Brackish Water Reverse Osmosis (BWRO)
LG BW 4021 R
LG Chem’s NanoH20™ brackish water RO membranes serve various municipal and industrial applications and have been operating in 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.
