NF98 Series Nanofiltration Membrane ElementOur NF98 series nanofiltration membrane element, crafted exclusively with a proprietary multilayer composite membrane and nano-level ultra-thin hydrophilic coating technology, offers unparalleled anti-fouling capabilities. Delivering flux rates that are twice as high as those of leading international brands, it operates with at least 50% lower pressure. This advanced performance allows it to seamlessly replace traditional TFC membranes like NF270, XC-N, DL, DK, and more.
Key Features:
Nanofiltration is a specialized membrane process that rejects dissolved solutes approximately within the size range of 1 nanometer (10 Angstroms), hence known as 'nanofiltration.'
With respect to 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 effectively rejected by nanofiltration membranes. They can efficiently filter out contaminants such as:
Typical applications of nanofiltration membrane systems include:
