Seawater Desalination Reverse Osmosis SW Series Membrane Elements
Detailed description
(1) Product Positioning
SW-series membrane elements are suitable for desalination of high-salinity water (TDS < 45,000 mg/L) and are widely used in seawater desalination, the treatment of highly saline brackish water, as well as the concentration and reuse of high-salinity wastewater, among many other applications.
(2) Product Features
By precisely controlling the membrane separation layer, it is possible to achieve an optimal balance between desalination efficiency and water production; meanwhile, optimizing the membrane element’s structural design enhances its pressure‑bearing capacity.
(3) Product Performance
