiltration membrane components come in two sizes: 4 "and 8", suitable for papermaking, printing and dyeing industries, and municipal water treatment systems.
· Excellent removal performance of monovalent and divalent salts
· Suitable for removing TOC and THM precursors
· A system that removes salts and operates with low energy consumption under ultra-low pressure conditions
