TN series – nanofiltration RO membrane element (TN-8040-400)
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.

Product Description
Introducing our revolutionary new product, designed to meet the growing demand for sustainable and efficient solutions for water treatment - our advanced membrane technology.
Our membrane technology is highly versatile and can be applied to a range of water treatment applications, including brine purification, heavy metal removal, desalination, and concentration of materials. It is also highly effective in the recovery of sodium chloride solution and removal of COD in sewage.
What makes our technology stand out is its unique molecular weight of around 200 daltons. This gives it a high rejection rate for most divalent and multivalent ions, which are often the most difficult to remove from water. At the same time, our membrane technology is highly selective and transmits monovalent salts, which are essential for many industrial and agricultural applications.
