Home / Products / Reverse Osmosis Membrane Elements / Seawater Desalination (SW) / SWRO Membrane High Rejection Series SW-8040-440HR
UltraClean SW series are high-end RO membranes featuring a supporting layer with high compression resistance, thick and dense flawless thin film layer.
Product Description
With good wear and chemical degradation resistance, the membrane element does not need postprocessing during the manufacturing. It tolerates a wide range of pH, which enables more efficient and rougher cleaning using regular acid and base, therefore it has high cleaning efficiency. The membrane system can operate in long term under lower pressure due to thorough cleaning, therefore the membrane performs better during its service life. It can significantly reduce operation costs, and bring the best long-term economy to the seawater desalination system.
