LG Chem NanoH brackish water, reverse osmosis and seawater membranes2O ™ lower water treatment costs by improving energy efficiency and productivity. These thin film nanocomposite (TFN) membranes are made up of beneficial nanomaterials that have been incorporated into the polyamide layer. This proprietary technology by LG significantly increases the permeability of the membrane making it comparable to the best in class in terms of rejection of salts.

  • Excellent flow and rejection of salts
  • Ideal for low energy applications
  • Easy to retrofit existing reverse osmosis plants
