NF-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 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.
34mil Feed channel spacer is adopted toreduce the pressure drop and enhances theanti-fouling and ease of ability of membraneelement.
It is widely used in the fields of zero-liquid discharge of wastewater,chloralkali denitration, lithium extractionfrom Salt Lake,material decolorization.materialseparation and soon.
