SW Membrane

NL SW is a new generation seawater desalination reverse osmosis membrane with high salt rejection and high water permeability (low energy consumption). This type of membrane can be used for desalination of sea water with stable performance at low cost and is capable of producing drinking water directly from sea water with single pass RO.  SW can also be used for a number of other applications: concentrated brackish water desalination, power plant boiler feed water and other industrial water treatment, landfill leachate treatment and recycling of high value solutes through solvent removal.


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