Denetlenen Tedarikçi 8 Inch Seawater Desalination RO Reverse Osmosis Membranes with High Rejection Fouling Resistance for Industrial Water Treatment Plant
UltraClean SW series special reverse osmosis membrane element for seawater desalination is a high-end reverse osmosis membrane element. The bottom membrane of the support layer has high compression resistance and thick skin.It is dense and has no defects on the membrane surface; it is resistant to abrasion and chemical degradation; and no post-treatment is required in the manufacturing process of membrane elements. Its wide pH resistance and high cleaning efficiency, can use ordinary acid and alkali for strong and efficient cleaning, because the cleaning is more thorough, the long-term operating pressure of the membrane system is lower, and the service life is higher. It can greatly reduce operating costs and bring long-term optimal economics to seawater desalination systems.
Product Highlights
1.High salt rejection
2.Compression resistance, contamination resistance and high cleaning efficiency
3.Improve the overall economics of the desalination system

Reverse osmosis(RO) system
Reverse osmosis process is the world's advanced, energy-saving and effective separation technology now, with a filtration accuracy of 0.001 μm, to completely separate and remove all particles of soluble salts, colloids, organics, microorganisms, viruses,bacteria, rust, and heavy metals in water. It requires pressure to force pure water across a membrane, leaving the impurities behind.
However, note that reverse osmosis systems are not ideal for treating water that is very hard and/or with significant quantities of contaminants. In this case, to extend the operating life of the membrane, the water should be pre-treated before entering reverse osmosis membranes (filtering, deferrization, etc.).
