KC-SW8040 Seawater RO Membrane Element for Large-Scale Desalination Projects
KC-SW8040 is a high-performance seawater reverse osmosis membrane element developed for desalination of high-salinity water under demanding operating conditions. Based on aromatic polyamide technology, it delivers reliable salt rejection and stable permeate flow in high-pressure RO systems.
Designed for feed water with salinity above 10,000 mg/L, KC-SW8040 supports efficient seawater desalination while maintaining long-term operational stability. It is widely used in municipal desalination, industrial water treatment, and other large-scale seawater applications.

FAQ
FAQ
Q1. When should a seawater SW RO membrane be selected instead of a brackish water BW membrane?
Seawater membranes are generally recommended for feed water with high salinity and applications requiring higher operating pressure and higher salt rejection than conventional brackish water systems.
Q2. What should be considered before selecting a seawater SW RO membrane?
Feed water salinity, required permeate quality, operating pressure, recovery rate, and overall system design should all be evaluated during membrane selection.
Q3. Which projects commonly use KC-SW8040?
KC-SW8040 is widely applied in municipal desalination plants, industrial seawater treatment facilities, offshore platforms, and coastal freshwater production projects.
Q4. Is KC-SW8040 suitable for OEM and EPC water treatment projects?
Yes. It is suitable for OEM equipment manufacturers, EPC contractors, and system integrators developing customized seawater desalination solutions.
