Core Functions Of NF water Treatment Equipment

Nanofiltration system

Nanofiltration is a pressure-driven membrane separation technology between reverse osmosis and ultrafiltration. The pore size of the nanofiltration membrane is between 1 and 100 nanometers. The technical principle is similar to mechanical sieving, and molecular-level substances are screened according to the size of the micropores. It is a derivative product of reverse osmosis membrane, also known as loose reverse osmosis membrane, but the operating pressure is lower than that of reverse osmosis. It has a high removal rate for divalent or multivalent ions and organic substances with a molecular weight between 200 and 500 in the liquid.

Comprehensive characteristics and advantages :

① Pore Size Characteristics: The pore size of the nanofiltration membrane is between 1 nanometer and 2 nanometers. It can effectively remove most organic matter, microorganisms (such as bacteria and viruses), some dissolved salts and some specific ions in the water, such as divalent ions.

② Separation Principle: The nanofiltration membrane's separation layer of polyelectrolytes has electrostatic ion interactions and retains inorganic salts. Its separation process lacks chemical reactions, heating, phase changes, and doesn't affect separated substances' bioactivity, flavor, and aroma.

③ Ultra-low Pressure And Large Fux: The nanofiltration membrane can work at ultra-low pressure (such as 0.1Mpa) and maintain a large flux, which makes its energy consumption lower and the operating cost is correspondingly reduced.

④ Controllability And Fiexibility: Nanofiltration membrane technology can selectively intercept molecules or ions of different sizes and charge states by adjusting the pore size and charge properties of the membrane.

⑤Economical And Efficient: Although the initial investment in nanofiltration membrane technology may be relatively high, considering the long-term operating cost savings (such as energy consumption, chemical use and maintenance costs), nanofiltration membrane technology often shows better economic efficiency throughout the life cycle.

⑥ Improve Water Quality Safety: Nanofiltration membranes can significantly reduce the organic content in raw water and reduce the risk of generating disinfection by-products (such as trihalomethanes and haloacetic acids) during subsequent disinfection, thereby improving the safety of drinking water.
