NF98 Series Nanofiltration Membrane ElementIntroducing our NF98 series nanofiltration membrane element, designed with a proprietary multilayer composite membrane and nano-level, ultra-thin hydrophilic coating technology. Our advanced design offers exceptional anti-fouling performance, with flux rates that are double those of leading international brands, and operating pressure that is at least 50% lower. This comprehensive performance enables the NF98 to effectively replace traditional TFC membranes such as NF270, XC-N, DL, DK, and more.
Key Features:
Nanofiltration is a specialized membrane process that rejects dissolved solutes in the size range of approximately 1 nanometer (10 Angstroms), hence the name 'nanofiltration.'
Nanofiltration operates in the size and weight range of solutes betweenreverse osmosis (RO) and ultrafiltration (UF). : Organic molecules with molecular weights between 200 - 400 are effectively rejected by nanofiltration membranes. These membranes can efficiently remove various contaminants such as:
Typical applications of nanofiltration membrane systems include:

Water yield and desalination rates were determined under the following precise 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 has a potential variation range of ±15%.
3. The F34 model features a fiberglass-wrapped casing with a mesh thickness of 34 mil. Additional shells, meshes, and components are available for customization. The HF, SP, Pro, and SPEC notations denote high throughput, salt separation, high rejection, and customized series of nanofiltration membranes, respectively.
