NF98 Series Nanofiltration Membrane ElementAdopting a proprietary multilayer composite membrane with nano-level, ultra-thin hydrophilic coating technology, the NF98 series boasts exceptional anti-fouling performance. It achieves flux rates twice as high as leading international brands while operating at 50% lower pressure. Its superior capabilities make it a versatile replacement for traditional TFC membranes, such as NF270, XC-N, DL, and DK.
Key Features:
Nanofiltration is a specialized membrane process that rejects dissolved solutes approximately 1 nanometer in size (10 Angstroms), hence the name 'nanofiltration.'
Regarding the size and weight of solutes that nanofiltration membranes reject, NF operates between:reverse osmosis (RO) and ultrafiltration (UF) :Organic molecules with molecular weights greater than 200 - 400 are rejected. Nanofiltration membranes can effectively reject, among other contaminants:
Typical applications of nanofiltration membrane systems include:

Our water yield and desalination rates are derived from rigorous standard test conditions: 2000 ppm MgSO4 at 70 psi (0.48 MPa) and 77°F (25°C), with a 15% recovery rate. Similarly, for NaCl, the conditions are 2000 ppm at 70 psi (0.48 MPa) and 77°F (25°C), maintaining a 15% recovery rate.
2. The water yield variation range stands at +/- 15%, ensuring reliable performance.
3. The F34 model boasts a robust fiberglass wrapped case with a mesh thickness of 34 mil. For added versatility, additional shells, meshes, and components are available. The HF, SP, PRO, and SPEC series denote high throughput, superior salt separation, high rejection, and tailor-made nanofiltration membranes, respectively.
