Replacement Brackish Water Reverse Osmosis Membranes

Brackish Water Reverse Osmosis (BWRO)


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 400 R Dura membranes offer a combination of enhanced fouling resistance, high rejection, flow, durability, and reduce total cost of ownership: suitable for high salinity brackish water and wastewater reuse applications with challenging feed water. LG BW 400 R Dura membranes incorporate state of art feed spacer technology, which can greatly reduce differential pressure and cleaning frequency.
