NF98 Series Nanofiltration Membrane ElementThis element adopts a proprietary multilayer composite membrane with nano-level, ultra-thin hydrophilic coating technology. It offers exceptional anti-fouling performance and boasts a flux rate twice that of leading international brands, all while operating at least 50% lower pressure. Its comprehensive performance is so advanced that it can replace traditional TFC membranes like NF270, XC-N, DL, DK, and others.
Key Features:
Nanofiltration is a specialized membrane process that rejects dissolved solutes approximately 1 nanometer (10 Angstroms) in size-hence the term "nanofiltration."
Regarding the size and weight of solutes that nanofiltration membranes reject, NF operates betweenreverse osmosis (RO) and ultrafiltration (UF) : Organic molecules with molecular weights between 200 - 400 are effectively rejected. Nanofiltration membranes can successfully reject various contaminants, including:
Typical applications of nanofiltration membrane systems include:

Our water yield and desalination rates are meticulously tested under these standard conditions: 2000 ppm MgSO4, 70 psi (0.48 MPa), 77 °F (25 °C), with a 15% recovery rate; 2000 ppm NaCl, 70 psi (0.48 MPa), 77 °F (25 °C), also at a 15% recovery rate.
2. The variation range of water yield is within +/-15%, ensuring consistent performance.
3. The F34 model features a robust fiberglass-wrapped case with a 34-mil mesh thickness. We offer additional shells, meshes, and components to suit your needs. The HF, SP, Pro, and SPEC labels indicate high throughput, salt separation, high rejection, and customized series of nanofiltration membranes, respectively. (For more details, please consult our pre-sales engineers).
