Beijing OriginWater (BOW) nanofiltration (DF) membrane is adapted the world-leading technology to produce steady membrane modules for all kinds of household water purifiers. BOW DF membrane effectively removes the organisms, microbes, virus and most of the ions in water to ensure the household drinking water to be absolute safe and healthy. Advanced self-development and manufacturing make the reaction fast based on water purifier manufacturers, dealers and end-users' feedbacks, and capable to supply customized membrane products. For easy storage and application, BOW nanofiltration (DF) 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.
