NF98 series nanofiltration membrane elementThe NF98 series nanofiltration membrane adopts a proprietary multilayer composite membrane, featuring nano-level, ultra-thin hydrophilic coating technology that offers outstanding anti-fouling performance. With flux rates that are twice as high as leading international brands and operating pressures at least 50% lower, this membrane outperforms traditional TFC membranes such as NF270, XC-N, DL, and DK.
1. The NF98 membrane boasts a super hydrophilic surface, ensuring excellent anti-fouling performance and an extended lifespan.Nanofiltration is a specialized membrane process that rejects dissolved solutes roughly sized around 1 nanometer (10 Angstroms), thus the term 'nanofiltration.'
In terms of solute size and weight, nanofiltration operates in the intermediate range betweenreverse osmosis (RO) and ultrafiltration (UF). : Organic molecules with molecular weights greater than 200-400 are effectively rejected. Nanofiltration membranes can efficiently filter out various contaminants, including:
Typical applications of nanofiltration membrane systems include:
