Replacement Brackish Water Reverse Osmosis Membranes

Brackish Water Reverse Osmosis (BWRO)

LG BW 4021 UES

Reverse Osmosis LG Chem Membranes Brackish Water

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 UES membranes offer high permeability at ultra-low feed pressure, significantly reducing operating costs: suitable for low salinity brackish water applications.
