Equipment overview:

Nanofiltration (NF) is a membrane separation technology between ultrafiltration and reverse osmosis. Its interception molecular weight is in the range of 80-2000, the aperture is about 1 nanometer, suitable for the separation of ions greater than 1 nanometer, so it is called nanofiltration. The nanofiltration process can be used at room temperature, no phase change, no chemical reaction, no destruction of biological activity, can effectively retain the bivalent, molecular weight of more than 200 organic molecules, and make most of the monovalent inorganic salt ions through, can separate similar proteins and amino acids, to achieve the separation of high molecular weight and low molecular weight organic matter.

Main features:

1. Compared with ultrafiltration, it has the ability to intercept medium and low molecules.

2. Compared with reverse osmosis, it has low operating pressure and large water flux.

3. High efficiency, low energy consumption, economical operation cost.

4. Compact and reasonable equipment structure, convenient operation and maintenance, small footprint, save investment.

5. It can realize automatic operation, simple installation, debugging and operation, and stable performance of control components.

Operating conditions:

1. Operating pressure: ≤ 1.50Mpa

2. Inlet water SDI: ≤5

3. Inlet water temperature: 5℃-50℃

4. PH value: 2-11

5. Water hardness: ≤0.03mmol/L

Scope of application:

Based on the superior characteristics of nanofiltration separation technology, it has shown broad application prospects in many fields such as ultrapure water preparation, pharmacy, biology, chemical industry, food, environmental protection, metallurgy industry and so on.
