Low Pressure LG RO Membrane BW 400 ES

NanoH2O BW 400 ES, Low Pressure Reverse Osmosis Membrane 

* Test Conditions : 2,000 ppm NaCl at 25°C (77°F), 150 psi (10.3 bar), pH 7, Recovery 15%. 
* Each membrane element may have ±20% variation of permeate flow.
* Minimum salt rejection 99.5%
* Pre-treatment must be used to protect the membrane (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler ...etc).

• 8”x40” Low Pressure Brackish Water Membrane.
• High permeate flow rate and salt rejection at low feed pressures
• Suitable for low to medium salinity brackish water.

LG BW 400 ES Energy Saving Brackish Water RO membranes offer high permeability at low feed pressure significantly reducing operating costs; suitable for low to medium salinity brackish water applications.

It operates at Low Pressure (10.3 bar / 150 PSI) inlet feed water pressure.

LG BW 400 ES Enery Saving BWRO membranes offer a combination of high rejection, high flow, low pressure feed water, reliability and durability, 

LG Chem’s NanoH2O™ brackish water RO membranes serve various municipal and industrial applications and major utilities around the world. LG BWRO membranes, all incorporated with innovative Thin Film Nanocomposite (TFN) technology, are offered in industry standard configurations and can easily fit into existing and new RO plants.   

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.
