LG SW 4040 R


LG Chem’s NanoH2O™ seawater RO membranes - incorporated with innovative Thin Film Nanocomposite (TFN)
technology, deliver industry-leading salt rejection and 20% more flow than the membranes manufactured from
conventional technologies. Our seawater RO membranes significantly reduce the cost of desalination while delivering
superior water quality. In LG Chem, we do our utmost to fulfill customer needs and provide additional values from
excellent commercial and technical supports. With state-of-the-art technology and customer focus, LG Chem has
been awarded more than 3,000 Million Liter per Day (MLD) seawater projects since its establishment.

LG SW 4040 R - High Rejection membranes offer a combination of high rejection and low energy requirements to reduce
the total cost of desalination; suitable for medium to high salinity seawater applications.
