NF98 Series Nanofiltration Membrane ElementOur NF98 series adopts a proprietary multi-layer composite membrane featuring nano-level, ultra-thin hydrophilic coating technology. This innovation ensures superior anti-fouling performance, with flux rates that are twice as high as those of leading international brands, while operating pressures are reduced by at least 50%. This exceptional performance allows the NF98 to seamlessly replace traditional TFC membranes such as NF270, XC-N, DL, DK, and more.
1. The NF98 membrane boasts an incredibly hydrophilic surface, delivering excellent anti-fouling performance and extended longevity.Nanofiltration is a specialized membrane process that rejects dissolved solutes in the size range of approximately 1 nanometer (10 Angstroms). This level of filtration is termed 'nanofiltration.'
Regarding the size and weight of solutes rejected by nanofiltration membranes, NF operates in the intermediate range betweenreverse osmosis (RO) and ultrafiltration (UF). : Nanofiltration membranes effectively reject organic molecules with molecular weights greater than 200-400, among other contaminants:
Typical applications of nanofiltration membrane systems include:

Water yield and desalination rates were 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. The water yield may vary within a range of +/-15%.
3. The F34 model features a fiberglass-wrapped case with a mesh thickness of 34 mil. Optional shells, meshes, and components are available. The HF, SP, Pro, and SPEC series denote high throughput, salt separation, high rejection, and customized nanofiltration membranes, respectively.
