NanoH2O is a reverse osmosis (RO) membrane manufacturer known for its innovative thin-film nanocomposite membrane technology that lowers the cost of desalination. Based on breakthrough nanostructured materials and industry-proven polymer technology, NanoH2O's QuantumFlux membranes dramatically improve desalination energy efficiency and productivity. The result is a wide array of advantageous membrane characteristics including improved throughput at requisite salt and contaminant rejection levels, passive and active fouling resistance, and the flexibility to address specific water chemistries. Graduated in 2009 NanoH2O was acquired by LG Chem in 2014 for $200M.
