BW Membrane

NL BW is a high water flux, high salt rejection brackish water reverse osmosis membrane, which can effectively remove various inorganic ions, colloidal substances and macromolecular solutes contained in natural water. It is capable of producing pure water supply for various industrial applications and boiler feed.  BW can also be used to treat industrial waste water with high salt concentration and municipal waste water, as well as produce water for pharmaceutical and food industries.


With NLCT's premium technology, BW membrane can be rolled into 8'', 4'' and 2.5'' spiral wound elements to accommodate different customers' needs. Specifications are available upon request.
