DF membrane


Ultra-low pressure selective Nano filtration membrane (DF) products, is a completely independent intellectual property of innovative products, in the international initiative.

The pore diameter of DF film is 1 nm, which is equivalent to 1/500,000 of the hair filament and 1/100 of the ultrafiltration membrane.

It can effectively remove heavy metal ions, dissolved organic matter, colloids, bacteria and viruses, and retain small molecules of organic matter that are beneficial to the body and low-priced inorganic salt.

product feature

Uniform performance: adopt advanced production equipment and film making technology, the component performance is uniform and stable.

Low operating pressure: compared with traditional NF and reverse osmosis membrane, it has the characteristics of low operating pressure and operating cost.

High water yield: compared with traditional NF and reverse osmosis membranes, high water yield under the same operating pressure.

Good interception effect: the interception molecular weight of 100~500 Daltons can effectively trap organic pollutants and heavy metal ions.

Good anti-pollution performance: smooth surface, good hydrophobicity, close to electrical neutral, good anti-pollution ability.

Moderate desalination: can retain the minerals that the human body needs in water, to achieve a healthy drinking water.

High COD removal rate: the national standard grade A effluent can be used as the source of water, greatly reducing COD, and the water quality of production reaches above the surface level II.
