NF98 Series Nanofiltration Membrane ElementThe NF98 series nanofiltration membrane element incorporates a proprietary multilayer composite membrane with a nano-level, ultra-thin hydrophilic coating technology. This advanced design ensures exceptional anti-fouling performance and doubles the flux compared to leading international brands, while operating at 50% lower pressure. Its superior performance makes it a versatile replacement for traditional TFC membranes like NF270, XC-N, DL, and DK.
Key Features:
Nanofiltration is a specialized membrane process designed to reject dissolved solutes approximately 1 nanometer (10 Angstroms) in size, hence the term 'nanofiltration.'
Nanofiltration operates betweenreverse osmosis (RO) and ultrafiltration (UF) :It effectively rejects organic molecules with molecular weights between 200 and 400, filtering out contaminants such as:
Typical applications of nanofiltration membrane systems include:
