Vontron ULP21-4021, 4 inch x 21 inch Low Pressure Reverse Osmosis Membrane

Vontron ULP21-4021 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 4021 series of low pressure membrane element are based on a 10.3 bar (150 PSI) test pressure.

Product Specifications:
Salt Rejection: 99%*
Permeate Flow: 950 gpd (3.6 m³/day)*
Membrane Area: 36 ft².
Diameter / Length: 4 inch / 21 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 (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler ...etc).

Vontron ULP 4021 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.
