HID™ Nanofiltration Membranes

Nanofiltration (NF) Membrane technology is a membrane separation technology between ultrafiltration and reverses osmosis. Its molecular weight cut-off is in the range of 80-1000, and the pore size is a few nanometers, so it is called nanofiltration. For a long time in the past, nanofiltration membranes have been called Low-Pressure Reverse Osmosis Membranes, or Loose Reverse Osmosis membranes. Now, nanofiltration technology has been separated from reverse osmosis technology and has become an independent separation technology between ultrafiltration and reverse osmosis technology. It has been widely used in seawater desalination, ultrapure water manufacturing, food industry, environmental protection, etc. Many fields have become an important branch of membrane separation technology.

HID has 5 types of nanofiltration membranes for customers to choose from, the models are: HNF-8040HF, HNF-8040HR, HNF-4040HF, HNF-4040HR, HNF-75GPD

What are the characteristics of HID™ Nanofiltration Membranes?

1. The concentration and purification process is carried out at room temperature, with no phase change, no chemical reaction, no other impurities, and no decomposition and denaturation of the product, especially suitable for heat-sensitive substances.
2. It can remove the salt of the product, reduce the ash content of the product, and improve the purity of the product. Compared with solvent desalination, not only the product quality is better, but the yield can also be improved.
3. The process has high yield and low loss
4. It can recover effective substances such as acid, alkali, and alcohol in the solution to realize the recycling of resources
5. The equipment has a compact structure, small footprint, and low energy consumption
6. Simple operation, automatic operation, good stability, and easy maintenance

HID™ Nanofiltration membranes have a wide range of applications, mainly including the following aspects:

1. In addition to the hardness of groundwater
2. Remove organic matter and chroma of surface water
3. Oil-water separation
4. Ethylene glycol recovery
5. Copper sulfate recovery
6. Separation and concentration of organic and inorganic liquids
7. Dye purification, concentration and desalination
8. Separation and concentration of natural medicine
9. Concentration of fermentation broth
