NF98 Series Nanofiltration Membrane ElementThis advanced NF98 membrane element incorporates a proprietary multilayer composite membrane with nano-level, ultra-thin hydrophilic coating technology. It delivers outstanding anti-fouling performance and boasts a flux that is twice as high as leading international brands, while operating at least 50% lower pressure. Its comprehensive performance makes it an ideal replacement for traditional TFC membranes such as NF270, XC-N, DL, DK, and others.
Key Features:
Nanofiltration is a specialized membrane filtration process that rejects dissolved solutes within the approximate size range of 1 nanometer (10 Angstroms), hence the name 'nanofiltration.'
Regarding solute size and weight, nanofiltration operates in the intermediate range betweenreverse osmosis (RO) and ultrafiltration (UF) :It effectively rejects organic molecules with molecular weights greater than 200 - 400. Nanofiltration membranes can proficiently filter out various contaminants, including:
Typical applications of nanofiltration membrane systems include:
