Brackish Water

Reverse Osmosis (RO) Membranes

LG BW 400 R

High Rejection

LG Chem’s NanoH2O™ brackish water RO membranes serve various municipal and industrial applications and have

been operating in the major utilities around the world. Incorporating innovative Thin Film Nanocomposite (TFN)

technology, all LG BWRO membranes provide superior performance along with intrinsic anti-fouling property and are

suitable for applications where consistent and reliable performance is a must.

LG BW R membranes offer a combination of high rejection and reliability: suitable for high salinity brackish water and

wastewater reuse applications.
