Product DescriptionProduct IntroductionUltra-Low Pressure Spiral Wound Polyamide Composite Membrane ElementAchieves high water production and quality equivalent to standard low-pressure membranes under extremely low operating pressure, significantly reducing customer operational costs.Utilizes specially treated membrane sheets with stable performance, lowering customer equipment maintenance and operational expenses.APPLICATIONSuitable for desalination and advanced treatment of brackish water, surface water, and tap water with a salinity of approximately 1500 ppm or less, such as small commercial water purifiers, hospital and laboratory water purification equipment, etc.Operating and Cleaning Limits:1. Flow rate and salt rejection are based on the following test conditions: 1500 ppm NaCl solution, 77oF (25oC), pH: 7.5, 15% recovery rate, and the rated applied test pressure mentioned above.2. The minimum salt rejection rate is 99.0%.3. The flow rate of a single element may vary within a range of ±15%.Maximum Operating Temperature: 113 °F (45 °C)Maximum Operating Pressure: 600 psi (4.14 MPa)pH Range, Continuous Operation: 3-10Maximum Feed Silt Density Index (SDI): < 5Maximum Feed Flow Rate: 16 gpm (3.6 m3/h)Chlorine Tolerance: < 0.1 ppmNotes:a. The maximum temperature for continuous operation at pH above 10 is 95 °F (35 °C).b. Under certain conditions, free chlorine and other oxidizing agents may cause premature membrane failure. Since damage from oxidation is not covered under warranty, it is recommended that customers remove residual chlorine through pretreatment prior to membrane contact.Technical SpecificationsMembrane typeMembrane ModelStable Salt Rejection%Minimum Salt Rejection%Average Water ProductionGDP(M3/d)Membrane area ft2(m2)Feed Spacer (mil)Test conditionTest Pressure psi(bar)Test Solution Concentration nacl(ppm)Recovery Rate%Ultra-Low Pressure Reverse OsmosisECO1-804099.098.510500(39.7)400(37.2)28100(6.9)50015ECO1-404099.098.52600(9.8)93(8.6)28ECO2-804099.098.511000(41.6)440(41.0)28ECO2-404099.098.52800(10.5)103(9.6)28Ultra-Low Pressure Reverse OsmosisLPO1-804099.399.011000(41.6)400(37.2)32150(10.3)150015LPO2-804099.399.011500(43.5)420(39.0)30LPO3-804099.399.012000(45.4) 440(41.0)28LPO1-404099.399.02500(9.5) 93(8.6)28LPO2-404099.399.02600(9.8)103(9.6)28LPO1-8040HR99.599.310000(37.8)400(37.2)32LPO2-8040HR99.599.310500(39.7)420(39.0)30LPO3-8040HR99.599.311000(41.6)440(41.0)28Low-Pressure (Brackish Water) Reverse Osmosis MembranePRO1-804099.599.310500(39.7)400(37.2)32225(15.5)200015PRO2-804099.599.311000(41.6)420(39.0)30PRO3-804099.599.311500(43.5)440(41.0)28PRO1-404099.599.32500(9.5)93(8.6)28PRO2-404099.599.32600(9.8)103(9.6)28Low-Pressure (Brackish Water) High-Rejection Reverse Osmosis MembranePRO1-8040HR99.799.59500(36.0)400(37.2)32PRO2-8040HR99.799.510000(37.8)420(39.0)30PRO3-8040HR99.799.510500(39.7)440(41.0)28PRO1-4040HR99.799.52000(7.6)93(8.6)28PRO2-4040HR99.799.52100(8.1)103(9.6)28Company ProfileSHANGHAI DUBHE ENVIRONMENTAL PROTECTION & TECHNOLOGY CO., LTD is a leading wastewater treatment solutions provider with 20+ years of expertise.
