Nanofiltration membrane el ement
Category：
Product features
1、It is aplicable to brine purfication, heavy metal removal, desalination and concentration of materials, recovery of sodium chloride solution and removal of COD in sewage. With a molecualr weight cut-off of about 200 dalton, it has a high rejection rate for most divalent and multivalentions, and transmits monovalent salts at the same time.
2、34mil Feed channel spacer is adopted to reduce the pressure drop and enhances the anti-fouling and ease of ability of membrane element.
3、It is widely used in the fields of zero-liquid discharge of wastewater,chlorakali denitration, lithium extraction from Salt Lake，material decolorization,material separation and soon.
