Trilite BWLE-4040 Low Pressure RO Membrane

Commercial 4 inch x 40 inch Low Pressure Reverse Osmosis Membrane

* Test conditions: 1500 mg/l NaCl, 10.3 bar (150 psi), 25 °C (77 °F), pH 6.5-7.5, recovery rate 15%.
* Pre-treatment must be used to protect the membrane (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler ...etc).
* Each membrane element may have ±20% variation of permeate flow rate.
* Minimum salt rejection 99.0%

Trilite BWLE-4040 commercial reverse osmosis membrane is suitable for water purification applications of water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water.

Trilite BWLE-4040 Low Energy RO membrane delivers high permeate flows and salt rejection at lower raw water pressures, compared to regular low-pressure membrane elements. The high salt rejection and low working pressure result in up to 30% lower energy consumption compared to standard elements.
