Brackish Water
Reverse Osmosis (RO) Membranes

LG BW 400 R G2Highest rejection membrane equipped with fouling tolerant low dP spacer technology.
dOverview
LG Chem's NanoH2O™ brackish water RO membranes serve various municipal, industrial and commercial
applications. Incorporating LG Chem's proprietary Thin Film Nanocomposite (TFN) technology, all LG BWRO
membranes deliver reliable and superior performance with intrinsic anti-fouling properties.
LG BW 400 R G2 membrane elements deliver the highest salt rejection and productivity at lower feed pressures withrobust membrane chemistry for long-term stable performance. The RO element also incorporates a uniqueproprietary feed spacer technology for reducing differential pressure. The results are excellent anti-fouling properties
and lower cleaning frequency, chemical use, energy consumption, and total cost of plant ownership. Ideal applications
include wastewater reuse and feed water sources with high salinity brackish water.
