Low Working Pressure High Flux Nanofiltration(NF) Membrane Element-NF2-4040
Low Working Pressure High Flux Nanofiltration(NF) Membrane Element-NF2-4040
1. Pore size control: The pore size of the nanofiltration membrane is about 1-2 nanometers, which enables it to selectively allow certain solvent molecules and small molecular solutes to pass through, while retaining larger molecules and ions.
2. Wide application: Nanofiltration membranes are widely used in water treatment, food processing, pharmaceuticals, chemical industry and other fields. For example, it can be used to remove organic matter and chromaticity from surface water, remove hardness from groundwater, partially remove soluble salts, concentrate juices, and separate useful substances in medicines.
3. Low operating pressure: The operating pressure of the nanofiltration membrane is low, usually around several atmospheres, which makes it more economical and efficient in industrial applications.
4. Strong material selectivity: The nanofiltration membrane has different retention properties for monovalent and divalent ions and small molecular organic matter, which makes it more flexible in different industrial applications.
5. Environmental protection and energy saving: The concentration and purification process of the nanofiltration membrane is carried out at room temperature, without phase change and chemical reaction, and is particularly suitable for the treatment of heat-sensitive substances. In addition, the equipment has a compact structure, small footprint, low energy consumption, easy operation, can realize automated operation, good stability and easy maintenance.
It is applicable to the desalination of direct drinking water, spring water, boiler water, also desalination and decolorization of wastewater with high salt concentration.
