Household Domestic Drinking Water Purification Membrane Nanofiltration Element NF

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.Can do mix rolling according to your influent water quality and effluent water requirement.
