4”x40” 4040 Low Pressure Membrane
2400 gpd / 99% / 150 PSI
Typical operating pressure of 150PSI (1050kPa)
Vontron ULP21-4040, 4 inch x 40 inch Low Pressure Reverse Osmosis Membrane
Vontron ULP21-4040 ultra low pressure 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.
Vontron ULP 4040 series of low pressure membrane element are based on a 10.3 bar (150 PSI) test pressure.
Salt Rejection: 99%*
Permeate Flow: 2400 gpd (9.1 m³/day)*
Membrane Area: 90 ft².
Diameter / Length: 4 inch / 40 inch.
*Test conditions: 1500 mg/l NaCl, 10.3 bar (150 psi), 25 °C (77 °F), pH 7.5, recovery rate 8%.
*Pre-treatment must be used to protect the membrane.
Vontron ULP 4040 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.
