Trilite BWHR-4040 RO Membrane
Commercial 4040 High Salt Rejection Reverse Osmosis Membrane
| Permeate Flow GPD (m3/d) | Stable Rejection Rate | Operating pressure |
| 2,800 (9.8) | 99.6 % | 225 psi (1,550 kpa) |
Test Conditions:
- Operating Pressure 225psi (1.55Mpa / 15.8kgf/cm2)
- Temperature 25℃ (77℉)
- Tested at 2,000mg/L NaCl Solution.
- pH 6.5~7.5.
- Recovery Rate at 15%.
- Each membrane element may have ±15% variation of permeate flow rate
* Pre-treatment must be used to protect the membrane (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler ...etc).
• 4”x40” 4040 Brackish Water RO Membrane.
• Provides high permeate flow and high salt rejection at hi salinity inlet water.
• High Performance in Rejecting Salts, TOC, SiO2
• Suitable for Treatment of Water with TDS up to 8,000ppm (NaCl solution)
• Trilite BWHR-4040 commercial reverse osmosis membrane is suitable for water purification applications of water sources with salt concentration lower than 8000 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.
