LG Chem expands reverse-osmosis membrane capacity at Cheongju

LG Chem announced an expansion of reverse-osmosis membrane production at its Cheongju site in 2022, adding capacity for seawater desalination elements as the company pressed into large international tenders.

LG Chem's water business, built on thin-film nanocomposite membrane technology acquired with NanoH2O in 2014, has become one of the handful of suppliers regularly specified in Gulf mega-projects alongside Toray, Nitto/Hydranautics and DuPont's FilmTec — an increasingly Asian-led supply base for the world's fastest-growing treatment segment.
