Short Description:

lt 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 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.
