Beijing Origin Water Membrane Technology Co., Ltd.  

Product Name: Reverse Osmosis RO Membrane Module/Element Household Drinking Water Treatment/Purification Filter Model NO.: RO-1812-50 Activated Carbon Filter Type: N/a Filtration Grade: Nanofiltration Type: Water Purification Application: Household Material: Polymer Trademark: Beijing OriginWater Transport Package: Plastic Vacuumed, Corrugated Paper Boxes Specification: See specifications Origin: Beijing, China Product Description OriginWater (BOW) RO membrane is adapted the world-leading technology to produce steady membrane modules with high flux, high rejection for all kinds of RO household water purifiers. BOW RO membrane effectively separates soluble salt and the matters which molecular weight bigger than 100, the regular rejection can be over 95%, to ensure the household drinking water to be absolute safe and healthy. RO technology is widely used in drinking water purification, boiler makeup water, seawater and brackish water desalination, industrial DI water and electronic ultrapure water preparation. It reduces operational cost and concentrated water discharge by applying RO process before ion exchange and electroosmosis process.Advanced self-development and manufacturing make the reaction fast based on water purifier manufacturers, dealers and end-users' feedbacks, and capable of supply customized membrane products. For easy storage and application, BOW RO membranes are all dry membranes.Performance and testing conditionsModelPerformanceTesting conditionsFlux(GPD)Rejection(%)Testing pressure (psi)TempºCTesting solution Solution concentration (ppm)pHRecovery(%)RO-1812-5050≥936025CaCl22507.5-8.05050≥966025MgSO42507.5-8.0151.Produced water and rejection rate are based on the following conditions: the pH of DI water solution, 25ºC, the performance can be tested after testing pressure recycling runs for 30 minutes with a fixed recovery rate.2.The produced water capacity of individual module can be vary within 15% the number shows above.SizeModelSizeArea (m2)Diameter (mm)Length (mm)RO-1812-500.4144298A=298mm B=256mm C=21mm D=17mm E=44mmExtreme operational conditionsMaterialMax feed tempMax operational pressureMax feed SDI15Max feed hardness (by CaCO3)Free chlorine concentration of feedContinuous feed pHPA composite membrane45ºC300 psi5400 ppm< 0.1 ppm3~10*The initial 30 mins producing water should be discharged.
