Thin-film membranes are widely used in water treatment processes as a means of removing contaminants and purifying water from a broad range of sources. LG Chem develops and manufactures reverse osmosis (RO) membranes that are widely used in various applications ranging from seawater desalination to waste water reuse. In May 2014, LG Chem acquired NanoH2O, a US-based RO membrane manufacturer known for its innovative thin-film nanocomposite membrane technology that dramatically improves membrane efficiency and productivity. This unique technology, combined with LG Chem’s experience in roll-to-roll coating, excellence in chemical and polymer manufacturing, and world-class research & development will propel the growth of its NanoH2O™ line of reverse osmosis membranes.
