BDX4040N and BDX8040N series of spiral nano filtration membrane adopted polyamide. They have moderate desalination rate and has relatively high desalination rate to remove macromolecule, multiple valence ion and especially noxious TOC substances in water, such as pesticide, weed-killer and THM predecessor.BDX4040N and BDX8040N series are excellent in the water softening and organism removal. They are applicable to drinking water, municipal engineering and etc.
The trades to which Nano filtration membrane technique is suitable:
(1) Removal of two valet ion and organics by softening.
(2) Recovery of dyeing.
(3) Separation and refinement of oligosaccharide, concentration of high strong fruit juice.
(4) Separation of peptide and amino acid ,concentration and purification of antibiotics.
(5) Concentration of milk and whey protein.
(6) Comprehensive utilization of agricultural products.
