Vontron Reverse Osmosis Membrane 4040-ULP11 ULP21 ULP31

Product details of Vontron Reverse Osmosis membrane ulp 11-4040 Stable Rejection Rate: 98.0% Minimum Rejection Rate: 97.5% Average Permeated Flow: 2,800 gpd (9.1 m3/d) Active Membrane Area: 85 ft Size: 4" x 40 Vontron ULP11-4040 RO membrane is a ultra-low pressure aromatic polyamide compound membrane element. It can work under ultra low pressure to reach as high permeate flow and salt rejection as regular low-pressure membrane element can, and is applicable to desalination of surface water and underground water. It operates under approximately 2 thirds of the operating pressure of regular low-pressure composite membrane, and achieves a salt rejection rate of up to 98.0%, which can decrease the investment costs for such relevant facilities as pump, piping, and container, etc. and the operating cost for the RO system, thus increasing the economic efficiency.Being suitable for the desalting treatment of those water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, etc., ULP11-4040 membrane elements are mainly applicable to numerous applications of various scales, such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production, etc.Operation ratings Max.Working Pressure: 600 psi Max.Feed water Flow: 16 gpm (3.6 m3/h) Max. Feed water Temperature: 45C Max. Feed water SDI: 5 Residual chlorine Concentration of Feed Water: <0.1ppm pH Range of Feed water during Continuous Operation: 3~1 pH Range of Feed water during Chemical Cleaning: 2~12 Max. Pressure Drop of Single Membrane Element: 10psi(0.07MCommercial Application Drinking water for restaurants Drinking water vending machines Aquarium water treatment Softened water for homes, hotels, commercial laundries and car washes Post-treatment of deionized water Pure water for pharmaceuticals, laboratories and electronics Hemodialysis Oil/water separation Product details of Reverse Osmosis Membrane ULP21 4040 - Model: ULP21-4040 - Reject: 99.0% - Average Permeate GPD(m3/d): 2400(9.1) - Active Membrane Area ft2(m2): 90(8.4) - ULP series of ultra-low pressure aromatic polyamide compound membrane element newly developed by Vontron Technology Co.
