LG NanoH2O, Inc.

LG NanoH2O designs, develops, manufactures and markets reverse osmosis (RO) mem­branes that lower the cost of desalination. Based on breakthrough nanostructured materials and industry-proven polymer technology, LG NanoH2O’s RO membranes dramatically improve desalination energy efficiency and productivity. LG NanoH2O seawater reverse osmosis (SWRO) membranes, Standard 61 certified by NSF International for the production of drinking water, deliver the highest flux and the highest salt rejection of any SWRO membrane on the market. These membranes are available in standard 8-inch (20 cm) diameter elements that fit easily into new and existing desalination plants, purifying water from a broad range of sources with improved productivity and water quality. LG NanoH2O is headquartered in Los Angeles, California, and is a wholly owned company of LG Chem, Ltd.
