Individual offer for 10+ pcs. Please use our ask form.

LG Chem’s NanoH2O™ seawater RO membranes - incorporated with innovative Thin Film Nanocomposite (TFN)
technology, reduce the cost of desalination while delivering superior water quality. Our seawater RO membranes
provide industry leading salt rejection and produce 20% more flow than membranes manufactured with conventional
technologies. We continue to leverage the technological advantages of our seawater RO membranes to expand our
market share, accruing more than 3,000 Million Liter per Day (MLD) projects for both new and replacement market
since the establishment.

LG SW 400 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.
