LG Chem SW 400 R G2 Seawater Reverse Osmosis Membrane
Seawater Reverse Osmosis (SWRO) Membranes : Lowering the Cost of Desalination
LG Water Solutions’ NanoH2O™ seawater RO membranes deliver the industry’s highest salt rejection and 20% more flow than the membranes based on conventional technologies. Our seawater RO membranes significantly reduce the cost of desalination while delivering superior water quality. With state-of-the-art manufacturing and a customer-centric approach, LG Water Solutions has contracted more than 4,000 million litres per Day (MLD) in seawater projects in the past three years (2021).

Applications
What is reverse osmosis?
Reverse Osmosis is a process in which pressure greater than the natural osmotic pressure is applied on the high concentration side of the membrane, forcing the water to travel through the membrane from the higher TDS to lower TDS chamber, thus ‘reversing’ the natural tendency of water flow.
LG Water Solutions, a business unit of LG Chem, manufactures NanoH2O™ seawater everse osmosis (RO) membrane elements based on the breakthrough Thin-Film Nanocomposite (TFN) technology.
Thin Film Nanocomposite (TFN) technology improves membrane performance by embedding benign nanomaterials on the membrane surface. This innovative approach increases flux in seawater RO membranes by up to 20% without compromising salt rejection.
