SW Series Seawater RO Membranes
Engineered with next-generation nanoparticle mixed matrix materials and fully automated winding technology, the SW Series delivers exceptional salt rejection and high-pressure resistance for desalination of seawater (TDS >10,000 mg/L) and concentration of high-salinity industrial wastewater, supporting sustainable freshwater recovery and resource recycling.
