Seawater Reverse Osmosis (RO) Elements

TFS8040-400XHR

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

Product Dimensions

Product Specifications

Flux and rejection rate is based on the following standard test conditions: 5.5 MPa (800 psi) pressure, 77°F (25°C), 32000 ppm NaCl solution and pH 8 for feedwater, and 8% recovery.
