NF98 Series Nanofiltration Membrane ElementThis advanced membrane element utilizes a proprietary multilayer composite membrane featuring nano-level, ultra-thin hydrophilic coating technology. It offers exceptional anti-fouling performance, delivering a flux rate twice as high as leading international brands, while operating at 50% lower pressure. Its comprehensive performance makes it an ideal replacement for traditional TFC membranes, including NF270, XC-N, DL, DK, and more.
Key Features:
Nanofiltration is a specialized membrane process that rejects dissolved solutes within the size range of approximately 1 nanometer (10 Angstroms), hence the term 'nanofiltration.'
In terms of solute size and weight, nanofiltration membranes operate betweenreverse osmosis (RO) and ultrafiltration (UF). Organic molecules with molecular weights greater than 200-400 are rejected. Nanofiltration membranes effectively filter out several contaminants, including:
Typical applications of nanofiltration membrane systems include:

Under controlled test conditions, our water yield and desalination rates were meticulously measured using: 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 variation range is +/- 15%, ensuring consistent performance across different conditions.
3. The F34 model features a robust fiberglass wrapping with a mesh thickness of 34 mil. Additional shells, meshes, and components are available for customization. The HF, SP, Pro, and SPEC series cater to high throughput, salt separation, high rejection, and bespoke nanofiltration needs, respectively. (Please consult our pre-sales engineers for more details.)
