Nanofiltration membrane element TN family
Product characteristics
Suitable for salt water purification, heavy metal removal, desalination and concentration of materials, recovery of sodium chloride solution, and removal of COD from wastewater. The retention molecular weight is about 200 Daltons, and it has a high retention rate for many divalent and multivalent ions, while passing through monovalent salts.
