Replacement Brackish Water Reverse Osmosis Membranes

Brackish Water Reverse Osmosis (BWRO)

LG BW 440 ES

Reverse Osmosis LG Chem Membranes

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 ES membranes offer high permeability at low feed pressure, significantly reducing operating costs: suitable for low to medium salinity brackish water applications.
