Reverse Osmosis (RO) Membranes

Reverse Osmosis (RO) Membranes
 

Fouling resistant, high rejection, high flow, high durability
Fitted with low-pressure, fouling-resistant feed spacer technology

Overview
LG Chem NanoH₂O™ brackish water membranes serve many municipal and industrial applications and are used in major facilities around the world. Thanks to innovative Thin Film Nanocomposite (TFN) technology, all LG BWRO membranes deliver superior performance with fouling-resistant properties, suited to applications that require stable, reliable performance.

LG BW 400 R G2 membranes combine improved fouling resistance, high rejection, high flow and high durability, reducing the total cost of ownership. They suit highly saline brackish water and wastewater reuse with difficult feed water. They also incorporate advanced feed spacer technology, greatly reducing the pressure drop and the frequency of cleaning.
