Description

LG BW 400 ES L

Energy saving brackish water RO membrane with an advanced 34 mil low dP feed spacer technology

Equipped with fouling tolerant low dP spacer technology

LG BW ES L is highly permeable at low feed pressure and incorporates a unique proprietary feed spacer technology for reducing differential pressure. The results are excellent anti-fouling properties and lower cleaning frequency, chemical use, energy consumption, and total cost of plant ownership. Ideal applications include feed water sources with low to medium salinity brackish water.

LG Water Solutions’ NanoH2O™ brackish water RO membranes are gaining traction with major utilities and industrial end-users worldwide. The TFN technology, coupled with intrinsic anti-fouling properties, delivers reliable performance and reduced operational downtime, leading to a lower total cost of plant ownership.
