4 Inch Commercial Seawater Reverse Osmosis Membrane for RO System with Good Cleaning Resistance

UltraClean commercial desalination reverse osmosis membrane elements can provide maximum water production while maintaining excellent salt rejection, high water production to meet the needs of offshore and onshore installations, while operating at lower pressures, which can reduce the size of high pressure pumps and cost and reduce operating costs. Due to the use of advanced automatic precision manufacturing technology, the performance of the membrane element is reliable and stable.Product  Highlights1.High flux and reliable stability2.Low operating pressureMembrane Specification  A inch(mm)B inch(mm)C inch(mm)21 (533)0.75(19) 3.9 (99)Performance Specification  Effective Membrane Areaft²(m²)Stablized RejectionRate(%)Minimum Rejectionrate(%)Fluxgpd(m³/d)33 (3.1)99.699.5540 (2.0)Test conditions: inlet pressure 5.5 MPa (800 psi); inlet temperature 25°C (77°F); inlet water quality 32000ppm NaCl; inlet pH 8; recovery 8%.Operating and Cleaning Limits  Maximum operating temperature                                                                                                                                                                                         113 ºF (45ºC)Maximum operating pressure                                                                                                                                    1000 psi (69 bar)Maximum pressure drop                                                                                                                                                                                                        15 psi (1.0 bar)pH rangeContinuous operation                                                                                                                                                                              2 - 11Short cleaning (30 minutes)                                                                                                                                                                                                                     1 - 13Maximum Influent Sludge Density Index SDI                                                                                                                                             5Free chlorine tolerance                                                                                                                                                                   < 0.1 ppmPermeate flow for individual elements may vary ±15 percent from the value specifed.Active membrane area guaranteed ±4%.Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.Company ProfileAbout UsProduction LineOur AdvantagesWhy Choose UltraCleanAfter Sales ServiceDelivery PackageFAQ 1.Are you a manufactuere or trading company?We are 100% manufacturer of RO and NF membranes which could help you get products with best quality and price from factory directly.3.Where is your company factory?Our Production Headquarter located in New Material Industrial Park, High-tech Zone, Ankang City, Shaanxi Province.
