NF98 Series Nanofiltration Membrane ElementThe NF98 series employs a proprietary multilayer composite membrane with an ultra-thin, nano-level hydrophilic coating. It boasts exceptional anti-fouling properties and offers a flux rate that is twice that of leading international brands. Furthermore, it operates at a pressure that is at least 50% lower. Its superior performance allows it to replace traditional TFC membranes such as NF270, XC-N, DL, and DK.
1. The NF98 membrane features a highly hydrophilic surface, providing outstanding anti-fouling performance and prolonged lifespan.Nanofiltration is a specialized membrane process that rejects dissolved solutes approximately in the size range of 1 nanometer (10 Angstroms), hence the term 'nanofiltration.'
Regarding the size and weight of solutes that nanofiltration membranes reject, NF operates in the realm betweenreverse osmosis (RO) and ultrafiltration (UF) : Organic molecules with molecular weights greater than 200-400 are rejected. Nanofiltration membranes can effectively reject various contaminants, including:
Typical applications of nanofiltration membrane systems include:
