NF98 Series Nanofiltration Membrane ElementThe NF98 series features a proprietary multilayer composite membrane with nano-level, ultra-thin hydrophilic coating technology. This advanced engineering delivers exceptional anti-fouling performance while achieving flux rates twice as high as leading international brands, and operating at 50% lower pressure. Its impressive performance allows it to replace traditional TFC membranes like NF270, XC-N, DL, DK, and more.
1. The NF98 membrane boasts a super hydrophilic surface, ensuring outstanding anti-fouling capabilities and prolonged lifespan.Nanofiltration is a specialized membrane process that rejects dissolved solutes approximately 1 nanometer (10 Angstroms) in size, hence the term 'nanofiltration.'
In terms of solute size and weight rejection, nanofiltration operates in the realm betweenreverse osmosis (RO) and ultrafiltration (UF). : It effectively rejects organic molecules with molecular weights over 200 - 400. Nanofiltration membranes can efficiently block contaminants such as:
Typical applications of nanofiltration membrane systems include:

The water yield and desalination rates are derived from rigorous standard test conditions: 2000 ppm MgSO4, 70 psi (0.48 MPa), 77 °F (25 °C), 15% recovery, and 2000 ppm NaCl, 70 psi (0.48 MPa), 77 °F (25 °C), 15% recovery.
2. The water yield variation range is +/- 15%, ensuring consistent performance.
3. The F34 model features a fiberglass-wrapped case with a mesh thickness of 34 mil. Additional shells, meshes, and components are available for customization. The labels HF, SP, Pro, and SPEC signify high throughput, salt separation, high rejection, and customized series of nanofiltration membranes, respectively.
