NanoH2O

NanoH2O was founded in 2005 at UCLA in Los Angeles, California, developing nanocomposite reverse osmosis (RO) membrane technology that lowers the cost of desalination and industrial water treatment. The company's QuantumFlux membranes deliver higher water flux at lower energy consumption than conventional RO membranes, and the technology won the Global Water Award for World's Innovation of the Year in 2008. NanoH2O was acquired by LG Chem in April 2014, becoming the foundation of LG Water Solutions, and the brand was later restored as NanoH2O in December 2025 as it continued to scale its desalination and water-reuse membrane portfolio (QuantumFlux, QuantumPure, NF9) into large seawater and brackish-water projects worldwide.
