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.

1.
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.
