High divalent salt retention, exceptional monovalent salt passage, and an exceptionally high flux and rejection rate define SM NF 500 series NF membranes. It attains high flux while providing a moderate rate of organic matter removal. Organic molecules with a cut-off molecular weight between 300 and 500 D can be efficiently retained by it. It also provides outstanding decolorization. The SM NF500 series uses the most recent advancements in membrane manufacturing technology to reduce bypasses and dead spots during the filtration process. 

Remarks of NF Membrane
  1. The individual element's permeate flow may differ by up to 15% from the specified value.
  2. Guaranteed active membrane area within ±4%.
  3. Stabilized salt rejection can usually be attained within 24-48 hours of continuous use, contingent on the properties of the feedwater and the operating environment.
