TN series – nanofiltration RO membrane element (TN-4040)
Product Features
It is applicable to brine purification, heavy metal removal, desalination and concentration of materials, recovery of sodium chloride solution and removal of COD in sewage. With a molecular weight of about 200 daltons, it has a high rejection rate for most divalent and multivalentions, and transmits monovalent salts at the same time.
34mil Feed channel spacer is adopted to reduce the pressure drop and enhances the anti pollution and anti cleaning ability of membrane element.
It is widely used in the fields of zero discharge of wastewater, chloralkali denitration, lithium extraction from Salt Lake, material decolorization，material separation and soon.
