NF98 Series Nanofiltration Membrane ElementThe NF98 Series adopts a proprietary multilayer composite membrane featuring nano-level, ultra-thin hydrophilic coating technology, ensuring excellent anti-fouling performance. These membranes boast a flux that is twice as high as leading international brands and operate at 50% lower pressure. Their comprehensive performance allows them to replace traditional TFC membranes such as NF270, XC-N, DL, DK, and more.
1. The NF98 membrane boasts a super hydrophilic surface, superior anti-fouling performance, and an extended lifespan.Nanofiltration refers to a specialized membrane process that rejects dissolved solutes in the size range of approximately 1 nanometer (10 Angstroms)-hence the term "nanofiltration."
In terms of the size and weight of solutes rejected, nanofiltration operates in the realm betweenreverse osmosis (RO) and ultrafiltration (UF) : Nanofiltration membranes effectively reject organic molecules with molecular weights greater than 200-400, including:
Typical applications of nanofiltration membrane systems include:
