NF98 Series Nanofiltration Membrane ElementThe NF98 series employs our proprietary multilayer composite membrane combined with nano-level, ultra-thin hydrophilic coating technology. This unique combination delivers superior anti-fouling performance while achieving flux rates that are twice as high as leading international brands, all while operating at pressures at least 50% lower. Its comprehensive performance makes it a robust replacement for traditional TFC membranes like NF270, XC-N, DL, and DK.
Key Features:
Nanofiltration is a specialized membrane process that filters dissolved solutes in the size range of approximately 1 nanometer (10 Angstroms), hence the name 'nanofiltration.'
In terms of solute size and weight rejection, nanofiltration operates in the niche betweenreverse osmosis (RO) and ultrafiltration (UF) :Organic molecules with molecular weights greater than 200-400 are effectively rejected by nanofiltration membranes, making them highly efficient against various contaminants such as:
Typical applications of nanofiltration membrane systems include:

Feed spacer thickness (mil) |

Water yield and desalination rates are based on the following standard test conditions: 2000 ppm MgSO4, 70 psi (0.48 MPa), 77°F (25°C), 15% recovery, 2000 ppm NaCl, 70 psi (0.48 MPa), 77°F (25°C), 15% recovery.
2. Variation in water yield is within a +/-15% range.
3. F34 is a fiberglass-wrapped case with a mesh thickness of 34 mil. Additional shells, meshes, and components are available as options. The HF, SP, Pro, and SPEC letters denote high throughput, salt separation, high rejection, and customized series of nanofiltration membranes respectively.
