Seawater Reverse Osmosis (RO) Elements

TFS Series -Seawater Desalination RO Membranes
Product Description
Transfilm TFS series are high-end RO membranes featuring a supporting layer with high compression resistance, thick and dense flawless thin film layer. It has 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.
Product Highlights
· High rejection rate of salts
· High compression and fouling resistance and high cleaning efficiency
· Cost-saving of seawater desalination system

Seawater Reverse Osmosis (RO) Elements
TFS Series - Seawater Desalination RO Membranes
The TFS series are high-performance reverse osmosis membranes designed for seawater desalination. Each element features a robust support layer with high compression resistance and a uniform, dense thin-film active layer for reliable separation.
These membranes offer excellent resistance to wear and chemical degradation, and they are manufactured ready-to-use with no post-processing required. With broad pH tolerance, the TFS series allows more efficient cleaning with standard acid and base solutions, improving cleaning effectiveness and operational reliability.
Thorough cleaning and long-term durability allow the system to operate at lower pressures, enhancing membrane performance throughout its service life. The result is reduced operating costs and optimized long-term economics for seawater desalination systems.
