Seawater RO

Overview
LG Chem's thin-film nanocomposite (TFN) membranes has lower water treatment costs by improving energy efficiency and productivity. LG Chem's line of NanoH2OTM RO Membrane features benign nanomaterials incorporated into the thin-film polyamide layer of a composite membrane. This innovative patented technology significantly increases membrane permeability while matching best-in-class salt rejection.
 
"ES" : Energy Saving Membranes
Well suited for low temperature seawater or two-pass system.
"GR", "SR", "R": High Rejection Membranes
Well suited for high quality permeate requirements or reducing size of second pass

Configuration: 8-inch spiral wound
Membrane Polymer: Thin-film nanocomposite (TFN) polyamide
